Some how I received the wrong size, even though the receipt states the correct size I wanted.Now my membership is expired and wondering if I can take it back.

Great filters at an amazing price. Got these when there was instant savings applicable, but they are a great price even without the additional off. Did my research and found them to be highly rated. I had purchased just one elsewhere because I was desperately in need of a new furnace filter. When I saw these at the price Sam's was offering it was a no brainer to grab the 4 pack for future needs.

The 14x25 filter is probably fine if you have a smaller system (2 ton AC or less). But at 1200 cfm (typical for 3 ton AC), the airflow restriction is 0.47 wc which is quite high. It caused my AC to throw an error, even with a new filter right out of the package... not after it ran a while and caught a bunch of dust and stuff. Other Filtrete options have better airflow performance. Just wish Sam's sold em!

We purchased these filters last year and again this year as well. The filters def last 3 mo each so although it seems like a lot of money for a package of filters, you have to remember they last a whole year. When you price these filters individually you realize you save a lot buying a multi pack.

We have never used the more expensive ac filters before but we can really tell the difference with these. They catch so much more dust & particles out of the air, I don't have to dust the house nearly as often. So it is definitely making the air cleaner to breathe.
