Perfect for our 3000 sq ft home. We use upstairs and downstairs. Recommended by our HVAC Service Professionals.

These are the only air filters I use in my house. I have allergies and cats and these filters do the job!

Quality product that I have used before and will continue to buy, product does a real good job filtering out household contaminants.

Since using these filters, my allergies have been much better. I like getting 4 at a time instead of one or two because I have several registers.

I purchased some of these at a different site and failed to note they were 5 inches wide!! I got four of them!! I purchased these to replace those.

I absolutely love these filters. They keep my furniture clean!! If the furniture is clean it is the reason we are not sickly!!! The air is clean !!

I got the filters without any issue. I've installed one and will know in a few months how well they work.

Good air filters at a good price. We have been using these for a few years, and they seem to help with allergies, etc.

I change my furnace filters every time the season changes. This makes it handy to order a year's worth every spring.

Filters are priced right. They do the job needed without paying high prices. A four pack will last us a while. Great product for the right price.
