Just Right

We modified our filter opening from 1 to 4. We could only open it to 3. 7, and this filter fit perfectly, plus we did not want to go high than Merv 8, to put less strain on our fan, and again the filter was perfect, and was at our door 24 hours after ordering.

They advertised as a Merv 8 , 4 wide, but they are not 4inches wide. They dont fit my furnace compartment as they should.

Filters had trouble fitting into opening. Also, outside cardboard seems to be of inferior quality to previous Filterbuy filters. Not impressed.

I haven't had any problems with the filter I just put a new one in here in July so I'll have to eventually let you know down the road but far as I know that you know I'll tell you when I go here to three four months with it
