What half face respirator do you use tho?
@@kevinblaze3071 A distraction? They really told you that?
Me: 3M Versaflo
You can get an adapter for those n95 filters so you dont have to use them with the vapour filter at the same time. You can also get a pink plastic case that has a reduced sized aperture.
With COVID-19 and the shortage of filters for the half masks as well as N95 masks, use a surgical mask to cover either the filters of a half mask respirator or the whole mask on a N95. Extra barrier of protection.

Bullshit. Surgical masks offer zero protection for the wearer.
@@Rondoggy67 The surgical mask overlay is for protecting the industrial filter cartridge from absorbing splashes and propelled droplets since surgical masks are hydrophobic.
@@Rondoggy67 The exhale valve still must be covered
The first filter you said to throw away after exposure. The bit you said "Removes with difficulty", can be and is meant to be removed so the white particulate filter can just be replaced on it's own.
The filter part number is 3m 5n11 and they can still be found if you look around.
Thanks for your service - Steve
d1v1s1onby0 Yes I have removed them. The package often comes with two pre-filters in it for just that purpose. But compared to the 6035/6038/7093 enclosed particulate filters, they are just not as safe for our purposes and I would only use them as a last resort, given how tricky they are to clean.
5n11 cost about $18usd for a box of 10(5 pairs). Much cheaper to stock them as single use vs 2138

In some countries you can find 7093 or 7093c filters. Those are p100 and should do the job without mayor issues. Those filters have plastic housing too.
This is fabulous! Thank you for this video. Love the 7500 series med half & been a 3m fan for decades. Stay safe!
Great review. I'm a physician who does intervention on Covid patients and I use the 7500 series 3M half mask. I use dish soap and water soak and then Honeywell refresher wipes. Stay safe.
@Fact Checker There is a filter on the exhale valve that should reduce the risk of contamination but only in part.
Fact Checker Not correct. The filters are 99.97% effective and if you don’t have COVID you can’t pass it on.
Hi thanks for sharing. Here in Scotland there’s quite a lot of confusion re so called ‘P3RD’ filters where the ref to ‘RD’ remains unclear in the context of whether they offer less protection from Covid-19 compared to P3 filters. The ones your using don’t appear to state ‘RD’ so I’ve got some added work to do to see whether they’re effective. Keep up the good work abs stay safe.
John
thank you SO much for explaining this and clear up the confusion. excellent video!
I have bad dust allergies and have been using respirators for years. 3m is very middle of the road, bit like a basic Ford car. There are classier makes with less breathing resistance. Appreciating all doctors.
Make and model please. I am afraid of masks causing a open lesions that could transmit, or is the lung's the only way?
@@jacobclark89 sundstrom, Scott, the stuff from Europe is very good. Sundstrom sr 200, eBay is good..
Nice, over here in NZ we are not provided with this level of protection. This has helped with my personal purchase. Thank you very much.
It is rather easy to trace the filter or gas cartridge onto a piece of fabric, paper towel or other breathable material. Then cut it to get a pre-prefilter to use as an outer layer. I used some non-woven from old furniture after hand washing and drying it, it seems to repel water droplets, it did not get at all wet when I was wearing the mask outside and it rained. It also helps to make the filters last longer, since it catches the larger dust particles. since it is not the primary filter it is OK to wash and disinfect it by whatever method.
Thank you for this information. I have not seen any other information on mask and filters. I really needed this. Again thank you from Miami FL. God bless
Edgar Santiago You’re very welcome.

Our Department here in Queensland has these but we are planning on cleaning the the mask filters in-situ, while still wearing it, waiting for it to dry thoroughly, then remove, with a spotter checking coverage. I feel that this reduces the risk of contamination of the inlet ports during the removal of the filter cartridges. What are your thoughts? DM me if you like or email. Thank for the great video - saves me making one! Stay safe.
Are you wearing coveralls as well? I work at a different department in Sydney. We appear to be going down the surgical gown/balaclava route for neck coverage. At what point are you cleaning and wiping down the mask? With the coverall still on?
Michael Tobin We are using gown/balaclava or the coveralls (being careful to ensure hood doesn’t contaminate your back when removed). What we will be using will be based on what’s available I think as we’re running out of everything. The respirator is cleaned as the last step, while still on, using antiviral wipes (eg. Clinell wipes) in front of a mirror to ensure good coverage. We’re using sealed cartridge filters and not removing them, just cleaning all external accessible surfaces. So far so good.
Hi Michael (again) and nice to meet you Paul. I would not recommend a simple wipe if you have been involved in directly intubating a covid patient. But if you were just wearing it for general use while transporting a patient or in an ED red zone, perhaps it might be okay. I couldn’t say. Here is a link to 3M’s literature on use of their respirators during an influenza pandemic www.3m.co.uk/intl/uk/ohes/segments/healthcare/(9666a)OH_ReusableTechBulletin_lft.pdf
Is it necessarily a good idea to remove them for cleaning? This could create a entry point for virus particles. Since 6035 filters last months at a time, I usually leave mine attached to the mask during cleaning, clean the whole thing, and store it in a bag.
Excellent point. I recommend a slightly different way, which is to use a suitable disinfectant to wipe down the outside surfaces, including around the cartridge interlock area before removal. Then remove the cartridges, and then wipe back side of the cartridge mating area. Put these aside to dry and for safe keeping. The half face or full face mask should be decontaminated following whatever procedure your local officials are comfortable with. You do need to clean these, as your own resperatory droplets will make the inside kinda funky. The straps also could potentially transfer the virus to other surfaces, not to mention any viral particles you had stuck to your face (but not entered into your body) can be transferred onto the mask as well.. 30ml bleach + 7.5l water, TBquat, or virkon 1% are all acceptable options. Each option has specific steps and times to follow. All require a final rinse of clean water, and then allowed to air dry.
No you must remove the filters for cleaning. You don’t have to worry about possible entry points for the virus through the filter aperture. They have static charge and could not reasonably be expected to fall off the plastic housing and into the wearer side of the filter. You must clean and decontaminate the respirator after use.
Got extremely lucky at a local hardware store, they had a respirator that actually came pre Packed with a set of these filters. Been using them since, as a nice secondary it eliminates me tossing disposable masks into the waste bin so often.

How do I measure which full-face mask fits my face? So that I won't make a mistake in ordering! Thanks!
Thanks a lot for making this video! God bless you!
Thanks for the guidance on this. I'm a dentist, I worry about exhaled air that my patients might be exposed to, so I wear a normal surgical mask under it. I use soapy water sponge to clean and then expose both sides to UVC for 5 minutes. Should be good?
Not save in the slightest. Dentistry procedures are aerosolising, often, for which you'd need maximum PPE / filtration. You should be worried about the air they contaminate and infect you. Are you really a dentist with a medical background / training in viruses / infections?
I've just ordered this filters for my work.
Doctor What about the cartridge filters series 6000 ( like 6001 6002 6003 6006) I know they are already made for gases and vapours but what about their efficiency against covid 19?? Thanks in advance
Just imagine how many lives (and paranoid nerves) saved that video!
The pink pancake shaped P100 filters are more plentiful. Perhaps what is needed is a round plastic housing to glue them into so that all that filter surface area isn't exposed.
If your wanting to add the P100 filter to the cartridge filter, you can use a GM 502 adaptor that snaps onto the face of the cartridge. It has a male bayonet fitting just like the respirator. Otherwise the P100 pancake filter attaches directly onto the respirator.
Thank you you for this vid. Very informative - from a frontliner in the Philippines
How many hours of breathing through the 2135 filters do we get until we have to replace them? 3M literature states that these disk-style particulate filters (2135/2091/2097) can be used for as long as you can comfortably breathe through them, so why do you consider them as only one-time use?
SKMatoBB Because if they are spoiled by droplets then they become an infection risk. 3M pointed that out in communication to the rep I get them from.
@@staffnsnake But that's only because of the textile nature of the filter and the fact that it's surface can't be disinfected like the other filters with a plastic surface, correct? If you don't touch it with your bare hands for the 72 hour duration for which the virus can be alive on the surface after each use, it should not pose any risk and protect you pretty much until it's clogged up by dust and other particles from the environment, right? You just have to be careful not to touch their surface, transfering the virus to your hands and then to your body through your mouth, eyes, etc.. I think it'd be pretty wasteful to just throw these filters out after each use, wouldn't it?
@@staffnsnake Why would the droplets damage the filter any more than any other particulate filter? The inside of these disk-type filters has pretty much the same structure as the replacable pads that you put underneath the cover of the plastic filter. Making the only difference between them the nature of the surface of the filter as I described in the previous comment.
SKMatoBB I guess it would depend on how soon you expect to reuse the 2138 filter. I also suspect that most hospitals would take a dim view of ever reusing any kind of fabric equipment that had been soiled by patient bodily fluids and not actively sterilised. Moreover, there are other pathogens besides SARS-CoV-2 in pharyngeal droplets. I need to stress that the whole exercise of using these 3M respirators is for while we await arrival of medical grade PAPR systems. This equipment is not the plan, it’s the fallback from the main plan.
@@staffnsnake I was talking from a public standpoint, not about hospital use per-se. Mainly about using it for shopping and other necessary activities requiring contact with other people. This is the use case that I'm considering for these filters. Do you think they'll suffice for re-use in these circumstances?
Hello doc, thank you for the informative video. Cleared a lot of my doubts.
Personally using a 3m 6200 and 6800 respirators. With P2091 p100 and N7093CN filters.
Am able to get the smell of hand sanitizers when I use them, is it normal?? Or is something wrong with the filters.
PS: I regularly do the user leak test and ensure that everything is ok.
P100 filters don't filter out vapours, so yes, you should still be able to smell ethanol through it. However, do ensure that the filter is properly screwed onto the respirator body.
No you shouldn't be able to smell anything!! I can't even smell gasoline or garbage with mine.. smoke? Nothing. N95 or P100 you should not smell or taste anything
Thank you for the informative mask videos. The more people who use their PPE porperly will help save lives in this worldwide event. I wear half a faced Drager Mask with P100 filters every day / all day (in USA). Do you or anyone know where something like a PAPR (Powered Air-Purifying Respirators), or more respirator filters, can be purchased? Everything seems to be sold out all over the internet.
Yes there is a worldwide shortage of PAPR sets, which is what led me to investigate these respirators.
@@staffnsnake , you can try ebay for paprs, new used and NEW OLD STOCK
What about the pink 3m p100 discs, are they good enough for single use protection from covid?
Most of us here in the Philippines rely on KN95 disposable masks and a ton of prayers for that remaining 5%. Hehehe
I love that!
Bro bili ka na half face respirator.
I bought a genuine 6500 mask and 7093C filters since after the taal ashfall. Then I bought a cheapo 6800 copy/clone.
Gustong gusto ng mga langgam ung 7093C filters grabe, pero ung 7093CN at least they don't eat it anymore.
Since lumala pa nga ang issue ng covid19, i saved up and bought a genuine 6800.
Nice decision. Always invest sa legit equipments. In the end nakakatipid ka. If you want legit filters just message me sir. I sell 3M 6035 pandemic filters.
@@h.cedric8157 sir where did u buy your 6800 mask? Hm?
My dad gave me his respirator and bought fresh filters, we're getting slim on N95. But my fiancee had an extra N95 and I slotted the mask in it for an added filter. Maybe overkill, but my nose and mouth is covered and I don't have to worry about my mask falling off
How difficult / easy is it to breathe with one of these on?
Hi, im a doctor working in the intensive care unit of COVID-19 patients, here in Mexico I can not find Andy 6035 filters, the only ones I can find are 7093 (purple ones), P100 protection, I have a 6800 facemark, would you think they are appropriate, and do they last 30 days ? Thanks for the videos BTW they have been very helpful in how to clean the gear and how to dispose them. @staffnsnake
HTgt2 Yes the 7093 is the North American version of the 6038 and will be fine.
staffnsnake thank you for the info! I was looking for the 6035 but here in Indonesia we only can find 7093 magenta one. Will got one for my dad to do surgeries for the positive covid19 patients.
@@staffnsnake how do i know if my mask and filter are original not fake?
@@staffnsnake sorry to be thick but could you explain why?
@@staffnsnake Please could you explain why? Sorry I don't get this.
Thank you for a meaningful and research based video. There is so much nonsense out there.
What about the 3m 7093 particulate filter? Is this a viable replacement for the 3m 6035 filter?
Good video...unfortunately 6035 is not available anywhere...alternatively we cover the aperture of the catridge or the p100 filter with a surgical mask for preventing contamination from splash ...
7093 or 7093b/c are USA equivalents , try eBay
If using alcohol for disinfecting the plastics, ethyl would be a good option as, unlike Isopropyl, it doesn't degrade the plasticst as bad, if at all. Very informational video though.
Using a steamer might be better option*
If the 3M masks are not available, see my video on adapting a snorkel mask with in-line bipap filter. Has been working great in my ED. My understanding is the same filter usually is used for days with intubated patients, so I never change my filter.
Ryan Snyder I have been looking at people do that around the world for many weeks now. How do you loosen the straps to safely doff the snorkel mask?
Ryan Snyder And there are lots of Ryan Snyders broadcasting to TH-cam. I cannot tell which one you are.
Hey Dr Ayling
We'd be very grateful if you could share your hospital decontamination policy, particularly around how you decontaminate the cartridges.
With many thanks

Eleanor Robertson Hello Eleanor, this video is not representative of any particular hospital. I work at six different hospitals. The other video I posted on my channel demonstrated 3M’s decontamination protocol for enclosed particulate cartridges and respirators. I made no claim to what any particular hospital does in the event that they purchase and control their own respirators.
I have same mask. Will the 3m 6038 filters work the same, I work close with covid19 patients
C C Yes they will.
@@staffnsnake aren't the 6038 even better than the 6035?
@@luke11986 Not for this purpose. The 6038 also filters some “nuisance gases” which are not relevant to particulate filtration.
@@staffnsnake Thank you very much for the quick reply! Wish all the best
very informative I must say. I was trying to get a 3M brand of respirator but I ended up getting a different brand which is Safety Works with a filter grade of P95/OV (Organic Vapor) Can I use it at work with CoVID patients. It is pretty similar to the first cartridge/filter that you showed. Thanks a lot. Godbless.
Adi Andre I am not a rep or an agent for 3M. I only did videos on them because that was what was available. There are other brand out there like Sundström from Sweden that some are using. One hospital in Sydney has those. So you will have to do your own research on the particulate filtering qualities of any filters you get. If you can, you should also get quantitative fit-testing done for whatever you find. The vapour filter components are not relevant to viruses or bacteria. Cheers
I'd like to chime in here for a bit. Any respirator that pressurises properly works with a P2 or P3 filter. Alternatively you can use military surplus gas masks with 40mm NATO NBC or ABEKP filters which are much more common, cheaper and effective than the type of proprietary connectors you would find on 3M type respirators. Even if the filter itself is expired it retains its particle filtering properties.
@@victigr I have seen adapters to use 3m filters on gas masks. And several other adapters for different countries gas masks to NATO standards also.
What about a 7800s 3m mask?
I use a 3M 6200 medium respirator with a pack of 2, 3m NIOSH 7093CN or 7093 P-100 Particulate filter and replace them every month or 40 hour of use. The respirator must fit tight on your face. I have a full face respirator but cannot use it because the public still cannot understand the nature of COVID 19 ( a RNA with 26000 - 32000 codes) that mutates very rapidly to adapt. It isn't the case if all of us would be infected, the question is when and for ages over 70 the mortality is at least 10 %.
This video probably saved a lot of lives
Thank you for this information. Just a question, is the 7093 filter also good for use in pandemic? Thank you very much!
Irish Valina They are the North American model number for the 6038 so they will be identical. They have different numbers because they are tested by different statutory bodies. In the case of the 7093 it is NIOSH.
Hola the 2097 its good to the covid-19? , gracias!
Where can I buy my filters anyone know a website
@@moeroberts3663 ebay has 3m 7093cn for around $30 a pair
staffnsnake thank you very much! Let's all be safe while attending to cases.
I have the half mask version with the first type of filters with p1 inscerts as I work in a medical device manufacturing company with 900 + staff. Unfortunately my employer would not allow me to use it as it requires a fit test which they were unwilling to give me. Something maybe to check before you buy one as buying up stock you can't really use isn't helpful overall I suppose.
john wickham The places I work engaged a fit-testing service. That said, use of disposable respirators also require a fit-test. Is your employer doing that? If not, then they have no right to demand you use a disposable respirator either.
As staffnsnake commented, the n95's and n100's also require fit testing- they do make them in every size, and also your fit certification is only for that one particular mask from one particular company. For example, you can't take a 3m versaflow and replace it with a 3m 1860 without 2 seperate fit tests.
Not even hospitals here in the states are doing it, as there are hundreds of registered n95' masks, and we're using what we can get our hands on. and there were NEVER fit tests here in the U.S. for KN95's, as.. well.. they were not allowed here. But their using it.
Doesn’t sound fair to me. A 3m reusable respirator is going to protect much better than the cloth masks everyone else is using
Will p3 100 filters fit in your respirators
what is the American equivalent of the 6035? they don't sell 6035 in America
7093 I think
One question though, There is a filter with number 6038 for that mask, is it helpful against covid like the 6035 one?
it's the same as the 6035 but it adds chemical filtering the 6038 weights a bit more but it still provides the same protection and P3 level of filtering
@@arangaran Thank you for the information, good sir!
Sir, CDC recommends not to use respirators with exhalation valves for sterile field as it can contaminate the sterile area. What is your opinion regarding that?
Dr. Karnav Patel This is because exhalation valves do not have filters when exhaling. It is useful to breath out more easily. So respirators with exhalation valves can protect oneself very well but are not designed to protect others or the sterile area. Its better to get a resiprator with non exhalation valves.
That is a very good point. An option could be to shut the exhalation valve with tape. My concern with that would be whether the lenses would fog up quickly in that situation? What do you think about this possibility? Cheers
th-cam.com/video/eCWb_23sHg8/w-d-xo.html
@@javierpachonalvarez5757 Exhaust valves also help fogging up less on lenses, so blocking it would increase humidity on lenses and fog them
Hey Ralph! That is my view as well. In order to avoid the fog, the solution proposed by Staffnsnake is to cover the exhalation port only with a surgical mask so that there is still some airflow allowed; However I struggle to understand how the fog wouldn't be an issue in a full face respirator with the exhalation port covered with a surgical mask, as the airflow rate coming out would still be greatly reduced/restrained....It would be great if someone with a full face respirator could actually test it to clear all doubts. Cheers
honored to be 1000th subscriber! keep up the great work!
Excellent video! Inquiry ... I get a little foggy next to an exhalation valve. Someone else happens?
The straps are a cloth elastic material . I take off my gown first. Then with new gloves grab the sides of the mask and pull out and up. I have cleaning wipes set out already and wipe it down. The straps don’t need touched.
How long can I use the 6035 filter for? There is nothing online about it? 100 hrs? 30 hrs?
Hi from Wales.. UK.. Great vid.. Sorted my confusion there.. Thanks
Couldn't you use a UVC lamp to disinfect the cloth disk filters after use?
theoretically yes. but its possible that particles went deeper into the filter fabric and might not be reached by the UVC. but UVC will surely kill off everything on the outside. if you have to reuse them, than exposing it to UVC is surely better than nothing.
I not sure if n or kn can filter the virus while inhaling but it looks like it helps to filter breathing out. But the cartridge filter systems with the correct cartridge that I have seen use a check valve that won't filter while exhaling , so it might be much better to stop the person from getting it but not spreading it , So the check valve it needs filtering the air IMO. Do you concur with my hypothesis ?
Jacob Clark It isn’t an hypothesis, it’s reality. There is no filtration or exhaled air. If you are doing anything invasive for a patient with a reusable respirator, you *must* cover the exhalation port with a standard surgical mask.

7093 Gang FOR LIFE!
I have read that the filter has to be 7093C (technical sheet of the filter). Do you have more information about de 7073
7093 works as well. But it doesn't block any smell. The 7093c blocks the virus and the smell too.
Lissmirelle VA Why would it need to be 7093C? The C model is for nuisance gas. All you need is the filter (7093 or the European version which is the 6035).
Appreciate it, even now this is still useful to me.

For healthcare workers who have issues with asthma, what respirator would you recommend? Tnx
A half face respirator with P3 filters. Whatever respirator get P3 or N100 or P100 filters for maximum protection!

@@staffnsnake thanks for the info
Hello, does it protect other people, as I read it has exhale valve, which has no filter and can put other people at risk. Some hospitals don't allow masks with valve. Any suggestions?
all types of valve respirators can be used only by healthy people (without flu symptoms and covid negative tests)
But if you are a doctor and your government/clinic/ your chief forces you to work with flu symptoms you have to minimize viral load on your organism. That can be achieved only by respirator usage. The only thing what you can invent to prevent contamination of other people is to apply surgical mask/mask respirator on the out side of the valve.
Or you can just use simple mask respirator without valve)
Hello Dr, my concern with covering the respirator exhale valve with a surgical mask is the possibility of the lenses fogging up, particularly in a full face mask respirator....what is your opinion on that?:)
@@javierpachonalvarez5757 Good evening colleague
Well, glassfogging has always been a problem in my job, even before epidemy.
Try this lifehacks
1) Try to put some saliva on your inside lense as divers use to do with there masks (I've tried but this method sucks)
2) Toothpaste. It works better but you need to grind it well
3) Try to use antifog spray (usually u can find it in ski/snowboard shops or in car cleaning chemistry/ car accessories stores)
But read the notification first. Some antifog liquids can damage plastic googles and could be put only on glass surfaces

As you say, filters are extremely scarce 😕
Good Cats - No Adverts where can I buy filters
Hello, i bought a mask with two A1P2 filters. What i want to know is if the filters are safe for covid because of the norm. It is: ENI4387 : 2004+:A1 2008.
I dont know where to confirm it elsewhere so im asking here. Really waiting for a reply. Thanks
What brand is the mask and what brand is the filter?
P2 ~= N95. N95 is USA standard, P2 is European standard.
N100/P3 are better if you can find them.
When in severe situation use CBRN by MIRA saftey there nuclear grade but $80 a pop.
I can't find these filters anywhere online. Anyone knows?? TKS!
Are P100 advertised filters similar to P2-3 filters? Would these as well be effective against corona virus?
P100 is the same as P3 and it will work well for stopping SARS-CoV-2 ; remember to do a 'fit' test to make sure there is a tight-seal on your respirator ( buy a respirator made of plastic and rubber/silicone, not a paper-type mask, then you'll get a good seal ).
How can you make sure these items are not fake buying online ? I bought number of these in feb 2020 but the respirator is starting to wear . I see the cartridges and respirators for sale online but I know there's a lot of fake stuff going around out there. I even ordered one of these off ebay and it was a fake Chinese filter and respirator
You can’t be sure, unless you buy from the website of a legit brick and mortar distributor in your country.
Hi thanks for the video. A got a question for you, the filter 3M 7093CN work for the coronavirus??? Greetings
Rodrigo Arroyo I believe the 7093 is the same as the 6038, so probably yes.
@@staffnsnake thanks for the fast reply
Greetings and be safe 😁
I am using the 7093B
P100=p3
Don’t get the 7093CN. This means it’s a Chinese version and it’s not reliable. You want to get an authentic 3M product manufactured in the US or Canada.
Can we keep the respirator in a ziploc bag after use and simply keep in it the sunlight for disinfection?
paper or non-woven fabric bags is better (breathable). Locking in the moisture means mold growing conditions, also virus lasts longer in humid environment. if using ziplock bag, add in dessicant. Silica sachets that come with shoes, handbags, you can dry at a low temp in an oven and reuse.
Follow the 3m cleaning instruction videos, it’s not hard

I am a doctor deal with covid 19 patients .. is it safe to uce 3m 7502 half face mask with 2135 filters
There is a flap on the expiratory port ot the 3M 6800... could the Corona Virus gain access on the expiratory port?
@GetEnjoy I not sure if n or kn can filter the virus while inhaling but it looks like it helps to filter breathing out. But the cartridge filter systems with the correct cartridge that I have seen use a check valve that won't filter while exhaling , so it might be much better to stop the person from getting it but not spreading it , So the check valve it needs filtering the air IMO. Do you concur with my hypothesis ?
I'm a union painter and I use these respirator mask p100 filters particulate that helps prevent from breathing asbestos and mold or even lead which are highly dangerous to the lungs so if that's what's recommended for me to wear as a professional painter to even prep the surface, so it will protect you against the Coronavirus
@@jacobclark89 Hi Jacob, the exhalation duct is not filtered. The Dr has passed on the implicit statement from the 3M sales-rep on the suitability of these filter cartridges. Not infecting others is a legitimate issue however in a hospital ward intubating Covid19 sufferers, I assume they're already infected and already experiencing high viral load, reducing the relevance of this issue, slightly, to me. On balance you'd be far better off with a respirator and these filter cartridges ( 6035 / 6038 ) as you'd know that the air you were getting was clean. If every staff member had similar there'd be a reasonable expectation of no infections, to them, via the airborne aerosolised or droplet route, I would hope. Many other PPE and other hygiene issues just as important, of course.
Does this mask protect others from your germs when you are wearing it, in other words, are your exhaled particles released into the environment?
I am chronically ill and high risk and my home health phlebotomist, who also makes rounds at local nursing homes with high COVID infection rates, entered my house wearing a full face respirator with double sided pink filters. I was initially relieved thinking I was protected but later read online that these types of masks offer only one-way protection, for the wearer, not the patient. Is this correct?
No the phlebotomist needs to cover the exhalation port with a surgical mask.
Without modification, it only protects the wearer. Which indirectly protects you, somewhat. By removing the intake and oral nasal cup valves, and pluging up the exaust valve, the exaust would be forced to exit though the filters. it woukd also make the inside of the mask become stuffy, and the visor would fog up in short order.
A (piece of) surgical mask clamped and or glued around over the exaust would probably work.
simple. this doctor shows you how to use this mask around patients by putting a surgical mask over the exhaust valve. th-cam.com/video/17hfXgJr1Hc/w-d-xo.html
If you need to protect vs all germs than exhalation vent is not good bc it contaminates sterile field. But for protection vs COVID, someone who wears a P100 respirator is very unlikely to have COVID and thus can’t pass it on
What about 5N11 and 2091 filter for covic-19 ? Answer plz

Do all filters fit all the different masks? Like do they all have the same 3 line connection u showed (im aware its not the right terminology”
Joe Luis all the 3M filters I reviewed have compatible bayonet fittings.
They're brand specific. 3m only fits 3m masks. Msa only fits msa masks, etc
how long the filter could last? should i change the p100 filter every week month or several days?
the white ones (6035) are equavelent to the 7093's in the states. They are good for the "duration of the pandemic" when used for filtering viruses and bacteria. In theory that could be a month, or two, or three. 3m doesn't say exactly, other than replace when breathing gets difficult. According to some other literature, they also have 1.8x the surface area of the discs, so I believe you probably could wear it in a non dusty enviroment for a few months. That is a big savings over the n95 disposable ( maybe I should say "used to be" disposable, now reusable) masks.The ability to seal test these over disposables are also a big plus in my book.
@@rickw4160 No, that is not true, just look on 3M's filter replacement guide, they say that each cartridge filter should be replaced after 40 hours of use.. If you need the cartridges, they have p100 99.97% filters for sale on ebay for only $32.98 right now, the model number is 3m 60923.
@@seanl764 I spoke to 3M technical support about using these respirators against COVID and they confirmed the P100 / organic vapour cartridges (model 60921) we are using are safe to use for months. The filters are being used to essentially trap aerosolized water droplets that contain the coronavirus. The water eventually evaporates from the filter and the virus dies. These filters will never clog up the way they would if you were using them to trap particles in a dusty environment. Therefore, you will not have to change the filters. Just make sure you disinfect the surface of the filter and mask after each use. These filters are better than the pure P100 disc-shaped filters which are exposed filter media. They cannot be disinfected after use and therefore can only be used once.
Sean, directly out of the 9666a OH reusable tech bulletin:
Q - For how long will a set of particulate filters last in use? A - Filters should be changed when they become clogged with particulate contaminant. The wearer can determine when this occurs as it becomes harder to breathe through the filters. The filters are designed to filter out particles in industrial conditions and in concentrations much higher than is likely to be encountered in a pandemic situation. It is therefore expected that one set of filters will cover at least one pandemic wave, after which they should be replaced for infection control reasons.

depends on which one your using, and how your using it. The filter media should be good for months in non dusty enviroments. Decontamination is the problem here. You could in theory take off the 2000 series pancake filters after every use and wait a few days- the coronavirus should be inactive by then. You can also try and purchase (or make) what they call rain shield or shower caps which create a hard outer layer on the filter, making external decontamination easier to accomplish. You would basically change filter cartridges only when you have breathing difficulty. I've used them in industral construction applications and they would last 2 weeks in concrete grinding work- pre OSHA silica rules. Now that they have the silica rules in place, I can get about 2 months out of them before It bothers me enough to change it. It should last at least a month (if not two months or more) even if your using it 8 hrs a day 7 days a week. the 2000 series is consecutive layers of decreasing pore sizes. the 7093's is a single layer (which may have decreasing pore sizes, not certain) pleated filter. They each have their pro's and cons in different enviromental situations. If your dealing with people on the daily (i.e. medical field) I'd try and get at least the 7093's or the combo p100/organic vapor style/nuisance filters. These have at least a hard outer shell that you can use a sani wipe or calvacide wipe to clean inbetween patients or breaks, etc. If its just to go food shopping, etc, the 2000 series will be more than adequate, just remember to try and not touch the filter media itself, as any viruses that are stuck on the surface can still come off, and the media have limited cleaning options.
Please reply..
As a nurse.. I'm using 3M 6200 respirator for covid19 patients..How to keep the Filter still in good quality while i'm reuse it..?? Can you give me some tips how to clean the filter after use it.. Thanks 🙏🙏
I have read that UV-C light can immobilize bacteria and viruses. I'm not in the medical profession but have had CBRN training. I took a box, lined it with Reynolds wrap. Attached a UV-C light to one of the lids. When I come home form work, I put everything I've touched in the box, close it off, turn on the light and leave it for no less then 20 minutes. I turn off the light, open the top and walk away allowing the ozone vapors to escape. Come back in 5 minutes and pull out my items, including my protective eye ware, mask, keys, wallet, etc.
Here's a videio form a DR making his box to clean masks: th-cam.com/video/P5HsKmTTa-c/w-d-xo.html

I herd millions of ppe masks have throughout Europe been ordered but Switzerland held there in customs for over a month now. This has caused basicly a traffic jam with air delivery and orders for alot of European country's.

Hey, do you have any information about filter 6075 (of course + P3 pre filter). I was wondering because it is listed as filter for hospitals and laboratories. Does it help or 6035 is better because of the inhalation area?
That filter shown here (plus pre-filter) is a vapour filter that absorbs formaldehyde among other organic vapours. So it would present the same issues as the regular paint vapour filter plus pre-filter in that it is difficult to keep clean. The 6035/6038/7093 are better because the filter is completely encased and droplet-resistant, whereas the setup you mention exposes the pre-filter to droplet contamination.
is the 7093c filter good for medical use to avoid viruses?
Up
There are not any kind of filters available on the market to cover up the exhalation port so the 3M masks can be used in sterile environments? Taping the port or using a surgical mask on top of the respirator just to cover up the exhalation port seems like a poor workaround. Given the fact this is an official combination of mask/filters for a pandemic influenza wave by 3M, I would bet there is something to complete the set for sterile environments...
I have a 3M 3500 series organic vapors respirator with noshpn95 inserts
Could it be possible to microwave the filter to kill the virus?
No. Theres no need to. It’s such a good filter you don’t need to do anything special to it.
In theory, yes, it is possible. A single model of disposable mask of similar material was tested and filtration efficiency was slightly improved even.
It is however more practical to procure multiple filters and paper bags, masks even, if you can afford it. mark the filters with numbers. likewise the multiple masks if you have them. Rotate the filters (and masks), meaning wear first number 1, next time number 2, etc. After use put in paper bag and seal it. Let 3-4+ days pass before you next use them. Longer is safer, store in dry place away, preferably locked up and out of the reach of children and the like.
Today 5/ 22 / 2020 I just got my 5400 series full face mask, sadly no filters that came with it.
I couldn't choose what filters to get for it. What can I choose what's right for it for covid 19.

Im using cartridge 7093c, sometimes i can smell food or fumes coming in, but it disappears. Is the cartridge still safe?
Fumes are a totally different thing from particulate or droplets, so yes it's fine. P100 are not supposed to filter odors.
Its too bad medical first responders can't use the 3m half or full mask, then only need to replace filters, as they last longer than the small disposable masks.
The filters last so long, even with the half mask, goggles can be used for eye protection.
Paramedics in the Fraser Valley of BC Canada came to me to buy a north 7700 half mask respirator with P100 HEPA filters. I also fit tested it for them as well

Hello, could you tell me about 7093 as an alternative to 6035? Can they be used in covid areas? I'm an anaesthetist working in close proximity.
Yes. It's the same, just for different markets because usa has different ratings to print vs outside of usa. They are the exact same cartridge though.
Unable to find the 3M 6035 or 7093 P100 cartridges (with Plastic Casing). I only have the P100 2091.
Will that help? I am a Dental Surgeon
yes I believe so, because that is a P100 filter, better than N95
I use this mask we do emergent procedures , and I dont fear exposure .. my depatment ordered 40. when we looked the covid is bad
We can all learn a lesson from that decision.
How does one choose between small medium or large respirator?
Depends on size of your face. Try a medium and go from there. Follow the 3m training videos
Hello, I've use 3M goggle+6200 half mask and fog from sweat occure really fast. Do 6800 full face mask have a same problems? Reguards.
Good kit!
You have to dampen your goggles with soap solution and let it air dry. It won't fog if you do this before every use.
Yes 7093 is good also are 2097 filters they work great if you working were nothing smells bad rotten like maintenance I would use the 2097 it blocks organic gas amongst others nasty smells and yes it's a particulate filter so it blocks covid also
Honestly look into buying air filter that will never fog up and keep you cool
mine came with filter 6001 Series ,does it Works well with covid ?thanks
Jonathan Rodriguez what type of filter. The cartridges of the 6000 series are only vapor filters and not for particles. You need the 5n11 attachment
