FDA granted 510(k) Class II Medical Device Clearance for Air Pro RX, an air purifier intended for medical purposes to destroy bacteria & viruses in the air.
Air Pro RX also satisfies performance criteria outlined in FDA guidance for use in helping to destroy SARS-CoV-2, the COVID-19 virus.
Same FDA clearance as RxAir.
By the way... THEY ARE IN PRODUCTION! Want more? I can find others.
Then there are the UVC light room sanitizing units. They "clean" a room in minutes. And seem to be what hospitals, hotels etc want.
MUCH better than a air purifier with a UV light in it which takes forever to filter the air in a room - and DOES NOTHING about virus contaminated surfaces!
