I recently stayed in an apartment that didnt have central air so I created a corsi-rosenthal box since the smoke from the Canadian wildfires were so bad.
After 30 days of continuous use, with very minimal periods of it being turned off, this is what the filters look like!
It’s disgusting yet also so satisfying to see the filters get darker from debris, dust, and dirt.
Edit: typos
“Corsi-Rosenthal Box” sounds like it’s some theoretical physics thought experiment, but no it’s some filters and a box fan.
Be tempted to build one of those for my shop.
TIL about the Corsi-Rosenthal Box
It is by far the best air purifier you can get for the money.
Hey, I have that same rug
It really ties the room together
I totally did not realize how much real science was behind these things. I mean this design is so simple and obvious, it seems like something I would throw together because it just looks like it “should” work. And according to the research I just read they are very efficient and effective. Super cool!!!
Now imagine that, but in your lungs. Yikes.
lungs are self cleaning, dirt just dosent stay in there it gets pushed out again by tiny moving hairs
… mostly into your stomach.
I have great news for you about what happens to the contents of the stomach!
This is a great reminder to clean my computer fans.
I’m just amazed it apparently took two people to think of taping 4 air filters together with a fan on top.
Curious why it’s not 5 filters with some little toilet paper tubes or something for legs. Was it found that the fifth filter is diminishing returns?
Sounds like an argument that would take at least two meetings and a dozen emails if this were done by a company lol.
