The Lennox Healthy Climate X6675 Carbon Clean media air filter by Lennox is designed to fit the Lennox Healthy Climate HCC20-28 air purifier.  With a MERV 16 rating, the Lennox X6675 is one of the best media filters on the market capturing viruses, bacteria, dander, pollen, dust mites, mold/fungus, and many other odor causing agents. This 20" x 25" x 5" (nominal dimensions) air filter comes with a carbon coating to trap odors in the home's conditioned space. 


It is important to note that these are genuine Lennox Healthy Climate filters which have an actual dimension of 19 3/4" x 24 3/4" x 4 3/8".  Other generic, or aftermarket filters are not designed to this actual dimension which can cause it to not seal properly reducing its ability to effectively capture airborne particles.  This genuine filter ensures a quick replacement by simply sliding the old filter out and the new filter into the cabinet. 


Lennox X6675 Benefits

  • Removes 95% of .3 micron airborne particles
  • Removes 90% of .01 microns (viruses & bacteria)
  • Hospital inpatient care and general surgery level filtration
  • Carbon coating to remove common household odors 


The #1 rated professionally installed HC16 air filtration product is now the Carbon Clean 16. This product utilizes the Lennox Healthy Climate X6675 filter for the best performance. Lennox carefully designed the X6675 Healthy Climate filter to capture the most airborne particles without causing airflow restrictions with your heating and cooling system.  With homes today becoming better insulated, your home may be holding airborne particles that continually circulate throughout your home. The Lennox X6675 will remove these particles to make sure your family is breathing healthy air. 


This Healthy Climate filter is effective in eliminating ozone from the indoor environment.  Ozone is a known lung irritant and the carbon coating found on the X6675 filter removes the ozone and allows clean, healthy oxygen to flow throughout the home. 


Not only does the filter protect your family. The Lennox X6675 air filter protects your heating and cooling system performance by ensuring only clean air is flowing through your system, helping prevent dirt and bacteria buildup that can decrease the efficiencies and overall effectiveness of your HVAC system. 


Lennox recommends replacing the X6675 furnace filter every 9 to 12 months. This can vary depending on the environment and the air quality within your home. 



*Note* - The Healthy Climate brand is the IAQ (Indoor Air Quality) brand for Lennox Industries.  The filter is a genuine Lennox X6675 media filter.


What is MERV? The Minimum Efficiency Reporting Value (MERV) rating refers to the overall efficiency of the filter. The higher the rating the higher quality of filtration.
