About the Lennox X6675

The Lennox X6675 Air Filter - MERV 16 - 20" x 25" x 5" is unique in that it offers a carbon-coated filter matrix. It’s dark gray color comes from the carbon and offers added ozone and odor reduction capabilities to the industry’s highest efficiency air filter.

The Lennox X6675 air filter is a genuine, OEM Lennox X6675 Healthy Climate Carbon Clean MERV 16 filter. The electrostatic media captures viruses, bacteria, dander, pollen, dust, and many odor-causing agents. These highly efficient filters maintain airflow while offering air pure enough for hospital rooms and reduce ozone. The carbon technologies make this the best filter (short of a HEPA) available, maintaining optimal health and comfort in your home.

Some of the features that make the Lennox X6675 unique include:

  • 50% First-pass reduction of ozone
  • Hospital inpatient / general surgery level filtration
  • Removes over 95% of (sub-micron) particles down to 0.3 microns
  • Removes over 90% of ultra-fine particles down to 0.1 microns including viruses and bacteria
  • Includes a carbon-coated fiber matrix to trap and capture odors

If you need an additional layer of protection in your home for allergies, asthma or other breathing conditions, this is the best Lennox filter you can choose.

The Lennox X6675 MERV 16 filter is a suitable replacement filter for the Lennox HCC20-28 air cleaner as well as many Honeywell, Carrier, and Trion Air Bear air cleaners that accept a 20" x 25" x 5" filter media. The Lennox 6675 air filter is designed to fit the following air cleaners:

What do the Numbers and Information Mean on Lennox Furnace Filters?

The Lennox Healthy Climate filters are designed to offer a high-efficiency option for home-owners. MERV stands for the Minimum Efficiency Rating Value and is a scale from about 1 to 20. The scale represents the level at which a replacement filter is removing small particles out of the air each time it passes through the filter. In general, a rating higher than 7 is designed to protect and improve air quality within a home. Ratings from around 11-13 are designed to be highly efficient and are ideal for those with severe allergies or breathing issues. The MERV-16, which is what the Lennox X6675 Air Filter is, offers the highest efficiency outside of a HEPA filter and is safe enough to use in hospitals, homes and more.

How Often Should I Replace My Lennox X6675 Filter?

Typically, 5” furnace filters should be changed every 12 months or when showing obvious signs of being dirty. However, with the Lennox X6675 filter, we recommend you replace it every 9 months to ensure it is running effectively and filtering the air as much as possible within your home. When an air filter is clogged or dirty it is not efficiently filtering out air particles, which could put individuals with allergies at higher risk. Not to mention, a clogged filter can cause lasting damage to your filter and actually decrease its overall lifespan. When air can’t pass through the furnace, it traps heat in your system and can lead to a variety of issues.
