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.

      I’m going to start talking in vague terms about my own designs for a “Corsi-Rosenthal Box” when I want to sound smart.

      It’ll be great if anyone bothers to look it up.

        “My Corsi-Rosenthal Box is designed to efficiently accelerate particles inwards. The particles are then ‘captured’ using a special filtering technique, and separated from the air molecules which are allowed through.”
