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
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!
dont worry they mix with the microplastics down there
I mean, yes.
But like, they have to, without the filter.
Some dirt gets pushed out and sum just stays
