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 20 x 1). Whereas the actual size is an exact measurement, normally in a smaller font, that depicts the filter's precise dimensions (ex: 15.50 x 19.50 x 0.75). All filters have both.
Measuring Your Air Filter
If your current air filter does not have a dimension listed on the frame, use a tape measure to record the width x length 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.

Great quality and value. It fit perfectly and really helps cut down on dust in the home. Arrived quickly and it doesn’t need to be replaced as often as other filters.

These are great filters that perform perfectly, except for occasionally being slightly damaged when I receive them. The cardboard frame is sometimes deformed or damaged which makes it somewhat difficult to install. Not sure if this is a manufacturing issue or a handling problem.

Great quality, great fit especially since it's an odd size, or one that's not carried in store.

The filters arrived damaged.I was asked to return at my cost and I didn’t think that was right.Filterbuy asked for photos on two separate occasions.Then told me to destroy them.I said that I didn’t want replacements but the said that they had sent them out.After messages back and forth, they said that I would be refunded.Still waiting to see that happen.
