COVID-19 (Coronavirus)

Can Austin Air Cleaner capture Coronavirus?

An air purifier equipped with a medical-grade HEPA (high-efficiency particulate air)-rated filter can technically capture a portion of airborne virus-sized particles (see NASA study). Once trapped, viruses cannot multiply on their own or remain infectious for long. The HEGA cloth used in their Allergy Machine, Baby's Breath, and Bedroom Machine is also antimicrobial. 

Please remember - NO air purifier can completely protect you from a virus.
