btw, I converted mine to PC fans, and they are SO QUIET. My family hates the sound of fans, and they can't even tell the box I usually have on is running... keeps the AQI usually sub 10 (working harder to keep up this week though, so more like 15).

If you are not the DIY type, this kit has everything you need for a PC fan Corsi Rosenthal (from CleanAirKits), you have to also buy the filters.

Corsi Rosenthal Box | Clean Air Kits

Clean Air Kits are super efficient air purifiers built simply from banks of silent PC pressure fans and 3M Filtrete virus+allergen filters. Quiet enough to leave on always, powerful enough to protect from airborne pathogens like Flu, RSV, Strep, & Covid-19

Great design, and great post @trendless !

Thank you for all the part numbers and pictures, descriptions, etc.

After making 2 of the 1st generation Corsi-Rosenthal boxes, the next ones I build will use your design.

Slick looking, efficient, replaceable filters, and quiet.

Spotted this cool Canadian-made air purifier: North Box Systems builds quiet, energy-efficient units using PC fans + MERV-13 filters. Think: Corsi-Rosenthal box, but sleeker. Great for wildfire smoke & allergens. πŸ‡¨πŸ‡¦πŸŒ€
