Air conditioners and ovens both require filters to operate correctly and efficiently. Most air conditioning and HVAC units use standard-size filters, but some require the purchase and installation of a custom-sized air filter. The filters are labeled with three-part dimensions, which include the length, width, and depth or thickness. Oven filters are also available in hundreds of varying sizes, as the air filters and the oven are the same.
Filter King offers hundreds of different filter sizes that can be used in various home systems, including your oven. To ensure that the next filter you purchase is the correct size for your system, you should measure the inside dimensions of the air cleaner inlet. Note that the sizes of the air conditioner and oven filters must be smaller than the dimensions of the filter compartment. Round to the nearest inch to create the nominal filter size, which is the measurement you will use when purchasing a filter.
This rounded measurement is called the nominal size and is used to match the correct filter to the air cleaner slot of the accessory. Installing several 1-in-a-slot air filters can cause costly damage to your air conditioning unit, as residential ovens are not equipped to handle this level of airflow restriction. However, you can choose not to use factory-installed filter grids and have an HVAC professional install an external filter grid to get a coarser filter. The easiest way to identify the size of the AC filter is to remove the existing filter from its slot and examine the filter frame.
There are several great options to buy air filters online and have them delivered conveniently to your door.
