Great Product

Reasonable price

Steve Courtney
Best Choice for Filters

Pricing is the best we found, and the added bonus is the customer service. Filter came within a few days. We had to deal direct with customer service because we had ordered the wrong size and did not realize it until the package came. Return process went seamless as well. We will order again, and keep their website handy to share with others.

Wonderful customer service

I initially ordered the wrong size (oops) and called. The gentleman canceled my order and I reordered the correct size online. Came right away. Just what I needed. We will order again when needed in the future.

Roger Cunningham
Good pricing & excellent customer service

I made a mistake with the measurements for the accordion style heat pump filters I had ordered, totally my mistake, but Atomic Filters' took care of me. I was able to return them for a quick refund & I got the correct size within a few days. I'll definitely keep ordering my filters from Atomic Filters; no more over-priced filters from Home Depot for me!
