Features and Benefits

Our Lennox Air Filter Replacements are ideal for keeping the air in your home or office clean and fresh.  In addition to cleaning the air you breath, our air filters will extend the life of your air conditioning unit because the important parts, like the blower assembly, the heat exchanger, the cooling coil, and other inner parts will stay cleaner, operate more efficiently, last longer, use less energy, and require fewer repairs.

Our Lennox Filter Replacement uses Electrostatically charged filter media that captures airborne allergens smaller than 1 micron, including fine dust, smoke, mold, pet dander and dust mites, etc.  The filtering material will not support the development of mold, mildew, bacteria or other micro-organisms.

The Filtering media of our Lennox Filter Replacements has varying density for greater dust holding capacity.  This design traps more contaminants and pollutants while keeping the air resistance lower.


  • MERV 13 Lennox Filter Replacements are more than twice as efficient as the MERV 8 in removing contaminants and pollutants 1 micron in size.  To understand how small 1 micron is, a human hair measures 100 microns. The MERV 8,  MERV 11, and MERV 13 fit the same housing.
  • Pre-applied gasketing on the assembled filter prevents air by-pass.
  • 98% efficient filtration media.
  • High efficiency filter media collects small dust particles before they can collect on your coils.
  • No assembly required...no combs needed...filter just slides right in!
  • Each filter is individually bagged.  Use the bag to dispose of the old filter!
