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.

We have used the Filtrete air cleaners in our a/c and heater for many years and have been very happy with them. They will easily make it two months without replacing, but we choose to replace them every month.

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!

great filters at good price

The only brand filters we use.

Good price as I use these filters often

Have seen much improvement in house dust & air feels cleaner

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

Really like these filters
