With annual filter replacement, you help your system operate at its best and maintain high-quality indoor air. Remove contaminants from your home with Lennox X8790 air filters in your PureAir system. The filter removes more than 95% of the particles and bioaerosols (dander, pollen, bacteria, molds, spores, etc.) as they flow through the PCO. The MERV rating of a filter describes the size of the holes in the filter that allow air to pass through. The higher the MERV rating, the smaller the holes in the filter providing enhanced filtration.
