Encapsulated in Rapid Adsorption Media, the Activated Carbon removes Chemicals, VOC’s, bio effluents and other objectionable odors. Unique to activated carbon filters, the encapsulation media acts as a pre-filter and prevents carbon particles from loading downstream antimicrobial and HEPA filters. The Peak Series Activated Carbon filters have an Ozone 5 rating with greater than 50% Ozone removal efficiency.
