#CovidIsNotOver #CorsiRosenthal
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.
