Lennox Filters

Lennox Air Filters come in many sizes. As with all furnace, HVAC and AC filters they are interchangeable with any brand as long as you replace with the same filter size. While we don't carry the Lennox Air Filter brand, we have a large selection of replacement air filters in the same standard sizes that perform just as well if not better. Plus you have several efficiency rating options and can save money with many of the filter options we carry. We only work with leading manufacturers in the indoor air filtration industry for both commercial and residential systems.

Exact Fit Furnace and AC Filters

The most important thing when replacing your filter is the size. Brands are interchangeable.

Instead of bringing in cheap restrictive filters from overseas, high priced filters because of marketing or  brands using lesser quality materials and processes like some of our competitors, our air filters are made by leaders in indoor air filtration.

Choose from MERV 8 filters designed to protect your system, capture dust and allow maximum airflow, or go as high as a MERV 13 filter to pull viruses and bacteria out of the air.
