What is PFAS and how do you remove it from your water?
PFAS — often called “forever chemicals” — are synthetic compounds that don't break down naturally and have been found in water supplies across the country, including parts of California. Reverse osmosis is one of the most effective ways to remove them at home.
What PFAS are
PFAS (per- and polyfluoroalkyl substances) are man-made chemicals used for decades in nonstick cookware, water-repellent fabrics, and food packaging. They're extremely persistent — they don't degrade in the environment or the human body, which is why they're called “forever chemicals.”
Why PFAS matter
In 2024 the EPA set its first enforceable national drinking-water limits for several PFAS compounds, reflecting research linking long-term exposure to health concerns. Because they accumulate over time, reducing exposure through your drinking water matters.
PFAS in California water
PFAS have been detected in a number of California water sources, and testing and regulation are ongoing. Levels vary by supply, so local testing is the only way to know your exposure.
How to remove PFAS at home
Reverse osmosis is one of the most reliable point-of-use methods for reducing PFAS, along with certain high-grade carbon filters. Puragain's multi-stage RO systems combine carbon and an RO membrane to remove up to 99% of contaminants, including PFAS, from your drinking water.
Frequently asked
Does reverse osmosis remove PFAS?
Yes. Reverse osmosis is one of the most effective home methods for reducing PFAS in drinking water.
Do standard carbon filters remove PFAS?
Only high-grade activated carbon reduces PFAS effectively, and not as reliably as reverse osmosis. Basic pitcher and fridge filters are not designed for it.
Does boiling water remove PFAS?
No. Boiling does not remove PFAS — it can actually concentrate them as water evaporates.
