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!

I've been using either the Merv 13 or Merv 12 rated filters for several years and I find there doesn't seem to be much of a difference in lost air quality in our home. These filters, offered by Sam's Club at the sale price, are a significant savings for the package of 4. So much so, I made and second purchase for another four pack while they were still on sale.

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

Excellent air filters. Excellent price!

Quality filter and the ability to be reminded when to replace is an asset for sure !

great prize and good product will buy again.

I needed new filters and had been putting it off. Now I have extra.

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

I have not used the filters as of yet. But I trust Filtrete. I’m sure they’ll work just fine.

Good filters. Good price compared to Walmart or Home Depot.
