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.

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 like the package so I have some on hand.

Great price for 3 filters

4 pack of Filtrete allergen a/c filters work wel

I love these filters! I buy them every year when l start sneezing time to change the filter
