Filter is exact replacement for the Lennox OEM product. Fits properly in the filter unit. 2 pack is individually wrapped, so the 2nd filter will be 'fresh' when I need it this spring.

Did you know that the nominal size of your air filter is probably not the same as the actual size? Just like measurements on lumber, the actual size of an air filter is usually slightly smaller than the nominal size.
