2026 water safety guide

Does boiling water remove contaminants? It kills germs, not chemicals.

Boiling is the right move during a bacterial boil-water advisory, and this summer has brought a wave of them after main breaks. But boiling does not remove lead, PFAS, or other chemicals, and it can even concentrate them. Here is the honest division of labor.

The quick picture

Boiling is excellent at killing living things in water. It does almost nothing for the chemicals dissolved in it.

Boiling water is one of the oldest safety steps we have, and it works, for one specific job. A rolling boil kills the bacteria, viruses, and parasites that can make you sick fast. That is exactly why utilities issue boil-water advisories after a main break or a drop in pressure, and this summer has produced a steady run of them, from Anson County, North Carolina and West Columbia, South Carolina to southern Prince George's County, Maryland, all in early July 2026. The trouble starts when people assume boiling also cleans up everything else in the water. It does not. Lead, PFAS, nitrate, pesticides, and disinfection byproducts are chemicals, not living organisms, so heat leaves most of them untouched. Worse, as steam rises out of the pot the water volume shrinks while the chemical mass stays put, so the concentration of something like lead in what is left can actually creep upward. Boiling and filtering are two different tools for two different problems.

Pb PFAS

Heat kills bacteria and parasites

But lead, PFAS, and nitrate remain

Steam can concentrate what is left

Boiling is a microbiology tool.

A rolling boil for one minute, or three minutes above 6,500 feet, reliably kills bacteria, viruses, and parasites like Giardia and Cryptosporidium. That is the exact job a boil-water advisory asks of it.

Chemicals are not alive, so heat does not touch them.

Lead, PFAS, nitrate, and pesticides are dissolved chemicals. Heat cannot break most of them down, so they pass straight through a boil essentially unchanged.

Evaporation can make it worse.

As steam leaves the pot the water volume drops but the chemical mass does not, so the concentration of lead or PFAS in what remains can actually tick upward.

What boiling leaves behind

Boiling kills what is alive. Lead, PFAS, nitrate, and byproducts stay in the glass.

Think of it as a line between biology and chemistry. Boiling works on biology: it denatures the proteins that keep bacteria, viruses, and protozoa alive, so a full rolling boil makes microbially unsafe water safe to drink. Chemistry is a different story. Lead is a dissolved metal that boiling cannot remove and can slightly concentrate. PFAS were purpose-built to survive heat, so a pot on the stove does nothing to them; the EPA points to granular activated carbon, reverse osmosis, and ion exchange as the treatments that actually work. Nitrate, a common concern in farm-country and private-well water, is likewise unaffected by heat. So if your worry is a bacterial advisory, boil. If your worry is the everyday chemistry of tap water, boiling is the wrong tool, and an activated carbon filter is built for exactly that job.

The simple checklist

Three calm rules for boiling, filtering, and knowing which one you need.

Under a boil-water advisory? Boil.

A main break or pressure loss can let bacteria in; that is a microbiological problem.
Boil for one full minute, or three minutes above 6,500 feet, or use bottled water.
A standard carbon pitcher is not a substitute for boiling during an advisory.

Worried about lead or PFAS? Filter, do not boil.

Boiling does not remove dissolved metals or forever chemicals.
Run cold water and use a filter tested for those contaminants.
Boiling can slightly concentrate them, so it is the wrong tool here.

Just want better-tasting water? Filter.

Chlorine taste, byproducts, and lead are everyday chemical concerns.
Activated carbon is built to reduce them at the tap, no boiling needed.
Replace the cartridge on schedule so it keeps working.

What a filter can honestly do

For the chemistry boiling cannot touch, an activated carbon block is the right tool.

Boiling handles the living things; a carbon block handles the chemistry it leaves behind. Activated carbon reduces chlorine taste and odor by adsorption, the aesthetic effect covered by NSF/ANSI Standard 42, and Pure XP is NSF certified to Standard 42 along with NSF/ANSI/CAN 372 for lead-free materials. Beyond taste, the same carbon fiber block is independently lab-tested to reduce 99.9% of lead, evaluated against NSF/ANSI 53, and tested against the NSF/ANSI P473 protocol for PFOA and PFOS, the two most-studied PFAS. Those performance results are independently tested, not NSF certified, and Epic keeps that distinction clear. One honest boundary matters most here: a carbon drinking-water pitcher is not a microbiological purifier. During a bacterial boil-water advisory you should still boil or use bottled water and follow your utility, because a filter reduces chemicals and taste, it does not replace disinfection.

Adsorption The carbon fiber block adsorbs chlorine, byproducts, and organic chemicals as water flows through, the chemistry that boiling leaves behind.

Quick answers

Boiling and filtering FAQ, minus the wall of text.

Does boiling water remove contaminants?

Boiling is very good at one thing: killing living things like bacteria, viruses, and parasites. That is why utilities issue boil-water advisories after a main break or a loss of pressure. But boiling does not remove chemical contaminants such as lead, PFAS, nitrate, or pesticides. Because some water leaves as steam, boiling can even concentrate those chemicals slightly. Boiling and filtering solve two different problems.

Does boiling water remove lead?

No. Lead is a dissolved metal, and boiling does not remove it. Since a little water leaves as steam, boiling can slightly raise the lead concentration in what is left in the pot. To reduce lead at the tap, run cold water and use a filter tested for lead reduction. Epic's Pure XP is independently lab-tested to reduce 99.9% of lead and evaluated against NSF/ANSI 53 criteria.

Does boiling water remove PFAS, the forever chemicals?

No. PFAS were engineered to resist heat and breakdown, so boiling does not destroy them, and concentrating the water can make levels worse. The EPA recognizes granular activated carbon, reverse osmosis, and ion exchange as PFAS treatment methods. Pure XP's carbon block is independently tested against the NSF/ANSI P473 protocol for PFOA and PFOS, and carbon must be replaced on schedule to keep working.

If boiling does not remove chemicals, why do utilities issue boil-water notices?

Because those notices are about bacteria, not chemicals. A boil-water advisory is issued when a main break, pressure loss, or contamination could let microbes into the system, and boiling for one minute, or three minutes above 6,500 feet, kills them. A carbon pitcher is not a substitute for boiling during a bacterial advisory, so always follow your utility's instructions until the notice is lifted.

Does boiling remove the chlorine taste?

Partly. Free chlorine is volatile, so boiling or letting water sit uncovered helps it off-gas and the taste fades. But that does nothing for lead, PFAS, or byproducts, and it uses energy every time. An activated carbon filter reduces chlorine taste and odor continuously; Pure XP is NSF certified to Standard 42 for chlorine taste and odor.

What does boiling water not remove?

Boiling does not remove lead and heavy metals, PFAS, nitrate, pesticides, disinfection byproducts, or most industrial chemicals, and it can concentrate them as water evaporates. It also does nothing for hardness or dissolved minerals. Boiling only addresses living organisms. For chemical and taste concerns, a filter is the right tool.

Should I boil and filter, or just filter?

For everyday tap water that is under no advisory, filtering is usually enough for taste and chemical concerns and boiling is unnecessary. During an official boil-water advisory, boil or use bottled water for drinking and cooking and follow the notice, because that is a microbiological problem a standard carbon pitcher is not built to solve. They are complementary tools for different problems.

Ready to make it simple?

Boiling has its place. For the chemistry, filter at your tap.

Boil-water advisories are issued for microbiological risk after events like water-main breaks or pressure loss; July 2026 examples include advisories in Anson County, North Carolina and southern Prince George's County, Maryland. The guidance that boiling kills bacteria, viruses, and parasites but does not remove chemical contaminants such as lead and PFAS, and can concentrate them, follows U.S. CDC emergency water guidance and EPA emergency disinfection resources; boil for one minute, or three minutes above 6,500 feet. The EPA recognizes granular activated carbon, reverse osmosis, and ion exchange as PFAS treatment approaches. NSF/ANSI Standard 42 covers aesthetic effects including chlorine taste and odor. Product claims are based on Epic Water Filters published testing and certification information: Pure XP is NSF certified to Standard 42 and NSF/ANSI/CAN 372, and is independently lab-tested to reduce 99.9% of lead and evaluated against NSF/ANSI 53 and the NSF/ANSI P473 protocol for PFOA and PFOS; these performance results are independently tested, not NSF certified. A point-of-use filter supplements, but does not replace, your utility's disinfection or any boil-water advisory. Product performance can vary by water quality, usage, and filter replacement schedule.
