The Lennox X6664 MERV 11 Air Filter Replacement is a replacement air filter for the Lennox PCO-12C PureAir air cleaner. This pleated air filter features a MERV 11 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.
Lennox recommends that you change this PCO-12C filter every 6 months in standard home environments in order to achieve the highest performance from your PureAir unit.
