Are you wondering what the most common air filter sizes are? If so, you've come to the right place. In this article, we'll provide a comprehensive guide to the different sizes of HVAC filters available, as well as how to identify the size of your existing filter and where to buy replacements. When it comes to air filters, the size is usually expressed in terms of length, width, and depth (L x W x D). The easiest way to identify the size of your AC filter is to remove it from its slot and examine the filter frame.
Usually, the filter size is printed along the edge of the filter frame. Note that the size that appears in bold on the filter frame is the nominal size of the filter, which is likely to differ from its actual size. If the actual dimensions do not appear in small print on the filter frame, we recommend measuring the filter to check. The most common air filter sizes are 20 x 20 x 1, 16 x 25 x 1, 20 x 25 x 1, 20 x 25 x 4, 16 x 20 x 1, 16 x 25 x 4, 20 x 30 x 1, and 12 x 12 x 1.It's best to have a little wiggle room in the slot of your HVAC unit, so you can easily slide the filter in and out without it bending or breaking. When it comes to buying air filters with convenience, you have several options. You can buy them online, through your HVAC service company, or in-store.
Newer system air filters not only focus on protecting equipment but also on improving your home's air quality. This is one of the major health problems listed by the EPA, CDC and American Lung Association. If you're looking for a specific brand of air filter such as Lennox or Carrier, you can use a Carrier filter size search or a Lennox size search in the table above. Standard oven filter sizes (also known as standard air conditioning and oven filter sizes) and hard-to-find sizes are included in the list with actual sizes and MERV options. Lennox offers a MERV 16 filter option in their Lennox Pureair system which is among the most efficient residential filters available. They also recommend it as an upgrade for specific Carrier, Trion Air Bear and Honeywell systems. For common brands of HVAC systems such as Goodman, Lennox, Trane, Rheem York, Coleman and Carrier, most standard air filter sizes will work.
Keep in mind that the model number of many filters is very similar so check the actual size (actual dimensions measured by the filter) to make sure you have the correct filter. Colorfil filters were originally created for NASA and help remove chemicals and odors at a molecular level that normal air filters can't remove. From filtering harmful contaminants to keeping your HVAC unit running efficiently, these products have several benefits. HVAC service companies often offer air filter replacement services in addition to system repair and unit installation services. The primary function of air filters is to protect your HVAC equipment from damage that can be caused by the accumulation of dust and dirt on the coils. The list of location HEPA filters for sale usually includes compatible models in the description or in the vignettes so be sure to check compatibility to make sure you buy the correct HEPA filter for your air purifier.
