How many uses/hours is the mask useful for?
Cotton only masks are most useful for wearing over the N95 masks to keep them clean and prolong their use. They can be changed and laundered more often.
It really depends on use and exposure. I am looking into using UV light and heat to sanatize them without damaging them.
Agreed! Thank you... Just to be clear I am NOT saying Don't Make cotton masks. I am saying that I believe this mask to be far more protective for respiratory illness. If you can't make these masks than please make the cotton ones. We can still use them Too!
@@dr.ryansouthworth7796 What about microwaving them?
Hello,
for everyone who has no printer, I measure the sewing pattern:
The bottom line is 24cm (approx 9,5 inch), the top line is 7 cm (approx. 3 inch)
From the middle of the bottom line, to the middle of the top line - it's 10cm high (approx. 4 inch)
Right and left from the bottom line it's 2 cm high before it begins to round.
Length of the elastic 26-30cm (10-12 inch)
I hope it's understandable, because my English is not so good.
Greetings from Berlin Germany :)
MissisPoirot thank you for this!!
@@user-sq5dd9od5x Hello :) Off course these DIY masks just protect you a very little bit, it protect more the others than yourself.
But why are there warnings for this material?
When printed, my pattern came out:
length 23 cm/9 1/4'
width 9.5 cm/3 3/4'
I got only 2 masks per bag "Hoover S"
Total width of bag 31 cm/12 1/4", length 35 1/2cm/14"
Variations in printers? Please share measurements of Hoover Y.
Keep in mind that laymen are not accustomed to wearing masks. If out and about and adjusting the bridge of the mask, for example, they may put contaminated fingers near their eyes and nose, thus potentially infecting themselves.
@@user-sq5dd9od5x What kind of warnings?
Thanks
Hi Doctor, you the front line medical professionals are the Heroes. I have four of my family members working in Hospitals. God bless you and your family. God Help and Bless all of us.
Many thanks Dr. and Mrs Southworth, Stay well! ♥️
Thank you for the info. I especially apreciated seeing your CTR ring:) Thanks for a Choose The Right reminder.
IMPORTANT: from Simone Tattersall (below): "NOTE!!!! Hoover has responded that their HEPA bags are unsafe for making masks. Some bags are made of fiberglass particles so not safe to cut & breathe through."
Good to know. Unfortunately, desperate times are leading to this option, but thanks for letting us know. Your comment should be pinned at the top for all of us to see.
There all lying ! They want us dead ! There part of the CCP !
Catherine S. Todd @glorytoGod I inquired with 3M on 4.2.20 and they gave the warning that Hepa-filters are made for an entirely different purpose and they do not condone filters for use in home-made masks.
Why isnt the doctor taking down this video? This is not cool!
I wonder it air conditioning filters are made with fiberglass though.
These women who run an industrial sewing shop tested a ton of materials before settling on 2 brands of shop towels that worked best and designing a better face mask. The shop towels filter essentially as well as the HEPA vacuum bags and without the fiberglass/chemicals issue:

That awkward moment when you realise you have a bagless vaccum cleaner.
LMAO!
😂😂🤦♀️🤦♀️
hahahahah, I do to, so I bought bags on Amazon! lol
oh and FYI, the Kirby bags don't have an interior plastic layer!
Same here 😂😂
That is absolutely brilliant! Thank you. Never thought of the hepa vacuumed bag.
Those bags have fibre glass which is not good for the lungs. Hover sent out a notice. We need to be careful.
Well done from one ER doc to another. Thanks.
NOTE!!!! Hoover has responded that their HEPA bags are unsafe for making masks.

Link? It's not on their website
I can’t find this anywhere but scary if it’s true.
Serge the edges after cutting them. Also do not put it next to your skin, it shold have a layer between it and you. Also the "pillowly" side which if smooth should be towards you. I am a DPT, and trust me, I sew, and had to make a smart and healthy effective choice.
@@briangallagher449 I looked for the Hoover Y bag she used, and it had "WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov" in the specifications section.
Here's a doc making the same point: th-cam.com/video/qiYbXsIcI7E/w-d-xo.html
Shouldn’t the company that makes these bags make masks instead? They could save so many people. Great video
I'm sure they could , but it would take awhile since I am sure that would require a bit of retooling.
You be surprised how many companies are helping out. Also there’s restrictions when owning a company not to mention approval can take forever. What would be great if family and friends can make these and the company donates Materials. Great ideal for my family when going out for things we need. Going to try this!
@@ReneeHits
They've had a 3 day turn around from car companies and sewing factories. But you're right, they don't have seamstresses or sewing equipment. My guess would be these guys should send fabric to the sewing companies making masks.
achanwahn brilliant idea! I hope someone else has thought of this and if not this idea needs to reach the powers that be! Get that hepa material from the vacuum bag companies to the people making the masks because it will cost a fortune to repurpose vacuum bags and only get 4 masks out of a bag. And especially now that wages, hours, and jobs are being cut. Get that material to the sewing manufacturers ASAP please!
Wonderful idea. Contact a news channel.
They all say fibreglass is a bad idea so I used my old asbestos soldering mat from my plumbing days. The nurses on the cancer ward helped me type this, God bless them.
Asbestos is a carcinogen!
there is fibreglass in "asbestos",
Thank you very much for sharing and I so needed this too.. GodBless
Thank you for the instructions! I made a set of these for my family. I didn’t have pipe cleaners so I sewed a fabric channel to slip a piece of braided floral wire to work as a nose pinch.
I used floral wire too.
@@theresefleddermann398 Yeah, but you are sewing the sides for the top and bottom, I worry about that, on the sides, no nasties get thru there?
@@theresefleddermann398 but she sowed in the video?! 😫 im so confused
katherine RoseMore she sewed in an area of the seam allowance. Different than sewing inside the area where filter is working I think.
Don't--- there are glass particles in the HEPA filter when cut as well as chemicals in the filter.
Praying for our doctors and nurses that are on the frontline taking care of us. You are the real heroes And sheros. I love and appreciate you. Thank you Sir, and God bless you all. Praying for humanity🙏🏾
Amen to that!
Why isn't god or Allah stopping the virus? Because he does not exist.
Thanks a very nice project that helps a lot of people. I did something similar and i have found that instead sewing you can use the heat sealer of a vacuum packaging machine (many of us have one to preserve foods) to ho seal the edges. it works fine and give a very robust seal. In this way you avoid to make holes in the fabric.
I hope my suggestion would be useful.
Thank you for posting this I shared it on my Facebook profile. Stay safe and thank you for all that you do
I am a nurse working in the UK. Thank you for giving me the knowledge of how to make the safest face mask. Viruses cannot get through this face mask because of their size. With this face mask I am confident that I can work safely today. Thank you Dr Ryan Southworth.
Why would vaccum filters be designed to not allow particles trough that are only a few nanometers big?
I wasnt sure if the NHS would allow these masks, if they were made and delivered. Thank you.
@@yanusanders7686: The HEPA designation means that it's designed to filter a high percentage of very small particles -- in this case, 99.97% of particles down to 0.3 microns. HEPA certified materials are popular for air filters and vacuum bags for people who have allergies and asthma, cleaning around immune-compromised individuals at home, etc.
PIPPAD2018 EMMANUEL did someone pay you to post this very paid sounding endorsement?
@@dasirrine do you mean 0.3 micro metres? Because that would be too big. Corona viruses are only a few nano metres big
Personally I think it would be easier and possibly more effective to make cotton masks with pockets that you could then insert your homemade vacuum hepa filters inside. Then you would be able to dispose of the filter and wash the cotton mask to reuse
No, the HEPA material itself needs to fit very snugly to your face, it can't be merely in a pocket.
That what I've been doing the pockets work great.
Kelsey A that’s a popular design too
While it is better than nothing, it’s not a comprehensive filter. The particulate will just take the path of least resistance. This is why they always say a HEPA filter needs to have an airtight seal to be truly filtering out particulate with 99.7% efficacy. Applying the same concept, the sides of the mask would also have to be airtight in the worst-case scenario of a sneeze where the force would lift the mask off your face.
I THINK IT MUST EASIER TO TURN THEM INTO THEIR LOCAL AUTHORITIES UNLESS PERHAP THEY ARE IN ON IT
Thank you for this great resource Doc. I ordered HEPA bags from Home Depot. Unfortunately I chose ones that only yielded me 3 per bag.
I used doubled up twist ties for the bridge.
TIP - Since I only had a limited amount of elastic strap I McGivered a set of strong alligator clips on the ends of the elastics and quilt-stitched the ends of the mask so the clips could make good purchase and not tear it. It works great, and I can simply move the strap from mask to mask.
I'm rotating a set for every day of the week... 7 days to allow the virus to die.
Be well and safe everyone.
Cut up pantyhose straps are a good elastic, make sure the stripes are wide (at least 1 inch or 2,5 cm or more, you can test), they get much longer and narrower once you stretch them. They do not fray, especially not once they were stretched, and they are also not disintegrating.
or hair elastics (you can use an inelastic strap to cover the distance, and the elastic just adds the option for adjustment in the last inches.
HEPA material is not safe, producers like Hoover have warned (see the comment section). BUT:
search on smartairfilters(dot)com with What are the best materials for making diy masks. (the humble tea towel ! or cut up cotton shirts).
smartairfilters.com/en/blog/best-materials-make-diy-face-mask-virus/
I am sure professional, bought masks are better, but you can come pretty close, despite the "holes" in the woven fabric.
In practice a close FIT is very important.
I am astonished that tea towels (the fabrik is loosely woven) should be that good, but they did the test. The material is also meant to be absorbant, and that does not suit the virus or bacteria with which they tested.
Also the article about:
N95 masks versus surgical masks
(the finding during the flu season. Officially N95 is less protective. But it is much more comfortable to wear, and brings almost the same results, that was a clinical study).
They also have an article: What’s a Reliable Way to Disinfect Masks from Viruses Without Harming Effectiveness?
- the materials of bought are impregnated (water repellant, that is intended to help also against viri and bacteria getting through) and you lose that by washing. The hull of the virus is weak it breaks if exoses to soap or detergent, thus the 20 second hand washing. It is not only that you rinse it off, the soap literally destroys the virus.
DIY cotton masks can and should be washed. probably hanging them up to dry - even better in sunlight - and washing every other days should work.
The virus does not fare well on absorbant surfaces (like cardboard) when they are dry.
This is totally irrelevant and not at all something I usually do, but... MacGyvered.
@@xyzsame4081 I use multiple layers of cotton fabric, sheets with the highest thread count you can find are excellent for material, and I put a layer of 100% unbleached cotton quilt batting between the layers. My masks are very comfortable, even though they are thick they are all cotton and breathable. I'm very chemical-sensitive, and this is what I ultimately came up with that works for me. The pattern I use fits very well, and doesn't cause my glasses to fog.
She makes a very good point here, don't use pins when sewing the pieces together since that makes holes.
You shouldn't be wearing elastic straps, or have a mask that does not cover your entire head, and block off air supply. I know this is well known now, 5 months after your comment, but we in Sweden knew from the start that a) the virus was a mild flu virus and b) no mask a human could breathe through would protect against a flu virus. Our death toll has not risen, compared to last year and the year before and the year before and... so we're doing something right. Take off the masks; they're causing bad infections.
Thank you for your medical and home family support. I will pass this on to my customers, family, and friends. Stay safe. GBYGA #2020
If you’re concerned about using Hepa bags to breathe thru, cut an extra pattern piece out of cotton and attach it as a liner. Really easy to modify the instructions to add the extra layer (on the INSIDE!)
Cotton wouldn't filter out chemicals. It's all about the size of the holes the air passes through...anything smaller than the holes in cotton fabric would pass through easily. That's why you can breath through it at all.
@@athenawilson4019 Lincoln Street Ballet School is talking about ADDING a cotton liner to the inside of the HEPA mask.
John J I think he knows that, it still doesn’t make a difference. Adding cotton to the inside of the mask would not filter out the chemicals or whatever from the hepa bag
@@lasrider11 it's not chemicals, it's fiberglass particulate they're concerned about
@@athenawilson4019 If you use a tightly woven cotton like from bed sheets or a heavyweight t shirt it should block the fiberglass particulates. Some people use denim but I don't know how easy it would be to breath through jean material.
I just made over 5 dozen of these masks a few days ago and delivered them to my local hospital who were very grateful to have them. I’m in the process of making more . Thank you Dr. Southworth for the video making us safe. The only other thing I have to say is I wished I knew about this before I contracted COVID.
Momo Drawings your welcome and will be delivering 6 dozen more this weekend. I also have orders for another two hospitals and will have help making them.
@@Kat-fw9se I'm sorry to hear about that. You are truly a saint, we need more people like you.
OK am I the only one that feel like you are putting working in danger by making mask knowing that you have the virus??? Are yall really not reading what this person just said???? Im confused 😳... but you need to quarantine yourself from making mask asap!!!! Im not sure if you are trying to be funny or if you are really a saint, but please do not put our workers at risk, please!
@@TriggaTreDay get outta here
Lady LaTre'viette Phantumhive I don’t have the virus now nor did when I made the masks. I do wear gloves and a mask when making them. I said I wished I knew about these mask WHEN I had COVID.
Very easy pattern and easy to follow instructions! I had a yellow t-shirt, shoelaces (for straps) and some stiff fabric and actually used this pattern to make some "playtime" masks for some kids in isolation. It made them soooooo happy. Will eventually make some "real" masks once I can buy supplies. Thank you!
Thank you very much for this great information and teaching us how to do it!
THANK YOU FOR SHARING AND BEING OUT THERE ON THE FRONTLINE BATTLING THIS EPIDEMIC. MAY GOD PROTECT ALL OF U N THE MEDICAL UNIT HELPING PEOPLE. GOD BLESS!!🙏🙏🙏
Why isn't god or Allah stopping the virus? Because he does not exist.
It is a neat idea that I had been looking into myself recently. However, most HEPA filters are made of borosilicate (fiber) glass or polypropylene fibers with a percentage of acrylic binding (think latex paint). That simply ISN'T SAFE for individuals with a latex allergy-or really anyone else for that matter-as you run the risk of inhaling copious amounts of fiber glass material. There are "allegedly" synthetic brands that MAY not contain fiber glass (though still contain the other materials mentioned), but the specifications and transparency of that is murky across different brands. I'm currently looking into other non-woven materials for a safer option.
...Just so you know, one of the tell-tale signs of too much fiber glass inhalation is a sore throat-for those that still choose to make these. Stay safe everyone.

IT CONTAINS FIBERGLASS... DON'T USE. HEPA FILTERS only down to point 5 microns, while the c19 virus particle is .3 microns. Won't work... You are putting people at risk for breathing in fiberglass, or other unknown material... DON'T MAKE THESE MASKS> I just read the guidelines for this where he shows the link, NO WHERE DOES IT SAY TO USE THESE BAGS. It talks about a filtering system in the room, and other equipment, but not the masks. You are fooling yourself if you feel this will keep you safe... You will be inhaling fiberglass or other unknown material that will severely damage your lungs, or whoever wears these masks.

I called the manufacturer who told me they were made of PTFE. But even if it was fiberglass, I will still use this over the risk of illness. Also, the CDC guidelines talk about DIY/homemade masks. I never said or insinuate that the CDC endorsed this, in fact I made a very clear statement that this was a very unscientific study. Just for clarity: HEPA filters take out 99.97 down to 0.3 microns and the viral particle is about 0.12 microns. However, the virus doesn't just float around in the air without being surrounded by moisture. SARS-CoV-2 (the virus) that causes COVID-19 (the disease) is in droplets. When a droplet containing the virus hits the filter it is absorbed by the filtration system and gets stuck to the fabric. It is interesting to note that the N95 masks that are recommended by the CDC only filter out 95% of particulates. It is also interesting to note that the PAPR devices (think hood-like space suits) are considered better than N95 and have... guess what....... A HEPA FILTER!

To alleviate any concerns... here is a link to a HEPA filter mask made by 3M... it is (of course SOLD OUT) but it confirms the current use of HEPA filtration/safety...
www.achooallergy.com/3m-8293-mask.html
Please note the description:
When it comes to personal filtration of particles, the gold standard is HEPA. You get that and more with the 3M 8293 HEPA filter face mask. Not only does this respirator offer full HEPA filtration, removing 99.97% of all particles 0.3 microns or larger, but unlike other masks, it's rated to remove oil based aerosols and particles. Soft and lightweight, this fully adjustable mask exceeds the CDC recommended N95 rating to help prevent the spread of viruses like the flu, SARS, H1N1, and Avian flu. A valve allows for better air flow while letting moisture and warmth escape. Perfect for the workplace, at home, or on the go, the 3M 8293 HEPA mask is an inexpensive solution for filtering out allergens, oily aerosols, viruses, and germs. Replace after 150 hours of use. One size fits most.
@@SCORP1ONF1RE Thank you for the quick reply. I mean this with no disrespect to the doctor, but I stopped reading when he stated, "...But even if it was fiberglass, I will still use this over the risk of illness." While this doctor may be fine with ingesting fiber glass, many other doctors and medical staff would certainly not be okay with doing so. And we still can't ignore the fact that other chemicals such as acrylic and latex are found in these products as well and could cause severe negative reactions for those being supplied with the masks-even if there was no fiber glass present. It is also important to note that Hepa filters come from different manufacturers-who have different procedures and use different materials. Medical grade Hepa filters versus random vacuum Hepa filter bags...I'm not sure one equates the other; clarification is needed. Most people taking the doctor's advice and sewing these masks will be sourcing their material from all over the place, which may impact quality as well.
Even though this video was prefaced with a lack of scientific fact, it is still endorsed by a doctor. If we're being honest, the average layperson will take a doctor's advice like its scripture-which is dangerous. The cons-in addition to the pros-should of been clearly addressed IN THE VIDEO, as the majority of people watching will unfortunately not have the foresight to do their own research-because the information is coming from a doctor. That is irresponsible. I understand the idea behind wanting to find better protection for those in the hot zone right now (and it is a desperate situation)-but we can't neglect safety in other areas. I can not be encouraged to willingly sew masks for medical staff knowing that there is even the slightest chance that a single person receiving a mask could be adversely affected. That is not my call to make-nor this doctor's. They are going through enough as it is.
I will continue to do some more research on my own about this. In the mean time, I will support hospitals with what they are suggesting I support them with. And I feel that those making these masks should send them with a disclaimer. That being said, most hospitals, at least where I live, will not accept these anyway, so I'll stick to what they are asking for, for now.
Though I have plenty of the stuff needed, I'm not making any damned masks - too controversial.
Don't want to accidentally kill someone.
susan hawkes :/ yeah it sucks that we don’t have any guidance from the cdc or who on what we can safely do at home. I’m allergic to many things and don’t want to breather fiber glass don’t know how to sew either so I’m kinda screwed to try to make a cloth mask
@@SCORP1ONF1RE Also, the water droplet containing the virus holds a slight charge, which is attracted to the electrostatic layer.
This design looks great! I have a friend that is making mask and she suggested that vaccum cleaning bags have fiberglass in them and that wouldn't be a good thing to breath.
I've done a lot of research into this and have yet to find a vacuum bag that contains fibreglass. They are composed of spun polypropylene and sometimes paper or plastic th-cam.com/video/vmYt_wtaLCk/w-d-xo.html
Imagine fiberglass reinforcement in vacuum bags. How ridiculous! You Tubers at your worst.
@@teachtairai honestly, people can't just do this? www.vacuumcleanermarket.com/news/do-vacuum-bags-contain-fiberglass/
Super cool! I made cotton masks and used my HEPA vacuum bags on the inside to filter. I only had one of the bags and thought it was better than only getting four masks for my family of five. Stay safe and thank you!
Rhonda, what pattern did you use? I'm thinking that may be the way to go.
This is so helpful! Thank you so much. *I did giggle when you talked about some of us cringing when you used your fabric scissors on the paper* LOL 🙋🏼♀️
I also giggled. Because if i see anyone in my home reaching for my fabric scissors I yell "please dont touch my special scissors ". Lol
I just made a few of these. I find it much easier to do the sewing after marking, but before cutting out the pattern. That means you have plenty to hold on to while sewing. Instead of pipe cleaners, I cut up a soft drink can, cut half inch wide x 6 inches long strips (5 inch for small) and folded them in half. I used Miele GN vac bags, and could sew three only from each one, two using the manufacturer seams and one sewn all around.
bob` cumming,
Brilliant idea with the cans.
I used the wide coffee bag ties that go along the top of package. They are about 3/4cm wide and work perfectly.
Can you explain what you mean you used a can
Great idea about the soda can!
Brilliant idea about aluminum can cut up!
Where did you find the pattern? Also, how long can we wear this since it is paper?
Thank you Dr. Southworth and your coworkers for your service. Thank you Mrs. Southworth for your safe face mask video. God Bless all of our frontliners and essential workers.
It makes a lot of sense. Thank you and my deepest appreciation for your wife. Thank you both
his wife is stupid and they both will make loads of people die of cancer instead, the bags contain glass and it's not fit for breathing from it.
It is getting crazy …. Actually I have been talking the microwave and toaster while drinking coffee and we all agreed that things are getting bad. The vacuum was unsympathetic..... Told me to just suck it up, but the fan was more optimistic and hoped it would all soon blow over! I didn't mention anything to the washing machine as she puts a different spin on everything. Certainly not to the fridge as he is acting cold and distant. In the end the iron straightened me out as she said everything will be fine, no situation is too pressing. The toilet looked a bit flushed. When I asked it's opinion it didn't say anything but the door knob told me to get a grip. The front door said I was unhinged and do the curtains told me to...... yes, you guessed it.....pull myself together.

No God, Just the law of karma, you do good thing you have good results, you do bad things you get the bad results
I checked with the company that manufactures vacuum cleaner bags I use around my flat (EnviroCare Technologies) and their FaceBook page states that their bags do NOT have fiberglass (and NEVER did). They recommend using vacuum bags as filters, if we (McGivers) really need to DIY-construct anti-coronavirus masks, etc. Good luck Lads and Ladies!!!!
Did they tell you ALL of our mass produced vac bags, including HEPA, come from China? What we get is products set to their standards, not ours. Something to think about.
That’s a good idea ... I have a lady that makes my cotton mask for me.. She sent me a pic of it in the middle of the making of it. It was a Synthetic hepa filter built in it.. Glad she showed me and she can make pretty much anything u want. I do how ever like the clever idea of how these masks were made!!!! Good Job,,,
You're the best Dr. Southworth! Keep up the videos on this channel.
Paul Reynolds Thank you, please share this with as many people as you can!
Our shop is making filtered masks aswell, we did testing with a nurse and EMT on our filter, it's called pellon, all upholstery shops have it for sofa skirt lining.. if you pour water on it, NONE drips through , but it's still breathable . In our area ,some doctors and nurses are allowed to wear them..we now need over 5000, all donated..
Pellon is a brand that makes many types of sewing interfacing. Some woven, some not. Some fusible (will melt when mask is sterilized) some not. Please be specific with what you used. I have some Pellon interfacing with holes about 3mm. Useless for filtration. Please be specific for science.
Probably the heavy one? Could you please answer Jennifer’s question, please.
I watched a video (don't remember which one) that said Pellon 911 interfacing works best but also a couple of different ones work as well.
I have some Pellon interfacing and it immediately absorbed the water when I held it under the faucet. So not sure which kind is the right kind but mine isn’t. Also want to add that splitting the elastic down the middle to make it a quarter inch instead of the half inch size I had, just kept unraveling so I had to replace all the masks elastics that I had already done with something else. I did find some extra large hair elastics and if you cut it to open it up it works real well and I just used a silicone small hair elastic to secure them which can be rolled up or down to make the loop tighter or looser. I hope that helps to spare someone the frustration I just experienced!
I would like more information...
Awesome, thanks to both you and your wife
Finally received the hepa vacuum bags and made the masks in no time at all. For a larger face I added 1/2” all around and added 1” to the elastic. Very easy instructions to follow.
Bets mask , is activated charcoal layered between to layers of cloth,,,very easy to make , and charcoal is used in fish tank filters
@@joerej1042 activated charcoal is probably on step better than no charcoal but it is not the best. An Electrostatic filtering method where an electrical charge is applied to any incoming particles at the outer side of the mask and then the opposite charge is used to collect the particles on the inner side. This way no particles of any size can get through the mask. The downside is that the small watch battery needed would have to be check regularly to make sure it was working and keeping the system electrically charged and how to then remove the captured particles from the mask or dispose and use a new one.
I work for a company that makes mask for hospitals . Prestige ameritech in North Richland hills tx. We are trying to get as much mask made and get shipped out same day cuz we know so many hospitals are in need of mask
Maria Moreno Do you make just the surgical masks, or does your company also make the N95’s?
Maria Moreno can you guys make 3000 N95 we don’t have any in the hospital in North Dakota. The first responders are getting sick and they already half of the work force
Thank you for all you and your company is doing.
Thank you! Please keep doing it. I know it's not easy. :)
@@MagnetechSolidSolutions I was wondering about that...
Dr. Southworth, my name is Dr. Enrique Varela, I am an internist taking care of patient in long term care facilities. As you know these patients are in the high risk population group. The amount of PPE in nursing homes is limited as in everywhere else. After watching your video, my wife and I were able to prepare 30 masks in one night. I am thinking to teach the staff in my facilities how to make this masks with your permission, we want to protect our patients and our staff as much as we can and this will be an excellent way to provide more safety. Thanks to you and your wife for the great video and the great idea.
*Do NOT sew* glue the edges. Sewing leaves huge holes. Completely defeats the purpose of the HEPA filter.
@C. Lord So industrial respirators and some of the N95 masks do, they use hepa filters.
I need to make 5 masks for school. Thank you.
Bravo sir. Thank you for using materials which will actually provide some level of filtration!

Ron Strobel I’m sure she can buy any machine she wants!
@C W I agree to a certain extent. However, if a woman is spending HER OWN MONEY, she doesn't need permission. If one is married and money is household property, one does.
Dahlene and Amy stop throwing shade at that sweet man who just wanted to show appreciation for the doctor's wife's efforts.

A couple of things regarding the elastic:
1. Elastic needs to be stretched at least a few times before you cut it to length, or it will stretch out longer than it's supposed to be when it's worn.
2. Unless you're using the hard to find Fantastic Elastic, elastic should NOT be cut lengthwise as it will unravel.
Given that these don't have to last long (single patient use in the best-case scenario), and given that most people won't have Fantastic Elastic at home, cutting the elastic is probably OK. I wouldn't, but if it all you have... Or you could just use 1/4 inch elastic if you have it.
Lots of work for single use. These are not single use.
Single Patient use maybe; like perhaps just one person of course. But unless you can wash it or disinfect it somehow; it’s not practical. The best thing to do is make a cover that can be washed and have an insert
I think the solution to elastic would be to simply make ties instead. That way you don't have to worry about if these elastic is too tight for someone to wear it for hours or too loose for people with small heads or it stretching. Ties can always be adjusted for the right fit
I used hair bands on the ends . Then to tighten to snug fit I also used string or ribbon . Instead of the hair bands going around the ears I tied the string onto the hairbands so you could pull tight and get it snug. It was a good seal even under the chin.
Also if you cant find pipe cleaners you can use aluminum foil baking pans. cut 1in. x length of face 4in maybe?? and fold in the raw edges so no poking happens.
Looks wonderful ! Thanks for sharing ! Greatly appreciated!
Thanks for the idea of using vacuum bags for filters. Now I can design a more practical washable mask with inserts using the filters.
Other options to pipe cleaners are1) aluminum soda or beer cans. Cut aluminum into strips and fold them two or three times 2) Acco metal paper clasps.
Also gardener's wire and twist-ties.
Use copper wire, not aluminum. Copper is a much harsher surface for the virus to survive on compared to aluminum.
旖丁 folded aluminum foil also
Also the bottom on an aluminum baking pan cut into 1/2"x3 1/2" strips works well for a nose piece

AWESOME!!! THANK YOU!!!!!!!
Did you buy hepa vacuum bags? Or you have another source for hepa filters? Thx.
Where and how do you order the hepa bag? It seems that buying a bunch of vacuum cleaner bags would get expensive therefore people wouldnt be able to make very many. Can you order hepa by the sheets or yard from anywhere?
@@amyackard2083 , I ordered bags from Amazon. You can buy exactly what was shown in the video - 2 filters per unit. I looked around and found another brand that offers 9 filters for just $2 more. "EnviroCare Replacement Micro Filtration Vacuum Cleaner Dust Bags for Hoover Windtunnel Upright Type Y, 9 Pack". Get the elastic and pipe cleaners from Amazon as well.
@@MsDonnaree , Amazon - "EnviroCare Replacement Micro Filtration Vacuum Cleaner Dust Bags for Hoover Windtunnel Upright Type Y, 9 Pack" I think they were about $2 more than the brand shown in the video but that was only 2 per pkg. Same filteration level! Same size! I also got the pipe cleaners and elastic from the same source. AND, you make four masks from each filter. Not a lot of waste.
I'm using a different filter but think this is the best pattern I have seen
That’s the point. So many people don’t research or check facts. Just wanted to get people thinking. And a vacuum cleaner company was called and they said that some filtering material being used in vacuums, heaters etc. have fibers in them that are dangerous. So check with the manufacturer of filters you are or want to use. Some are dangerous!
It's so true! People DON'T do research or check facts. That's why there are so many beliefs about what truly happens at death. Ecclesiastes 9:5 says the dead know nothing at all (they do not live on or are not suffering), but that they will receive a resurrection at a later time (Acts 24:15) If people would research instead of blindly believe what they are taught, then people could have real hope and true comfort. :)

thank you for this video. so many DIY's coming out on how to make them not understanding the basic science behind them! Now I can share this to help educate people!
2 layer Cotton masks and paper towels have actually been shown to be quite effective for civil use against novel corona virus.
For communities to wear masks is more about protecting others than it is about protecting yourself. Since the droplets and sprays that contain the virus can't easily escape through a mask, you're protecting others. But if people with corona are ignoring it, masks will be less effective for the rest of us.
Please don't share this, the materials used are unsafe for humans to inhale
Thank you so much for what you are doing to help the people!!
Best, safe and healthiest homemade facemask design!
This is what I have recently learned directly from Hoover customer care:
"Our vacuum bags have only been designed and tested for use in vacuum cleaners. Unfortunately, we cannot recommend for people to turn vacuum bags into makeshift face masks since this could give users a false
sense of security and potentially put them at risk.
Vacuum cleaners mechanically create a condition that facilitates effective filtration through the vacuum bag, but humans are unable to create this condition.
Therefore, these types of masks cannot provide the appropriate filtration and would only provide minimal protection.
With that being said, we are partnering with suppliers that have an expertise, volunteering resources, and redirecting vacuum bag materials that can be used to manufacture face masks to assist in the fight against COVID-19.
This is the best way we can currently help, and we will continue to look for ways to assist.
TY. JSGOLOM
I read in that comment that they are working on making masks, and we should wait to purchase them and pay thru the nose. These bags are perfectly fine to use for this purpose. If it was a serious health hazard, they would be required by law to give all the details. Notice they did NOT do that!!! The 'risk' they mention is the risk to contract CV, but even the 'minimal protection' (in their opinion) the bags provide is better than NO protection. These bags do not contain fiberglass and do not prevent the user from breathing...... therefore I'll be using them. What happened to common sense?????????????????????????? Come on people..... THINK
In other news, furniture maker has not tested whether your night stand will work for dashing an average-sized intruder over the head.
Of course the tell you that its called CYA
HEPA bags are made of glass microfibers. They're made for vacuum cleaners, not face masks!
As far as I know, it is not recommended the HEPA material to be in contact with one's face, even less to breath through it.
Way batter to have a cotton mask made of two stitched pieces forming a pouch; in the interior of the pouch / filter pocket one should have the HEPA which may be dispensed after every use and the cotton mask washed on a daily basis.
A 5 HEPA hoover bags pack would be sufficient for one person for roughly 60-ish days / two months.
Actually for your model, you would have room for five masks profiles on the hose connector side if you would have on the longitudinal left and right sides the profiles in the mirror - or one the trapezoid base towards the centre, with then second with the base towards the exterior, six on the opposing bag's side.
Yeah, someone else said these are made from glass which can cause serious lung issues.

Bill Morgan exactly! I work in healthcare and this is def off.
Robert Wahnee no clue - I just made ten of these out of nilfisk bags made out of microfibres material - they feel and smell the same as the kn95 masks I got from China.
These masks are better than the cheap surgical ones and you can make them for 50 cents a pop.
Choose the right bag - I just made ten out of a decent material bag - and as the man said better than nothing.
Where is you idea for an alternative mask?
Yes another doctor is saying the exact same thing that they are dangerous
@@robertwahnee5236 Said by someone who doesn't know what he is talking about. Get a bag and try it. The doctor said he wore one around the house and it was fine. Breathing effort is not much different than an N95 mask.
You need to be careful about cutting elastic down the middle like she shows here, because a lot of elastic will start to unravel when cut like that. It's better to purchase the correct size of elastic. I've been sewing for over 40 years and have tons of experience sewing with elastic.
I agree with you on this. The reality is, elastic seems to be the 'new' toilet paper, you can't hardly find 1/8" or 1/4" which is preferred (and what can be found has gotten expensive from what I hear) ......
Hes probably not wearing him for that long also, since his wife is making him multiples.
She is doing the mask with the materials she already has. Quarantine guys.... In fact, in my country we are in a lockdown so you can't buy the elastics, only essential business are open.
JAYME CLARK Where is a good place to get elastic?
Bettina Cecilia Silveira Bettina where are you at may I ask. I wished the Iowa governor would do that as staying home for a month is the only thing going to stop this world wide!
Thank you Mrs Southworth.
A fabulous idea and i successfully made 2, thank you. Unfortunately I had to take it off after around 10 minutes, my face was swelling up big time. I had to have Hydrocortisone ointment prescribed. So I have now gone back to the lined pocketed cotton ones I made. The "filters" that go into the masks i have made are non woven interfacing. Another idea for the filter to fit into the pocket is to cut off the outside layer of a new disposable nappy but throw it away before you wash the mask after each wear. I had to use whatever I could find at home to make these as only food and animal feed stores and petrol stations are open here in Ireland. We are still in lockdown.

@Drake Pierre Hey, Drake. Great self-promotion!!! For $8.00 you can purchase something you already have around the house!!! So, you don't even put interfacing inside your "masks?" These are no better than your average jock strap. If you don't already have a medical-grade mask to put between the two layers of your mask, then why bother? There are so many sewers that are making better masks in great colors and patterns and GIVING them away all across the country to anyone in the country! Don't be fooled. Your thread bare sheets or towels are 100% cotton, so that doesn't mean anything.

The cotton masks in testing still block about 50-70% of the particles the size of covid 19 depending on the weave of the fabric and can be sanitized by the hospital on arrival and sanitized and re used. So if all people have available is the cotton people should still keep making those as a next step resort when these vacuum bag ones run out. It is better than nothing and if sewn correctly will have a better seal to the face than "bandanas and scarves" which the cdc is recommending as last resorts when masks run out
Carissa Agurkis,
For all people that love 800 cotton thread count, time to cut your Egyptian cotton sheets and make masks...😜
@geeksquad smarty the virus is .1 microns. But the carrier droplets from coughs and sneezes are significantly larger. Wearing a fabric mask helps protect those around you by blocking the disbursement of these particles. It doesn't nec project the wearer from the virus.
I've been told that as long as the hospitals have some masks the 'real' n95's go to the Cov-19 staff and the cotton ones are used by other nurses taking care of the rest of the patients, so the cotton ones should work and still help out alot
People can insert a hepa filter section inside the cotton mask
@geeksquad smarty that's good info.
What part am I incorrect about?
Great stuff. I would suggest just one improvement. The major issue about producing proper p3 (N99,99) masks is about using microsuturing or gluing. The holes in the fabric at the suture line are the weak points of such DIY masks and if you are to use it in the presence of infected person rather than on the street I would make sure, that additional layer of nonporous material is glued to the suture line. Just a narrow piece of thin flexible plastic could be glued over the suture line on the outside with the glue you used for the nose wire (I am a physician myself so that is not out of blue suggestion).
BOlesław Nowikowski > Excellent idea. And FYI: Those nicer sewing machines, like this demonstrator is using, have an adjustment lever to bring those stitches way down to super-tiny. I bet it would be possible to get a very-fine sewing machine needle too...
boomer1954ful you don’t need either of those things just a narrow piece of thin flexible plastic glued over the suture line on the outside, same glue used on the nose line as the prior commenter said.
If you are a physician then start working with a company to start making electrostatic face masks.

You can use wonder clips to clamp the pieces together while sewing. They won’t puncture the mask pieces.
Like the quilt clips?
Camaj Fiber Arts I’m not a quitter but yes, I think they’re also called quilt clips.
Kathy Cultice I use clamps all the time in the leather studio; saddle leather is too thick to pin! I also use glue for a hearing leather so it won’t move before I take it to my saddle stitcher.
Any clip will do even clothes pins work if need be. Go slow if you using a sewing machine so the material stays aligned better
Another great idea. I use wonder weights, but they are difficult to buy anymore.
I ordered a few of these vacuum bags to keep just Incase. I’m going to use them as liners in my sons masks as he is autistic and cannot tolerate most masks. Also he has asthma so we have been as careful as possible and in full lock down the entire time. Thank your wife for me!! She is incredibly clever for coming up with this design and I’ll definitely be making a few sets with the rest for the nurses and Drs at our family doctors office. Hopefully they won’t be needed but it better to be prepared. Thanks again!

You're bless to have a loving wife.You better cherish her love.
Most of the cotton masks being made have a filter pocket. You can cut one piece of HEPA filter to go inside the pocket, using less material and no extra sewing.
Thats what I was thinking. I made a 2 layer mask just so I could put a piece of filter in it.
That's what I was planning to do as well
Me too. I'm putting a piece inside my bandana. I do not have the money to buy all those materials & I do not have a sewing machine.

good luck finding this elastic as i have looked everywhere to find it so my friends could make masks.
Yeah, me too. Then yesterday I was in Winco and picked up a four pack of elastic head bands in the hair accessories aisle.. They're about a half inch or so. Otherwise I was going to use the elastic in underwear, but this way I don't have to walk around with "JOE BOXERS" on my face, lol.
I ordered some from ebay, it never arrived. When I asked what's up I was issued a refund. :(
I'm making masks and the ladies at walmart said everywhere is sold out of elastic right now. So I got those skinny headbands I see women at the gym wearing for their hair; I just cut one of them in half and sew them together lengthwise to make the length I need and since it's for hair, it won't snag the hair like elastic does.

Thank you for this wonderful video. It is the only time I have seen a mask I want to make because it is safe. Thank you again.
Brilliant idea! This said, the effect of these masks might be lower than 99%, because a vacumcleaner has a Hepa-filter in addition to the bag which gives the high effect. The seams from the sewingmachine is a weak point of the mask, and it might be a solution to cover the seams with scotch. I wish you all the best!
Couldn't you use a waxed on type thread that seals a lil better when heated once?....🤔
Do not be discouraged, be making your cotton masks, just include an opening so that a hepa filter can be inserted in the opening. Simple as that.
NO .. because the virus particles takes the path of least resistance and it will basically go around that hepa insert.
@@danc2014 Many of the cloth masks a snug enough to not allow particles to go around the filter. And cloth is better than nothing.
@C. Lord Ohh wooowww! 😭😷
that may be true but in the process of trying to travel the path of least resistance, it may get snagged in fibers before it can arrive at the nose.
@C. Lord do they, hmmm?
This doctor is right in suggesting the Hoover AH10040 for the mask (or same fabric different size big if unavailable). For those people concerned about the vacuum cleaner bags having fiberglass, make sure your mask is made from the HEPA Fiiltrete bag, like the one his wife uses. While this 3M fabric was manufactured for Air filtering, rather than masks, here is what the website says, under the Title "Filtrete":
3. Specialized filter media allows for optimum airflow. Unlike fiberglass filters, Filtrete Filters help protect your heating and cooling system and improve your indoor air quality by cleaning the air as it passes through the filter. This material is a synthetic possibly like polypropylene.
So, there is NO fiberglass in this one. Personally I think this fabric is GREAT covered by layers of cotton for prolonging the life of the mask filter material
Must realize the most critical aspect of wearing any mask is close facial conformity to the facial anatomy, the cloth margins if the filter is enclosed in cotton fabric and certainly sewing creates perforations which leak, obviating this seal as created with ultrafrequency welding not possiible with this deesign. While I understand the intent they would not meet vertfication standards or grades and could present legal liability if failure ensued. I also note this physician is not well trained in the requirements of aseptic techniques, the most important of which would be mask leak from poor fit due to his beard! I do appreciate he and his wifes valiant attempts, perhaps marginally acceptable, and sorry for deflating the balloon but I am a retired physician with 45 years infection control experience with all varieties of masks and asepsis procedures and have some concern with the rrpresentation of this application!

What a great idea this wonderful woman has had.
Thank you 🙏🏻
The design layout of your mask has the front using the factory seal, which is great. However, the sides having been sewn, has now introduced holes into the mask. It would probably be a good idea to run a bead of the hot glue along the stitches to seal them up.
or bees wax, melted candle wax at a pinch.
@@briandunn2807 But would wax crack and fall off?
@@LisaPearlify not necessarily
That was my thought... but if you hot glue it then sew it ?
@@LisaPearlify depends on how applied, warmed and rubbed over the seals/ seams, I do not know which would be the best way, but looking at all available ideas, because things are going to get very scarce the longer this goes on.
