Product review (1 stars): Know what you're buying...
Originally I was satisfied with this water filter, but I was just looking for a less expensive option that fit our model. I figured that with all of the positive reviews, and the claim of NSF certification, that this would be fine for what I needed. I was in for a huge surprise shortly after installing and not giving a second thought to this filter - that fit perfectly. I was reading an article about local water contaminants and their long term effects and decided that I should probably spring for an inexpensive water testing kit, just to make sure I'm not exposing my family to unnecessary toxins. I purchased one of the little water sticks and ran a test on our tap water - it registered just in the acceptable range. Just. As in 274 ppm. Who knows what those 274 parts per molecule are, but I was not pleased. At least we only drink the water from the filter... At this point I was leary about the water testing stick, so I did some research and purchased another. I used both to test the tap and filtered water and the results were infuriating. Our tap water still registered high with the two meters reading 276 and 265, both far too high in my opinion. The filtered water registered 245 and 237. It barely made a difference! Now, I feel like I spent far too much on a product that does little more than fit in the right spot. I was so irritated, I could not understand how they could possibly be NSF certified, so I decided to research that as well. NSF certifications for residential, point of use water filters are designated by rating, the lowest being for aesthetics - smell and clarity, which if certified, would have an NSF/ANSI 42. This claims to be "NSF certified" with no designation. At this point, I didn't expect to find this filter, but in the interest of due diligence, I searched NSF.org for the manufacturer Purity Pro, the part number PF02, the OEM replacement part, all with zero results. Nothing. Needless to say, I won't be making this mistake again.
