What's the most common size air filter?

Currently, the most common size oven filters are 10x20. But if your system needs custom-sized air filters, please note that we offer custom sizes ranging from 8 x 24 x 1 to 25 x 30 x 1.Let's look at the most common oven filter sizes and where to buy oven filters. Honeywell, Hunter and Whirlpool have several models of room air filters available, so it's important to check compatibility before purchasing a replacement. Here's a fun fact: 70% of what Filterbuy sells is out of the 10 most common air filter sizes.

Whole house AC filters with a size of approximately 3 to 6 inches wide can have a lifespan of 6 to 12 months, depending on environmental conditions. Please note that the number of models of many filters is very similar, please check the actual size (actual measured dimensions of the filter) to make sure you have the correct filter. Worse, incorrectly sized air filters can put excessive strain on your HVAC system, damage it and increase your energy bills. Knowing more about the sizes of air conditioning and oven filters can ensure you find the perfect size for your home.

Lennox has a MERV 16 filter option as offered in the Lennox Pureair system, which is among the highest efficiency residential filters available and is also recommended by Lennox as an upgrade to specific Carrier, Trion Air Bear and Honeywell systems. When searching by brand like Lennox or Carrier to find a Carrier oven filter size by model number, you can use a Carrier filter size search from the table above or with the Lennox size search and this is how you would do it. Round up to the nearest inch to create the nominal filter size, which is the measurement you will use when purchasing a filter. Placing the filter backwards may cause the filter to collapse and cause airflow to circulate around the filter.

Airflow in the wrong direction of a filter can create greater resistance and cause a strain on the system. To check the size, turn off the system, remove the filter from the compartment, and look at the dimensions. If that doesn't work, you may be able to find the appropriate air filter dimensions in the HVAC manual. It is important to note that there is no need for an airtight seal between the frame and the air filter.
