How do air filters work?

[@moochify]

*The two units I purchased work great. **Fastly.Cool** and air purifier perfectly this machine The filters are definitely collecting dust! I contacted Levoit directly for a minor issue, and received exceptional customer service!*

This video is perfection. Great job.

It reminds me of the counter-intuitive way that size-exclusion chromatography works. It's sometimes called "gel filtration" but I find that more confusing. Basically if you pass a solution of different proteins through a size exclusion column, the big ones come out first and the smaller ones come out last. This is because the smaller ones takes the long narrow winding paths through the porous beads, but the bigger ones don't.

Thanks for the video. I hope it helps educate people.

[@QuebecPrepperthenewboydesbois]

It did for me!

[@selenesari8886]

Very well explained, great video!

[@demonsrexis]

A well made definitive video clip, keep it up.

Hi, thanks for your useful information. I have a request, may I have permission to translate your video in Persian(Farsi) or subtitle it??

[@riskbites]

Please do

[@gigglysamentz2021]

Very interesting ! I had no idea.

[@hvacmensch]

impingement + Brownian motion are the mechanisms for air cleaning with pleated air filters. There are other methods as well.

Really nice non-technical explanation of particle filtration by interception, impaction, and diffusion (Brownian motion). Might be neat to do an extended version with a bit more physics as well as cover other mechanisms, such as sedimentation and electrostatic precipitation.

[@riskbites]

Thanks - yes, this was primarily made as an example of using whiteboard video techniques, hence the shortness. Lots of scope for expanding this out!

More videos please!! I subscribed after watching your battery video.

The nice thing about physics, is that physics can't lie.

Great vid

[@hehe2419]

Great video, the demonstration and wording were very helpful for me to understand. Based on your knowledge of air filters, in your opinion what air filters do you know of that do a great job in removing medium size particles?

[@tomaslaurenfilm]

Why does not air filters eliminate odors? Aren't odors small enough to have the Brownian motion?

[@JurWiersema]

Cool!

[@Nonume]

Is this the same for 0,22 micras water filters? I've always wondered how can a 0,22 micrometer filter could be a sterilizing filter if there are bacteria smaller than 0,22!

[@riskbites]

The same mechanisms apply to water filters, but the particle sizes they apply to are quite different due to the density and behavior of water as a liquid. In the case of bacteria removal, most bacteria are larger than 0.2 micrometers, but water filters will still remove particles smaller than this.

can you please send the words that you said?

[@tayls444]

How did I end up here

[@nwt689]

Is this video stolen? Because there is a same video uploaded 2 years before this vid

[@riskbites]

Not by me - I'm the creator, and it draws on my professional expertise. The same video does appear elsewhere though, and in a couple of forms (it was used as part of a video creation workshop)

[@1Skeptik1]

Interesting! The big question: Can we consider cheap imported cloth masks an effective filter (capture) an airborne agent measuring 5 millionths of an inch (C-19)? I think not. Experts - educate me. Cheers

Haha no wonder i can't crank my bike cuz my airl filter covered with rugby and my exhaust well yeah the big rock stuck inside it pretty much.

[@EM8844]

horrible choice of music. but man you draw well

[@riskbites]

Ha, thanks ... I think! And of course, there's an easy solution to the music - turn the volume down and whack the subtitles on! ;)

[@geraldjinx]

@@riskbites That sounds like the "Ozentic" drug ad LOL

[@angelacoppola7919]

I'm sitting in front of my air filter with an N95 because the air quality is over 300 AQI. I could do without the cutesy music - handclaps and "oh-oh-ooh-oh-oh". It feels like the end of the world here in California.

[@kimienick6721]

Its same on LUNG CASES, when your lung cannot flow the air you will get less OXYGEN, same on engine too... Your engines CANNOT START!!!!! due not have enough enter inside, even have the PERFORMANCE will drop half... Human also... When your oxygen not enough all drop low.... THAT HOW AIR FILTER WORK!!!

[@AbdulSami-td6pk]

In short - Urs nose hair s Ur filter that's much better nd Free :)
