Find your Air Filter Size


Depth
Most common house filters are 1" in the depth or thickness. If you measure your filter to find the real thickness you will find that it isn't the same dimension as it states on the filter. This difference in the real dimension to the printed dimension are industry standards and can be confusing. The printed size on a filter is called nominal size and is not the real dimension of the filter. So a 1" thick filter is normally .75" thick. To make it easier to talk about sizes we use the nominal dimensions to refer to filter instead of the actual or real size. Because you are creating a filter by selecting the real dimensions, it is important to know the real dimensions of your filter instead of the nominal or printed dimensions that show on your filter. We will show you the nominal dimension for the Depth or thickness because there are only 1",2", or 4" sizes. Now you would select 1" for your filter if you are replacing a .75" filter, if your filter is 1.75" that would be a 2" filter and a 4" is 3.5"
/
Size
Nominal Size: The printed value of a filter dimension. (15"x20"x1")
Actual size: Actual or real sizes of filters are typically .5" less than the printed dimension or nominal value listed on the filter. A filter of 20"x24" would be 19.5"x23.5"
