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.

Been using for years, good product

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

Great price on vital household items!

I always use these filters on my home and change them quarterly.

Best price and now we have one handy when needed.

Convenient and easy to use.

Had to be forced into opening. Possibly a second.

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