Nordic Pure air filters have an actual size that is a fraction of an inch smaller than the nominal size. with the 4-Inch and 5-Inch air filters there is a wide variance between the nominal size and actual size.

This is why we ask you to measure your filter so you aren't surprised if the filter doesn't fit! Our MERV 14 four or five inch air filter should be changed at least every 6 months depending on your environment.
