Smaller Than the Size States

These filters aren't the measurement indicated. Received ours and put one in the furnace and it flip flopped from side to side and top to bottom. Our furnace company said that this will cause the furnace to work harder putting undo strain on it. We returned the filters.

GREAT price and work just as good as more expensive filters. I actually think these are better. My house isn't as dusty as it used to be.

Merv 13 Pleated air Filter
on September 20, 2025
Posted by: Anonymous
Have been using this product for 2 plus years. Upon upgrading to the Merv 13 filtration, I noticed some dustballs collecting on the filters after first couple of filter changes. Now, no dustballs. These filters use "nominal" sizing. I had to add shims to filter box in order to prevent air bypass. I use the 4" deep filters and change every 4 months. I'm very satisfied with performance of these filters and will continue to use.

This filter saves us the hassle of too frequent cleaning the house, being in a construction zone.

Excellent company to deal with

[This review was collected as part of a promotion.] I've dealt with Filterbuy 3 times and they have always had great service and products. The filters are as good or better than name brands and you can find any size you need. They are also made in USA with an excellent price and shipped free. I definitely recommend this company.

Hoping these filters help to cut down on a fine white dust that is everywhere in the house! The company I deal with only changes filters once a year. They have also changed filter style. Wish me luck. .
