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.

Good value but filter size is just a hair too big for the vent. Had the same problem with our previous house and this brand. Requires bending the filter a little to make it fit. Wish a big company like 3M would cut these to proper size.

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!

Good for keeping fist out of the home

The only brand filters we use.

They work well and last 3 months generally

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

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

I like this better than the cheaper ones they work a lot better
