Im a first time buyer. Replacement filters were slightly smaller than the original. I dont know how this affects their performance but will watch to see if they perform.Price is good.

They were very reasonable compared to what weve paid elsewhere and work just as well.

This matched the manufacturer's number/size but upon installation hubby says it is about 1/2" shy. I will cancel my reorder until I figure out what went wrong.

Filter Buy makes buying filters very easy. I was also very surprised with the speed with which the product was shipped.
