Water Filtration
Systems in Raleigh, NC
Raleigh's water is disinfected with chloramine and carries disinfection byproducts and PFAS. We test your water free in your home, then install the whole-home filtration, softening and drinking-water systems that fit it.

Quick answer
What's in Raleigh tap water?
EWG's Tap Water Database flags contaminants above its health guidelines in Raleigh water, led by Haloacetic Acids at 332× the guideline, along with Total Trihalomethanes, Bromodichloromethane and PFOS. Whole-home carbon filtration reduces disinfection byproducts at every tap, and reverse osmosis removes PFAS and heavy metals from drinking water. Our free in-home water test shows your own numbers.
What's In Raleigh's Tap Water?
Raleigh water meets federal legal standards, but EWG found contaminants far above science-based health guidelines. Hover or tap one to see where it hits the body.

A trihalomethane byproduct associated with cancer risk and harm during pregnancy.
Accumulates in the body permanently; linked to cardiovascular disease and fetal development harm.

Common Raleigh Water Problems
And the systems we use to solve them.
Disinfection Byproducts
Raleigh's surface water is treated with chlorine, which reacts with organic matter to form TTHMs and HAAs — detected at up to 332× EWG's health guidelines.
Our solution
Whole-home carbon filtration + reverse osmosis removes DBPs at every tap and at the point of drinking.
Chloramine Taste & Odor
Raleigh disinfects with chloramine, chlorine bonded with ammonia. It lasts longer in the pipes than plain chlorine, and each spring the city switches to straight chlorine for about six weeks, when many homes notice a pool smell.
Our solution
Whole-home catalytic carbon filtration breaks down chloramine and chlorine at every tap, so showers, laundry and cooking water stop smelling treated.
PFAS "Forever Chemicals"
PFOS and PFOA have been detected above EWG's health guidelines. These chemicals accumulate in the body and never break down in the environment.
Our solution
Reverse osmosis is the most effective technology for removing PFAS from drinking water.
