Product review (5 stars): Don't wait as long as I did to buy one
I am embarrassed to say I purchased this filter in May 2010 and it is still in use. Why? I forgot about it until today; I took out the filter and saw the date I wrote on it when I installed it.  I tested filling a large glass and it took 25 seconds. The house has a whole-water filter, plus a water softening system. The whole-house filter gets changed annually. So I guess all that has allowed the filter to work with no loss of flow and no odor or bad taste in the water from the refrigerator.  I just ordered another filter today. I have to say the filter is great considering what I have put it through and the service it still give me.  Eight years in use in three more months' time.  Wow!
