Lennox Air Filters

Get fresh air for less

In order to run efficiently, a home’s Lennox air conditioning and heating unit needs a quality air filter.  A furnace with a poorly made or clogged air filter has to work twice as hard, which can ultimately shorten the life of your furnace.  At Discount Filter Store, we understand that while you want a quality air filter you don’t want to pay a fortune for them; that’s why we’ve made it easy for you to find all of the replacement Lennox filters you need, at the lowest price.  Our huge selection of Lennox replacement air filters are available in three different MERV Ratings, in over 10 different sizes, and with two primary filter medias.

Keep the air in your home or office clean and clear with a Tier1 replacement Lennox air filter.
