HVAC units have a standard size filter that is mass-produced and easy to find. Each unit has a specific size filter that allows it to work correctly and efficiently. There are also cuts in filters throughout the house, but not in the same way as in filters 1 and 2.In reality, they are rounded to whole numbers in an arbitrary way. 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.
Usually, the filter size is printed along the edge of the filter frame. Note that the size that appears in bold on the filter frame is the nominal size of the filter, which is likely to differ from its actual size. If the actual dimensions do not appear in small print on the filter frame, it is recommended to measure the filter to check it. Step 1: Measure length and width (L x W).

If your current air conditioner filter does not have any size, you can measure the length, width and depth of the filter and filter to find the actual size of your filter with the corresponding size of the oven filter in the oven filter size chart (nominal size).
Different manufacturers cut whole-house filters into different sizes and then round them to standard measurements, which means that two 20 x 25 x 5 whole-house filters made by two different manufacturers are probably not the same size. Since air filters are usually sold for their nominal dimensions, it is essential to learn how to measure them correctly. Whole house filters usually go to an air controller, which is usually found next to the HVAC system itself.
