Good filters faor price

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.

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.

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!

When my new furnace was installed, the installer suggested using the cheapest fillers and replacing them monthly so I did. Over time I noticed when the furnace came on it started feeling stuffy and almost harder to breath even with a fresh filter. My furnace is located next to the washer and dryer and I have two dogs. Decided to switch to the much higher quality filters and what a difference! Now when the furnace comes on besides the warmer air I notice no difference in my breathing. Definitely worth it. I change my every 2 months during winter months just for peace of mind but I do check it every couple weeks to see if it’s dirty.
