The filter is undersized and does not fit standard 20x25x4 filter boxes.

This is my second order of 12 filters. I liked the white better for seeing the dirt, but I'm sure these will be just as good at filtering

Filter is excellent quality EXCEPT

Filter is excellent quality EXCEPT though advertised as 4 inches wide, it states in small print on the filter that it is something less than that? Why? Makes for a sloppy fit in my furnace and lets air leak around it. Otherwise a good filter that reduces the visible dust on furniture in the house.

Pleased with new size filter for recently installed heat pump

I have been using Filterbuy 20 x 20 filters in both my air handlers for the past few years. This year, following replacement of the older unit that served our home from 1985 to 2024, I discovered that the replacement Trane unit would only take a 17. 25 x 19 filter. I ordered the new size and now have a clean new filter in my new and older units.

The filters are excellent quality, especially for the price. The frame construction is sturdy and the media is top quality.

Hopeful Waiting

Your filters have a different appearance from others I have been using, and I believe yours are supposed to be replaced after 90 days versus the 180 from other filters. But I am hopeful yours will be at least as effective. I love that your products are made in the US. Your filters also arrived very quickly.
