PFAS AND DRINKING WATER:CHOOSING A FILTER
% removed % left over
No filters will remove all PFAS from your water,but with regular maintenance, ANY filter will bebetter than no filter at all.
Filters are better atremoving "long-chain" PFAS
(larger compounds) than"short-chain" PFAS
Reverse osmosis performs
better than activatedcarbon filters
What you can do: Filter your drinking water
Some filters perform better than others...
Regular maintenance is importantThe best way to limit PFAS exposure in your drinking water is by
replacing filters and other parts on time

What about whole-home filtration? Contaminateddrinking water poses the greatest exposureconcern. Consider focusing on water from thekitchen taps and your refrigerator if you arelooking to filter your water.

PFAS (per- and polyfluoroalkyl substances) are a group of persistent, industrialchemicals released into the environment through spills and waste products.Contaminated drinking water is one of the main ways people are exposed to PFAS. Some PFAS can stay in people’s bodies for a long time. Health effects of PFASare not fully understood, but they have been linked to some cancers, highcholesterol, and developmental and reproductive health concerns.
