The Atmosphere Sky Air Treatment System uses a three-stage filtration process for maximum effectiveness. This second-stage HEPA filter effectively eliminates a variety of airborne contaminants, including dust, allergens, viruses, bacteria and pollens. Advanced design offers better-than standard HEPA performance – removing 99.99% of particles as small as 0.0024 µm (microns). Standard US-HEPA filters removing 99.97% no smaller than 0.3 µm (microns).
