Product review (5 stars): Excellent product - does what it's supposed to do.
We've been using these filters in our Samsung unit since purchasing it.  Because we have hard water, we can't get by without one.

BUT: I do not get why Samsung charges $40+ for a filter - it's a bit much.

IMPORTANT: you MUST run at least a gallon of water through it when you first install, otherwise you'll have grey ice cubes!
(I think it's probably excess charcoal from the filter but don't know for sure)
