Choosing the Correct Filter Size
Nominal Size vs. Actual Size
The nominal size is a shorthand number rounded to the nearest whole or half inch, normally in a larger font (ex: 16 x 16 x 1). Whereas the actual size is an exact measurement, normally in a smaller font, that depicts the filter's precise dimensions (ex: 15.75 x 15.75 x .75). All filters have both.
Measuring Your Air Filters
If your current air filter does not have a dimension listed on the frame, use a tape measure to record the length x width x depth to find the actual size. Then round these measurements up to the nearest inch to find a corresponding nominal size, which will be easier to locate when searching online.

This Review Pertains To Sizing.
I bought a pack of these filters because they were less expensive than Filtrete, which I already had in my furnace. When the Filterbuy pack arrived, they looked good, and I went to replace my old filter with a new one. There is quite a big difference in the size of the actual filter to what is written on the box. The Filterbuy slipped into place so easily, it didn't fill the gap. We have a couple of end caps to fix this, but they didn't fit the filter, so my husband had to try and secure it in place to prevent it moving around. Got up this morning and my furnace is not working properly; temp was set to 66 degrees and it was 62 when I checked the thermostat. I've had to put my old filter back in place and will return the Filterbuy. I have ordered two Filtrete filters because I know they will fit. Please be sure that you check the small print on the Filterbuy filters to be sure they will fit securely in your furnace. I'm not saying the Filterbuy brand are bad, they are just sized differently. Hope this helps.
