These filters are hard to find in stores. Filters Fast is easy to use and ships quickly. Also, I like that I receive a discount email when it's time to replace my filters. Recommend product and company.

The filters are fine. Your communication with your customers needs improvement. A simple email stating you were out of stock & when you plan to restock would have helped a lot.

Excellent Filter for my unit

Bob2025-06-16

Although the quoted nominal size 25 x 20 x 5 was the same as the Purolator filters I had been using, the actual size of your filters was different. One dimension was 1/8" smaller and another dimension was 1/8" larger. They did not fit well and I had to crush them a little to make them fit,

I appreciate Filters Fast for supplying the correct filters with the MRIV rating of 11. Sometimes they come before I need them, but I have spoken to them.
