AI6YR BenTrying to deal with wildfire smoke? Here's the best thing since sliced bread for massively improving the air quality in your room/apartment/house/etc.
How to build your own Corsi-Rosenthal Box
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
From Robin with Love@ai6yr oooh. This is a great idea. Those box fans are loud…worth it, but loud.
EQ@eq Yes, there's some derating of room size, but the decibels are an order quieter. Makes it possible for me to just run the filter 24/7 vs. when there's bad air quality or someone is sick. Tradeoff...
@ai6yr Think there was two kinds of PC fans too, one is better at sucking air through a filter than the other. Was too long since I played with PC fans though. Got filters on all ours to keep the dust out of the PC's.
Saw a friends 90 MHz Pentium try to flame the dust when the fan stopped working. Or might have been the 3D card. Was somewhere around Voodoo times, memory foggy. Smelled horribly. 🙂
