Finding the right air filter size for your oven can be a daunting task, especially if you don't have an existing filter or if the existing filter doesn't fit properly. Fortunately, there are a few simple steps you can take to make sure you get the right size air filter for your oven. The first step is to measure the length and width (L x W) of the filter. If the filter is not square, the smallest measurement goes first.
It's important to note that the size printed on the filter frame is usually the nominal size, which may differ from its actual size. The next step is to check the size of your existing air filter. If you have an air filter in your oven, you can easily determine its size by looking at the numbers printed along the edge of the filter frame. This will give you an accurate measurement of the actual size of the air filter.
If your oven doesn't have an existing air filter, or if it doesn't fit properly, you'll need to measure the duct opening. Look inside the section of the oven where the air filter should go, there should be a 1″ filter track or opening where the air filter slides. Once you know the size of your oven's air filter, you can easily buy a new one with the same dimensions. Keep in mind that most disposable air filters are discounted (this is an industry standard) between ¼ and ½.
Starting from actual sizes, round measurements to the nearest whole numbers when ordering new air filters. This rounded measurement is called the nominal size and is used to match the correct filter to the air cleaner slot of the accessory. Timely replacement of your oven filter is much easier when you know what size air filter you need. With these simple steps, you can easily find out what size air filter you need for your oven and make sure it fits properly.
