Works great but when a 20X20X4 filter is not 20X20X4 then I had to shim the filter to fit properly in my furnace.Other than that it is a great filter.

The filters fit perfectly, delivering was really quick. My furnace uses 3 different size filters got all the ones I needed with higher rated Merv ratings. Everything was by the book and very professional.

I have purchased this exact filter before. This time it doesnt fit. I had to trim it to fit it in. I did not have time to return it because I am heading to florida but I will not be purchasing another one. I purchased 2 thinking I would be set for the winter. I dont understand why you would change the design when people think they are ordering what they have purchased before
