Product review (3 stars): Good for aesthetics, not for eliminating health risks.
Be clear that this filter only eliminates chlorine and dirt (basically) from your water and NOT lead, bacteria or other chemicals. I read up on ANSI standards after I got these. In fairness, the filter is listed as ANSI 42 (filters for taste) vs. 53 (health contaminants), but I don't appreciate that the listing implies that it "protects health" and "enhances immunity" (unless they mean that, by exposure to bacteria, your immunity is enhanced).

In my case, my refrigerator is on the back end of a reverse osmosis system, so I'm comfortable using them, but unless you have some other filter in place, find a refrigerator filter that is ANSI 53 certified.
