Product review (5 stars): Great price. Fast delivery.
Honestly, who really knows whether your refrigerator air filter is working the way it's supposed to? I personally don't. And I don't think you do either. But we all feel better knowing that we have a fresh filter installed to do whatever it's supposed to be doing in there.

With that said, this rating is based strictly upon the fact that the price beats Sears, and that Amazon delivered it right on time. Can't complain!
