Cleaner air

The air quality in Phoenix valley is dusty and polluted. So far, after three weeks, inside air quality seems to be better. Time will tell.

Very effective filter for my air conditioner traps a lot of my pet hair and the flow of the cooling air is smooth.

I know they are not 3M brand, however, they seem to work just well . . . . . . . . the size is perfect and they fit well. . . . they are a quality item and I know that because there is a smoker in my home and they help greatly clearing the house of smoke and it's awful left behind odor!

Great filters. Best of all I don’t have to think about it. They automatically come in the mail and is a great reminder to replace the filters on a regular basis.

Excellent buy

The shipping was quick. The filter seems to be working well. With two old shedding pugs, the air in my house needs all the help it can get. My allergies seem to be better. If they really do last 3 months, then this was a fantastic buy. Only time will tell.
