Too big. Had to be forced in. I take a 20x30x1 filter and bought a 20x30x1 but this seems to be .3 inches wider then it supposed to be. Would be a good buy it fit. Maybe a factory defect?

I had no problems with the older version/model of this filters. The filter mesh was different. This new version restricts airflow and will cause ac problems.

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!

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.

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.

This filter may work great on new HVAC system but I don’t recommend using this filter on an old HVAC system. After installing this filter, I noticed that he blower fan kept running continuously. I had 2 different technicians replacing several parts (relays/switches) but the problem with the fan was not fixed. I replaced this filter with a standard filter and the unit is running OK and the blower fan start/stop as set.

Bought these as part of an email promotion but didn’t receive the credit. A trip to the service desk and four calls to members services resulted in a members rep repeatedly putting me on hold while I was talking and giving no response. Decided it wasn’t worth my time or frustration. Returned them.

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 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.
