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!

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.

Pricy but one of the best filters I’ve ever used.

great prize and good product will buy again.

I was so glad to see that Sam's had the size filter I need.

I like the package so I have some on hand.

Long time user of this product, theu work as expected.

Been using for years, good product

I always use these filters on my home and change them quarterly.

Well made filters for a decent price.
