The X-2700 HEPA air scrubber effectively removes contaminants such as bacteria, allergens, mold and sub-micron sized dust with its advanced 3 stage filtration technology. The first stage of filtration is a washable Nylon Mesh Filter (NFS13) that traps larger matter and prolongs the life of the subsequent filters. The second stage of filtration is a high capacity Pleated Media Filter (PF13) that traps smaller particulates and aides in preventing cross contamination. The final stage of filtration is a thick HEPA Filter (HEPA65-33) that captures particulate matter as small as 0.3 microns with 99.97% Efficiency. An integrated indicator light illuminates when these filters need to be checked for air flow restrictions which might require cleaning or changing. Color: Blue and black.
