Which brings us to per- and polyfluoroalkyl substances, commonly known as PFAS. Used in a wide array of commercial applications since the 1950s – think firefighting foam, non-stick pans, and water-repellents – the family of chemicals has come under scrutiny because they accumulate in organisms (like humans) and remain in the environment indefinitely. You may … More What’s the best water filter for removing toxic PFAS?
Key takeaways include: Reverse osmosis filters and two-stage filters reduced PFAS levels, including GenX, by 94% or more in water, though the small number of two-stage filters tested necessitates further testing to determine why they performed so well. Activated-carbon filters removed 73% of PFAS contaminants, on average, but results varied greatly. In some cases, the … More Not All In-Home Drinking Water Filters Completely Remove Toxic PFAS

Of tap water samples from 44 places in 31 states and the District of Columbia, only one location had no detectable PFAS, and only two other locations had PFAS below the level that independent studies show pose risks to human health. Some of the highest PFAS levels detected were in samples from major metropolitan areas, … More PFAS Contamination of Drinking Water Far More Prevalent Than Previously Reported
These chemicals may seem hard to find, but Michelle Plusquin, a study author, told Inverse this year that they are particularly relevant in Flanders, where this study was conducted.
