*Laboratory testing demonstrated 99.99% reduction of aerosols carrying MS2. Copies of the full test reports are available upon request.
** Air Changes per Hour (ACH) is calcualted based on a 500ft2 room with an 8ft high ceiling (4,000ft3).
ACH = (CFM x 60) / the room’s cubic footage.
CFM is a unit’s cubic feet of air flow per minute.
