Product review (5 stars): My house has new plumbing and the water out of the tap is actually clean and pretty good, except that municipality gets a little
I went through few authentic Samsung water filters in the last year.  My house has new plumbing and the water out of the tap is actually clean and pretty good, except that municipality gets a little happy with the chlorine from time to time.  The filters would act like they were clogged, and the water would come out very slow.

After the last one from Samsung -- which only lasted a couple weeks, I ran the fridge without a filter for a couple months and was pretty happy without it, then the water got a heavy chlorine treatment and wasn't so tasty.  I bought these to see if I'd get better performance, and have been really happy.  This is the first time I've seen the "change your filter" reminder come up on my fridge in year that I've owned it, and the filter continues to perform well.  My guess is that the other filters were easily damaged internally by changes in water pressure, and we've been doing work that requires shutting off the main water supply and stuff both with the Samsung and this filter installed.
