AirFilters.com With poor outdoor air ventilation, it is necessary to have extra protection against indoor air pollution. Air purifiers are great for keeping the air around you clean of harmful pollutants, but they can become clogged easily. That's why you need an air purifier pre-filter. Pre-filters remove large particulates that easily clog a filter, increasing the main filter's performance and helping it to last longer. This particular product is a replacement pre-filter for BionaireA(R) model BAPF825 and HolmesA(R) HAP422. It uses a foam filtration media to remove large particulates like dust, pet dander, mold, and pollen.
