Great air filters

These filters are great and make using the higher MERV rated air filters more affordable if you prefer that higher level of filtering

I just bought my 2nd batch of filters. I never miss changing the filter monthly. I wasn't sure how they would work out but I was pleasantly surprised. They are great! The price is fantastic. They do a good job. Im very glad I found Filterbuy.

I have been using Merv 13 filters from FilterBuy for several years now. They offer a wide range of sizes, they ship orders very quickly, and the filters are of great quality. I intend to continue using FilterBuy for all of my filter needs.

Not a fan of the

Not a fan of the blue colored material, these air filters are fashioned from. Other companies use white and this allows me to monitor when to change filters. My home is frequently surrounded by wildfires.
