Product review (1 stars): These are for taste only and DON'T remove toxins...
It is very misleading but these are ONLY NSF/ANSI 42 certified. These DO NOT meet the NSF/ANSI 53 standard which is to remove heavy metals and other toxins. If you are buying these, understand they are simply to improve taste and nothing more. If you want a water filter to remove potentially harmful stuff, stick with the factory filters as they are rated for NSF/ANSI 42 and 53.
