The Lennox HC X6664 MERV 10 Air Filter Replacement is a replacement air filter for the Lennox PCO-12C PureAir air cleaner. This pleated air filter features a MERV 10 rating and can trap airborne particulates down to as small as 0.3 microns for an increase in indoor air quality. A higher MERV rating results in better filter performance and a higher capture of particulates.
