How We Chose the Best Generic Refrigerator Water Filter
To choose the best generic refrigerator water filter, we compared filters sold on Amazon in the U.S. on exact part-number fit, NSF/ANSI certifications listed by each brand (42 for taste and odor, 53 for health contaminants such as lead, 401 for emerging contaminants), rated capacity and replacement interval, and owner reviews for leaks, poor fit and slow flow. We separate certified claims from a brand’s own lab testing, and we note that most refrigerator filters do not remove fluoride.
We checked certification claims against the standards published by NSF International and the EPA’s guidance on lead in drinking water, and we encourage readers to look up a filter’s model number in NSF’s or IAPMO’s online listings. Our full process is explained on our How We Test page. We do not list prices or star ratings because they change daily.
