The F113A is especially designed for rooms where high concentrations of particles are a problem. The two-stage air cleaner uses a prefilter and a 99.97 HEPA filter to effectively remove airborne particulates like dust, pollen, mold spores, bacteria, soot, and tobacco smoke to name a few. Maintenance is a breeze. No tools are required to open the case and replace filters. The whole process can be done in a few minutes.
Which model is best for you?
Air circulation capacity-the amount of air drawn through the filter-is measured in Air Changes per Hour (ACH). Each air change represents circulating the volume of air in the room through the air cleaner one time. All of the air in the room will not immediately be processed through the filter. However, the more air circulated through the filter, the more air cleaned.
