These are great. We switched out after six months and it was disgusting to see the collection of dust particles. Great to know it wasn't in the air we breathe.

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
