Do you think Clean Air Kits Exhalaron will suck cigar smoke right into itself if I sit right next to it? Or do you think the rate at which the cigar is putting out smoke would be too fast for it to keep up? Maybe I can finally smoke cigars in the house this winter. Keep me from freezing outside. Oh and thanks for the info. Was searching for hepa purifiers and you changed my mind. Am going to build your DIY one in the next couple of months. regardless of the cigar thing.

How do you do the protien test? If the problem is mould getting out of cracks, shouldn't step 1 be run a caulking gun around top & bottom of the kickplates everywhere?

Awesome video! Thanks!

I do not understand why you discourage people on buying different/cheaper dehumidifiers? hopefully its not solely because of the referral links

light headness and realizing my place isnt well ventilated made me realize iit wouldnt hurt to inform myself on co2 levels / better ventilation

I accidentally ordered 16x25 instead of 16x30. Will this work, or will the loss of filter surface area negativity affect the performance to the point i should send them back?

Did you see Jaspr units?

Are robot vacum plus mop cleaners beneficial ?

My homes problem it is spikes in humidity we live in cold climate and small like 900 sq feet area so spikes in humidity are often from showers and cooking or even breathing at night exhaust fans are not helping I'm monitoring and see it reaching 70% humidity in bedrooms where it then condenses on cold walls. I can open a window and let the freezing air dehumidify but my concern is when I'm not around or in the middle of the night these spikes happing. Install team will not install because lack of space for ducts...

Your description has a link to 16x25x1 filters. It also has a link to an S14 fan. You might want to fix that. Hate to see people make the same mistake i did.

you need to consider cleaning the air of voc's and other gases such as formaldehyde. Particulate filters are only 1 part of the story. HEPA and CADR and CR boxes will not accomplish this.

Can you use a higher Merv rating filters for a CR box?

I love to agitate carpets 😀🧡🇦🇺

Dang! Ive been dusting for ages, by blowing onto the window sills. And i found out today, my son's allergy is for dust mites 😖Doh! I really appreciate thexe videos. I trust normal people, who give away their help like this 🥰 Doctors don't know s$*+

You had me at Hot Glue Gun. I have power tools (,a drill and jigsaw; i can use them too😆) but this looks do-able for chics😀👍. Im trying to cure my son's allergy to dust mites ,& grass seeds. Im stoked i found this info 🧡🇦🇺

Such great info nobody else has reported!

Will this work for 3d printing particals

Ok so which air cleaner is best? Please advise

I would have separated the clamshell of the fan, placed the coroplast in between, and then sandwich it back together. No need for rope.

I'm thinking of buying a PC and I'm concerned about the dust that might affect it. So I'm wondering if I should get an air purifier for my bedroom or not. Should I get one?

I use a Germguardian AC4825E. It seems to work pretty well, but, the CADR (Clean Air Delivery Rate) is low, and the filters are very hard to find, and expensive. I also have an Ionic Pro electrostatic air purifier, which also has a good first pass efficiency, but, it produces Ozone, and it needs a lot of maintenance. The problem with both of these, is that they draw air in the back, and blow it out the front. I much prefer the Corsi-Rosenthal design, because it draws air in all sides, and in my design, the bottom as well, (I used a filter underneath, and have it on a grid, spaced off the floor) then, blows the air out of the top. That creates a toroidal circulation, like a ceiling fan, placed of the floor. It's able to circulate air throughout a large room, collecting dust from every corner. I placed an annulus around the fan blade of a box fan, and closed off the corners, so there is no back flow around the top. This rig has 10X the airflow of both the other purifiers combined! I used four 20X25 Filtrete MERV 13 filters to make the sides, and a 20X20 (same specification) filter to make the bottom. It's big, it's ugly, It's loud as can be, but incredibly effective! It's amazing, when rays of sunshine beam through the windows, and you don't see a single speck of dust in the sunbeams.

Can't find that fan in Amazon in Stock. Any alternative option?

Please look into Camfil filters.. Especially CityM

That is really nice. If I was going to get nit picky, I'd replace the nylon rope with polyester rope that will never stretch. Coroplast is easily cut with a multitool and J-hook blade.

Dude....zip ties

You have to use the right peppermint, I've been told it's called Mentha piperita variegata

You have symptoms of mold toxicity. Especially if your blood pressure is elevated, you should have your home tested for mycotoxins.

.... did you remove the plastic from the filter?

Hi my dude, i dont have a large space to filter and i am also renting, however i do have ideas for something custom. How strong does a fan need to be to push though a hepa core carbon filter combo? How do i calculate this? Would i in theory be able to do this with a single or arangement of silent PC ventilators given a particular area?

Im using OREck bought it 2006 cost me 300$ supposedly it's washable filter, when i open to wash it never find much debris

I have a Bissell Air220. The HEPA filters are $25 and come with activated carbon. I replace them every six months. How often do these DIY need to be replaced, because currently on Amazon it would cost me $84 instead of $25 per six months.

4:22 why is it that the streams don't mix?

I just finished my build, so clever to hot glue the filters together I did not have a compass, I know I have one somewhere in the house... so I use whatever I had in the kitchen and found something that was 12.75 in. with a bigger hole I was able to use tye wrap and they do not catch the fan. I was afraid that the coroplast would not be strong enough but it does hold to my surprise. Thanks for showing us that

Now my indoor air is so much cleaner from the outside air that when I open the windows(especially now in winter) I always get traumatized, maybe I should build an ERV aswell

do you have a good option that's safe for parrots? and confirmed to be... as i own parrots and birds have VERY sensitive respiratory systems a lot of these products can be damaging for them (even types of heaters, cooking pans, perfumes, essential oils you name it...) and i don't know what other option to use apart from my current levoit air purifier (the refills can get pricey) let me know if there's a better option PLEASE. and thank you so much for the research on this video i appreciate it a lot!

Thanks for all you've done on these videos! Saved a lot!

I like this design! I am going to build a wood design around simething like this and sound absorbtion.

Thanks for the great information, from the very dirty Philippines.

Are the small Levoits a waste of money then? Will one of those that you made cover a 2 story house or shoould i make multiple?

What would you think about adding a UV light inside hanging down from the fan with just a base socket for the bulb to screw into?

what do you mean the brands not to worth it to buy??

I just purchased and installed a BlueAir 411i Max air purifier today in my bedroom from Amazon. I’m curious what our thoughts are of that particular one?

Might want to update the link. Link you have says it’s the 12 inch fan, but brings you to amazons 14” which is too big

I have asked questions on other sites about air purifiers and have not had any luck hearing back from the site owner. Maybe that is because my question is hard to answer, I don't know. My situation is that I live right next to a very busy road with buses, trucks, the whole works. Also, I live outside the US in a location where the clean emission standards are relatively lax. So I really have a problem. My first question is, can this car emission problem truly be improved at all in the first place with an air purifier? And next, what do you recommend I should buy of the types that you discuss here. I am not a carpenter type, I probably should not try to build my own unit. So what is next? You spoke about pre built types. Is that the way to go? I would greatly appreciate if you could help me figure out 1) can serious car exhaust pollution from outdoors be fixed inside the house with an air purifier? And 2) which model and how many units? My house is airy, not air tight. It has high ceilings. And the square footage is probably about 2500 sq ft. Thanks very much for any thoughts

Wow. Never would have thought. Awesome info.

Sorry, I don’t get it. We would never use an air filter in an open room (windows/doors open or any way for the outside air to get in). We have a number of inexpensive HEPA filter devices, and the AQI (or PM2.5 rate) drops significantly and stays low while using the device. Surely, it’s a matter of managing the room airflow, not so much the type or quality of filter?

What are your thoughts on steam cleaners (like the Dupray)? Was considering getting one for cleaning tough grime. I’m concerned it will introduce too much humidity and breed mold where I use it.

From Northern Canada here. 1950s home and no ducts. Super humid and cold here. Thanks for the dehumidifier tips. 🫶

There was a guy who pioneered a cheap DIY kit based on a study done in Beijing. IT WORKS like you said. Years later the same guy's company is selling expensive thousand dollars air purifiers too. What changed? Profit? I bought Trident air purifier which has a washable filter, no need to replace. I wonder if it actually works.

:-) Curiosity and research are good things. 👍
