Mildly Interesting

This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.

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

I read that as "our-SER-uh-pee" at first. I now have a new adjective.

Is that a portmanteau made from "arse" and "therapy"? Because I might be interested.

have you heard of the Ikea Starkvind filters? they're a bit smaller but you can tape together as many as you want

Theres a way i bet. You just need the filter dimensions to match the fan on one axis.

You can make them yourself using felt, wire and glue. Might not be exactly as effective but better than nothing.
