Product review (5 stars): good value - saved money from the GE one but works the same
this filter saved me some money compared the the GE one that we had been using. It seems to work just as well but when we first installed it, it seemed to make a bit more noise. It is no more noisy now than our other one so I am not sure why it was noisy at first.

I have no clue how well this works to remove impurities I think it is more for keeping the mineral deposits from accumulating in the tubing. I would not expect pure water from this but then again I did not expect it from the GE one either

We will buy this unit again if the price remains low
