The filter fits perfect in the slot and looks good. I will see how it does after 3 months go by. I am glad I bought these filters with this company FilterBuy.

Im sure this filter is good quality, however maybe it is TOO good! It doesnt seem to let enough air through, and makes a whistling noise. Next time Ill get a lesser grade, hoping it will pass air better.

These are the best filters.

These are the best filters. Keeps household dust way down,and thats with me having 2 litter boxes and 4 cats. What an air quality difference it has made. In Florida,we have pollen all year round,so these filters are just perfect. Will never buy from anybody else. And the fit is perfect every time.

Needs improvement

Pleats were distorted in spots, border is flimsy and filter fits loosely in the cold air return which allows air to pass unfiltered.

Using filterbuy for my filter replacements makes it easy. Especially when you can go to your orders and hit reorder. Great quality filters too!! Especially with all of the allergies of everyone in our house.
