No, you cannot boil PFAS out of water. Boiling does not destroy or remove per- and polyfluoroalkyl substances, and it can make the problem worse. As water turns to steam, the PFAS stay behind in the pot, so the chemicals end up more concentrated in whatever water is left.
The Minnesota Department of Health puts it plainly: "Boiling water will not remove PFAS." Several state health agencies, including New Hampshire and Rhode Island, say the same thing. If you are worried about forever chemicals in your tap water, the kettle is not your answer.
Boiling works on some contaminants because heat kills them. It is a reliable way to deal with bacteria, viruses, and parasites during a boil-water advisory. But PFAS are not living organisms. They are extremely stable man-made chemicals built around carbon-fluorine bonds, which are among the strongest bonds in chemistry. That stability is exactly why they are called "forever chemicals." They resist heat, sunlight, and the normal processes that break other substances down.
When you heat PFAS-contaminated water, two things happen. The water molecules evaporate as steam, but PFAS compounds have boiling points far higher than 212F (100C) and stay in liquid form. So the water you boil away leaves its PFAS load behind. Boil a pot down by half and you have not removed the chemicals, you have roughly doubled their concentration in the remaining water.
This matters for everyday habits. Making pasta, reducing a sauce, brewing coffee, or sterilizing baby bottles in PFAS water does not clean the water. If anything, prolonged boiling for cooking can leave a slightly more concentrated residue. To understand which contaminants are actually in your local supply, start with our home page water lookup and check what the EPA data shows for your ZIP code.
Three filtration technologies have real evidence behind them. The EPA and state health departments point to the same short list.
Whatever you choose, look for independent certification. The Minnesota Department of Health recommends products certified to NSF/ANSI 53 for filters or NSF/ANSI 58 for reverse osmosis. A filter that is not certified to reduce PFAS specifically may do nothing for them, even if it improves taste. Our PFAS filter guide walks through certified options.
Distillation does remove PFAS, because it captures the evaporated water and discards the concentrated residue, but it is slow, energy-hungry, and impractical for daily home drinking water. It is not the same as boiling. Boiling without capturing and discarding the steam leaves you worse off. Freezing water does nothing useful for PFAS either.
The short version: heat is the wrong tool. PFAS removal is a physical filtration problem, not a temperature problem.
The EPA set its first legally enforceable national drinking water limits for PFAS in 2024, including a maximum contaminant level of 4 parts per trillion each for PFOA and PFOS. Those numbers are low because the health concerns, which include effects on the immune system, cholesterol, and certain cancers, show up at very small exposures. You cannot taste, smell, or see PFAS, so the only way to know your levels is testing data.
Before you spend money on any filter, find out whether your water actually has a PFAS problem and at what level. Look up your area on our PFAS overview page or enter your ZIP code on the home page to see what regulated contaminants the EPA has recorded for your system. That tells you whether you need an RO system, a certified carbon filter, or nothing at all.
### Does boiling water remove any forever chemicals? No. Boiling does not remove any PFAS compounds. Because the chemicals stay behind as water evaporates, prolonged boiling can leave them at a higher concentration in the remaining water.
### Is it safe to cook with PFAS-contaminated water? Cooking with contaminated water does not remove PFAS and may concentrate it in reduced liquids like sauces or stocks. If your water has confirmed PFAS above EPA limits, use filtered water for cooking and drinking, not just for drinking glasses.
### Will a Brita pitcher remove PFAS? Standard activated-carbon pitchers can reduce some PFAS, but effectiveness varies and drops as the cartridge ages. Look for a pitcher or filter independently certified to NSF/ANSI 53 for PFAS reduction rather than assuming any carbon filter handles it.
### What is the best way to remove PFAS at home? Reverse osmosis is the most thorough home option, removing 90 to 99 percent of PFAS, followed by certified activated carbon and ion exchange systems. Choose products certified to NSF/ANSI 53 or 58.
### How do I know if my water has PFAS? You cannot taste or smell PFAS, so you need data or a lab test. Check the EPA contamination records for your area using your ZIP code, then consider a certified PFAS lab test if your system shows detections.
The next step is simple. Enter your ZIP code on our home page to see whether the EPA has logged PFAS or other contaminants in your water, then match the result to a certified filter instead of reaching for the kettle.
