The EPA has set the country’s first federal limits on forms of PFAS in drinking water.

The new policy covers six forms of these forever chemicals, and can be enforced by the EPA .

Exposure to PFAS has been linked to health problems, including cancer, hypertension and weakened immune systems.

There are a range of water filters that can target PFAS , but they vary in efficacy.

A reverse osmosis water filter is the most effective tool for removing PFAS.

Activated carbon filters can also reduce levels of PFAS but were found to be less effective, according to a 2020 study.
