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.

Great price when compared to Lowes contractor 4 pack, I have been using the 1600 filtrates for years. I have 2 Fur babies so i change the filter every 2 months. AC service guy says the inside of my ac is very clean so they are doing a great job

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.
