The filter was not completely 4 in, so I have a gap in my filter still. Not sure why you don't make them a full four inches. . .

It is hard to find

It is hard to find the exact size filter in my area. Until Filterbuy, I always had to buy a Filter and cut it to fit. Thank You for having my "exact" size in stock, with many quantity options!
