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.

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.

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

Great price! Allows me to keep a year's worth on hand.

Convenient and easy to use.

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

Great price on vital household items!

I like the package so I have some on hand.

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