Product review (5 stars): Only filter I could find that is NSF Certified for both 42 AND 53 Standards
While there are many competing filters out there that meet NSF standard 42, the genuine GE is the only filter I could find that is NSF Certified for both 42 AND 53 Standards. The NSF 53 standard covers a whole different class of nasty contaminates that you really don't want in your water. They are also more difficult to filter out and require more advanced filtration which is probably why others can't meet that certification, and the ones that do, like this one, cost more. Search the web for understanding NSF standards and compare the two standards to see why you want your filter to have both. If you want your water to not only taste good, but be safe as well, this is the best I can find so far.
