Product review (5 stars): Works Great!
I'm not a scientist who has done extensive research nor have I done any sort of PH test on the water, BUT, the water tastes just as good as it did with the expensive Samsung brand filter. The filter hasn't leaked at all. There's no weird black particles in the water. I can either spend $16 a year or $100. I'll let you guess which I prefer.
