Here’s another sweet spot for DIY Air Purifiers: super quiet 40dB kid magnet, sweet hum note, pulsing nighttime glow, ~ 200 CADR airflow matching medium HEPAs, just 25 Watts and ~$120 in parts. #CorsiRosenthalBox #WomenInSTEM #COVIDisAirborne Image Kudos @CRBoxKits, @robwiss, @Mw_ottawa for pioneering PC fan #CorsiRosenthalBox builds. @kprather, @JimRosenthal4, @CorsIAQ maybe your freshman engineering class can formally characterize the airflow? Can also stand upright with 10 fans (5 each tall side) for 400-500 CADR? Image
