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

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.

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!

Good price as I use these filters often

Great filters at a good price.

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

Really like these filters

great filters at good price

I love these air filters and the fact that Sam's Club always has them in 14x20 size is a bonus.

Very easy to install, great to trap and filter dust and keepbdust down.
