Product review (5 stars): It says NSF Cert and tasted fine.
Was reading thru the reviews and was 50/50 on giving it a chance. We had a really bad experience with some aftermarket filters we had bought at Home Depot so was a little nervous. Then I figured for Ten Bucks really not much of a loss when I am paying 3 times that amount for an OEM LG filter. This filter came fully sealed in plastic wrap and had NSF certified all over it which some people said they couldn't find. I replaced the filter today and ran a couple gallons thru it as instructed. Yes on the first quart there was some black charcoal but that is to be expected. After completing the flushing we were good to go. I tasted the water and I had no issues with it (and I really am not a plain water drinker) I will run it as I would the LG filter for 6 months and report back if any changes for the worse. I am satisfied with this purchase at this time. and would buy more. We are a family of two and own a LG with dual door Fridge on top and a pull out freezer drawer on the bottom.
