How to Measure Air Filter Size Accurately

Are you looking for a way to measure the size of your air filter accurately? If so, you have come to the right place. In this article, we will discuss the steps you need to take to measure the size of your air filter correctly. The first step is to measure the length and width (L x W) of your filter. If the filter is not square, the smallest measurement should go first.

Then, measure the thickness (depth) of your filter from front to back. Once you have all three measurements (L x W x D), you can gather them together. Most air filters have their size printed on the side of the frame. The length, width, and depth of the filter are measured in inches.

For example, it will say something like “16x25x1”, where 16 is the length, 25 is the width, and 1 is the depth. The dimensions indicated on the side of the air cleaner frames and printed larger on the air cleaner package are usually the nominal size dimensions. These measurements indicate the length, height, and depth (thickness) of the air cleaner, rounded to the nearest inch. An example of nominal dimensions would be 16 x 24 x 1.If the filter is too large, it will not fit into the filter slot and you will not be able to replace the cover.

We recommend that you start your search for the replacement air filter by reducing the depth of the air filter. Therefore, no matter what situation you are in, you can calculate the size of the filter you need to buy by rounding up to the nearest inch. Determining the proper size of an air filter can be confusing since filter packs generally show two sets of dimensions. We recommend removing the existing filter and measuring it to confirm its actual dimensions.

Always open up the air cleaner grille to take measurements; do not assume that its inside measurement is equal to its outside measurement. On air cleaner packaging, this number usually appears below or next to its nominal size and is usually in a smaller font size. AC filters come in many different sizes so it can be overwhelming if you don't know what size filter you need. The easiest way to determine your oven filter's size is to check its old air filter's size. In some cases, length and width are interchangeable but you'll always need to make sure that you measure those three specific dimensions of an air filter or oven filter accurately.

These are exact dimensions when measuring length, width, and depth (thickness). If it is easy to access, measure the slot in your air cleaner housing or refer to your oven's operating manual for more information. If you have purchased a wrong-sized filter, don't worry! You can always build a custom air conditioner or oven filter that allows you to choose specific dimensions if standard sizes don't work for you. In conclusion, measuring an air filter's size accurately is essential for ensuring that it fits properly into your oven or air conditioner unit. To do this correctly, make sure that you measure its length, width, and depth (thickness). Additionally, always refer to your oven's operating manual or measure its slot in your air cleaner housing if it is easy to access.
