These have made a big difference in the amount of dust we get on our furniture. Plus the price for 4 is what you would pay for only 2 at most other stores.

These filters are a huge improvement over the standard filters we have been using. The air is noticeably cleaner and no particles or cat dander whatsoever.

I believe they work. Have the 1st of the pack we purchased in my handler now. I can't speak for the way they are supposed to remove odors, mold, dander, etc..as they say they do, but I need to replace my filters once every month as required by my property management company so I got these. With the price we paid its about $10 a month. I am good with that!

These 4pks are a great value!

great filters at good price

Good price as I use these filters often

The only brand filters we use.

Great filters for a great price, best deal you can get in furnace filters!

These are good filters, at a good price.

Really like these filters
