What Are the Different Sizes of Air Filters for Homes?

When it comes to air filters, there are hundreds of different sizes available. From 6, 88x15, 88x2 to 8x30x2 and 9.75x23, 75x2 to 10x10x2, the size of the filter you need depends on the size of your air intake vent. To determine the size of your air filter, you'll need to measure the length and width (L x W) of the filter. If the filter is not square, the smallest measurement goes first.

Air filters can be changed from behind the intake grilles (often called air filters or AC filters) or in the oven box of the central air unit (often referred to as “oven filters”). Most air filters have a MERV rating between 1 and 20, with MERV 1 filters only capable of removing larger debris and MERV 20 capable of filtering microscopic particles such as viruses and bacteria from the air. The length, width and depth of a filter are printed in small numbers along the filter frame on the cardboard edge of a Filter King brand filter. However, while filters offer many advantages for your system, your home, and your health, they need to be changed regularly.

If you don't have the old filter handy, you'll need to measure the actual size of your air filter in the intake vent. On the one hand, this can greatly affect the amount of air pollutants that are filtered, leading to poor indoor air quality. There are hundreds of varying sizes of oven filters because the air filters and the oven are the same. Air filters, oven filters and AC filters are similar products and the terms are used interchangeably. Whether that means cost, efficiency, effectiveness, or size options, Filterbuy has the widest selection of standard air filter sizes, each with MERV rating and ODOR fighting options. You can choose how much filter you need and get a replacement air filter that's perfect for your home.
