Your filter fits better than what I was using, is priced right, and I can stop looking for this odd size.

I have been using Filterbuy for a few years. Their wide variety of sizes and filtration is excellent. I will continue to buy from them.

My filters are an odd size, but Filterbuy had them. The quality is great. I would definitely buy from them again.

I love that you give the precise measurements.The 20" X 20" I used to buy fit too tightly and I would have to crush them to slide in. 19.5" X 19.5" makes it so much easier to slide in and out.

They are easy to deal with and allow custom sizes that fit filter vents in older homes with different sized openings.Also, reasonable priced.
