Have not opened these yet but it is a product I use almost exclusively and is always a good performer.

My son an HVAC technician said too high of a rating makes your furnace work harder. This was the only filter I could find that fit my furnace

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.

My daughter has allergies and these filters work great and really seem to help with the desert pollen

They work great and it’s cheaper to buy them in a set than individually because they are cheaper in a set

Just What I needed. I love these furnace filters. I have little or no dust & the house spell fresher

We change these every month. It was great to find the correct brand and size at Sam’s and the price is way better than where we normally buy them.

Great product last longer than other semilar filters and you can definitely breathe the difference. Price at Sam's is best deal we have found .

It's great to grab a bundle of these to have on hand, now I have no excuse for not changing the filter regularly

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.
