If you are searching for a 12x20x1 furnace or air filter, we have several quality filters available in your size. You might wonder what the actual purpose of your air filter is. Originally, air filters were created for the sole purpose of basic system protection. This entails providing a barrier of protection for your HVAC components and ductwork from collecting dust. Keeping the internal parts of your system clean will preserve its life and ability to function efficiently. With a MERV 8 rating, you can be assured that you will accomplish the goal of keeping your fan, coil, and ducts clean and free from unwanted debris. You’ll also collect an abundance of microscopic particulate matter that is floating in your air. This is a great choice for those desiring plenty of dust control while capturing common everyday allergens. If you want added protection from odors, we also offer this same filter in an Odor Control option.
Many people are not aware that there are actually two sizes that you should be aware of when purchaing air filters. Our Filter Measurement Guide may answer some of your questions if you are unsure about the size you need. This will explain nominal (approximate) size vs. exact size. The exact size of our 12x20x1 filters is 11-1/2″ x 19-1/2″ x 3/4″. If you require a filter with slightly different actual dimensions, you may need a custom size.
