CleanAirKits

CleanAirKits started in 2022 as an online community of engineers from around the world experimenting with PC fan-powered Corsi-Rosenthal boxes. Their goal was to design a solution that could offer air cleaning in a quiet, cheap and efficient way to keep classrooms’ air clean and safe after mask mandates were dropped.

The CleanAirKits hand-assembles and ships all their air purifiers from their headquarters in Missouri, United States. Their devices are built as snap-together kits that combine powerful (and whisper quiet) PC fans with readily available MERV 13 HVAC filters and smaller HEPA H11 cylindrical filters.

Prices for CleanAirKits air purifiers range from $189 to $499.
