Clearing smoke with an Air purifier. Which is fastest, quietest?

Testing the dreo air purifier against other methods to see which clears smoke from the air the fastest while graphing particulate levels in the air with a particle sensor.

Tested the Dreo air purifier, Dyson purifier cool, fan with filter, a dust collector
and a homemade one.

I don't mind sponsored videos as long as I learn something. Being transparent about the sponsorship is another boon I appreciate. Excellent closing advice to digital makers! The jury's still out on the long-term health effects of VOCs emitted by melting 3D printing filaments, so it's better safe than sorry.

One thing I noticed was missing from your experiments was a comparison against a no-fan mode, to see how the "pollution" behaved with no air cleaning.

[LukeTheJoker]

Love it when a sponsors product actually is tested properly and holds up, very much worth the effort!

As a guy with LOTS of box fans already, it'd be really interesting to see a test of which MERV rating is optimal for a box fan filter for the smallest particles from wood, 3dprinting, etc. I have to say this is an excellent way of presenting sponsored content. Well done.

3:54 I love how a simple box fan with a filter is better than the Dyson!

This video, and another, convinced me to make air filters with a box fan and two 20 x 20 furnace filters. I have one expensive filter that is rated for smoke sandwiched between the fan and a cheaper filter that catches the big stuff. Ideally that arrangement prolongs the life of the expensive filters. I am running two of these in my home while we're socked in with smoke from wildfires.

To be totally scienktific you should have a control where you do nothing just to see how quick the stuff settles (if at all). Box fan with filter FTW based on cost/effectiveness IMHO.

[rrproclaim]

In all of this testing, I'm curious what the decay rate was with no filtering? How much does the air quality naturally improve over time compared to the various air cleaners?

[vaxjoaberg]

This is an excellent video. I feel like I learned a bunch about air filtering systems. And I'm motivated to tape a filter to a box fan to clean up the dusty air in my house now. I'm surprised at how well that actually worked!

There’s something so satisfying about watching you do all these test. Thank you sir I appreciate all your hard work.

[MattKnowsThat]

I think you should’ve done a control test with dirty air for a while with no filter running at all. That would baseline the natural air leakage of the room and the particles settling out naturally.

I winced a bit with the "product placement aspect" but the one thing I've learned is; "you talk, I listen"... GR8T VIDEO. Super Dreo Product. Thank for your time. Cheers.

[kristiandawe]

The Dyson looks mighty high tech, but I love the homemade air cleaner better, it looks sweet and still highly efficient.

[Sceme]

You actually manage to make sponsored content interesting. Bravo, well done! Also props for Dreo for being so brave as to let you put their product to the test.

[nerdgeekdc]

A couple notes about the homemade filters:
1. For best performance you may want to tape the edges of the furnace filter so there's no leakage.
2. A slightly dirty filter will filter better than a new one until it's too dirty.

[DEtchells]

Very well done, and as others have said, there’s no problem with openly-disclosed sponsored videos with objective test methodology.

=> Big props for the log plots! It made it so easy to translate the curves into rates. I was well-familiar with log plotting, but I still learned something :-)

[BernardSandler]

This was absolutely fascinating. Fast, informative. Your comments about the sources of dust at the end of the video make so much sense, but I hadn't thought about it before.

[viqq]

Thank you I had no idea that all those things you mentioned actually rise the particle count. I have literally been using my purifiers wrong or at wrong time. Thanks again Matthias for very informational video.

[MattButzen]

The way you approach sponsorships is great for everyone involved in my opinion.
The data visualizations are especially appreciated

[MattTrevett]

This was a great ad for box fan with a filter duct-taped to it.
