Keeping Water Clean Review by Goose in CO
It was extremely nice to receive a reminder email from DiscountFilters to remind me that my filter was about to expire. Sure enough I received the filter and within a couple of days the filter light on the fridge lit up. Perfect timing! The filter works great and yields the perfect cup of coffee! (Posted on 8/2/12)

Does what it's supposed to... Review by McArtesyn
Once you buy the fridge with a water dispenser you need the filter. Kind of expensive considering the life of the filter. It does make a big difference in ice cube clarity however. (Posted on 1/6/10)
