EWG’s guide to PFAS water filters: “What’s in your water? The “forever chemicals” known as PFAS contaminate the drinking water and groundwater of more than 2,800 communities, affecting an estimated 200 million Americans. Simply drinking a glass of water from your kitchen tap may expose you to these toxic substances – but there are steps you can take to protect yourself and your family. One way to reduce harmful forever chemicals in your home is to use a water filter rather than drink straight from the faucet. But with so many filters on the market, and many marketing claims about eliminating PFAS, it can be hard to know which one is best for your home. EWG’s guide to PFAS filters is based on our experience with several brands. EWG staff bought and used 10 different types of water filters, testing them in real homes using their water. We measured how much each water filter reduced forever chemicals. To bring you our recommendation, we also accounted for several other important qualities in our top selections. including the cost of the filter and its potential useful life, among other considerations.”
