The Filters Fast® FF20255X6673M8 compatible air filter replaces the Lennox X6673 and features a MERV 8 rating that is effective in the capture of dust, pollen, and pet dander down to 3 microns in size. 5-inch air filters offer superior dirt holding for a more effective capture of airborne contaminants between change outs. The greater surface area of the pleated design can also decrease energy bills when compared to smaller filters that become clogged with dirt and debris sooner. The Filters Fast® FF20255X6673M8 compatible is a less expensive alternative to OEM air filters without having to sacrifice household air quality.
