We've used these filters for years and love them. No issues. This is our first time buying directly from the seller. It was a wonderful experience. I'll buy direct from them again!

This is difficult size to find. FilterBuy has this size in different filtration filtration configurations which is very helpful. It fits perfectly in my furnace and does a good job.

All the filters are just what I needed. They help control the smell from laser engraving and curing.

Fast shipping; decent product.

Faster shipping than anywhere else, great prices for bulk, and good quality filters. Thats what I was looking for. The website, like most storefronts these days. makes it a little too easy to accidentally select a subscription, so watch for that when checking out. If you do want a subscription, thats the best price. Filter quality is fine, with no issues.

Perfect fit

I am very pleased at the results of these filters. I'm on my 2nd year using these filters. It takes 3 filters for my unit, and they fit perfectly. My Plenum Air area is super clean changing filters every 3 months. I cleaned my evaporator last month and it looked great before the cleaning. It's nice keeping my unit new.
