With the recent particle and smoke from wildfires, these filters kept our indoor air clean.

I have used Filterbuy for several years and they continue to be a great buy for the truly good performance. I prefer the MERV 13 for filtering out my pets and keeping microbes in check.

Great filters at a reasonable price!

I'm very pleased with the replacement filters for my HVAC system. I ordered the same ones last time and they do not disappoint. Also, they arrive MUCH sooner than expected. I saved more by ordering in bulk.

20x20x4 filter is only 3. 5 inches

These filters are a full half inch less deep than advertised, and almost an inch less than the 3M filters I have been using. Pretty disappointing.

Great product, great service

Love the option to set up recurring orders (and modify as needed). Would prefer a lighter color (easier to see when they are getting grungy) but overall great product.
