Review: Stick With The Overpriced OEM - I purchased this to replace a single filtration unit for a pre-April 2018 bottleless Avalon water filter unit. It was indicated that it would fit my model but alas, it did not. A waste of time. The OEM filter costs 4x as much, but at least I know it will work. I tried to save some money an ended up just wasting time and effort. Sometimes you have to bow to the filter gods and pay the tariff for hard to find items. ~ Kort ## Features - Fits iSpring under sink ultra filtration system CU-A4.
