When it comes to buying an air filter for your air conditioner, it's essential to make sure you get the right size. The easiest way to identify the size of the air conditioner filter is to remove the existing filter from its slot and examine the filter frame. Usually, the filter size is printed along the edge of the filter frame. Please note that the size shown in bold in the filter frame is the nominal size of the filter, which is likely to differ from your actual size.
If the actual dimensions do not appear in small print on the filter frame, we recommend measuring the filter to check it. Step 1: Measure the length and width (L x W).If you live in an older house, with a non-standard size air return frame, you may want to use adhesive foam tape to protect the weather to slightly increase the dimensions of your favorite filter, or order a custom-sized air filter. When in doubt, you can always measure the air filter yourself with a ruler or any other measuring device. Most air filters are located on the right or at the bottom of the unit and can be easily removed from the slot. Most white pleated air filters are inherently the same within each efficiency level, and vary slightly, if any, from brand to brand.

Even if you are trying to place several air filters in a small space, it is not advisable to stack them on top of each other.

However, if you can't determine how often you should change the filter, there are several warning signs you should pay attention to; for example, if the air filter is dusty or no longer working properly, it's time to change it. To make sure it fits you properly, take out your current air filter and check the size printed on the frame. You want the air filter to cover the duct opening. Measure the height and width of the duct opening and allow it to overlap a little if you have space. This will be the exact size you'll need to order for your new air filter.
