Water Filtration & Reverse Osmosis in Charlotte, NC

Charlotte Water draws from the Catawba River chain, primarily Mountain Island Lake and Lake Norman, and hardness varies from home to home, especially on private wells in outlying Mecklenburg County, which often run hard with iron. The bigger city-water issues are chemical: chlorination byproducts, chromium-6 and PFOA, which a whole-home catalytic carbon filter and an under-sink reverse osmosis system remove. Our free in-home test measures your hardness and more on the spot.

Charlotte Water meets every federal legal standard set by the EPA, so in the regulatory sense yes. But legal and health-protective are not the same thing, and federal limits have not been meaningfully updated in nearly two decades. The Environmental Working Group identifies 10 contaminants above its science-based health guidelines in Charlotte Water, led by haloacetic acids (HAA9) detected at 24.8 ppb against a 0.06 ppb guideline — 413 times over. Also flagged: total trihalomethanes, chloroform, hexavalent chromium, and PFOA. These are largely disinfection byproducts, the tradeoff required for pathogen control in treated surface water. A reverse osmosis system removes over 99% of them before they reach your glass.

Charlotte Water disinfects to keep water safe through thousands of miles of pipe, keeping a chlorine residual that averaged 1.04 ppm in its 2025 report. That residual is what you taste and smell, and it reacts with organic matter from Lake Norman and Mountain Island Lake to form trihalomethanes, which ran as high as 77.4 ppb against an 80 ppb limit. A whole-home catalytic carbon filter removes chlorine and chloramine alike and reduces those byproducts at every tap.

For most Charlotte homes we start with a whole-home catalytic carbon filter paired with an under-sink reverse osmosis system, or our Complete Home System for whole-home coverage in a single install. The catalytic carbon handles chlorine and disinfection byproducts at every tap, which is where the bulk of Charlotte's flagged contaminants sit. The RO then handles what carbon cannot: PFOA, hexavalent chromium, and the remaining trace compounds in the water you actually drink and cook with. If budget forces a starting point, begin with the RO, since it addresses the most health-critical contaminants at the tap that matters most. Homes on private wells in outlying Mecklenburg County are a different case and should start with a test before anything is specified.

Usually yes. We operate out of a Charlotte warehouse at 2420 N Brevard St, so equipment and crews are local rather than dispatched from the Triangle. Call us or submit the form above and we'll schedule a free in-home water test — we bring a kit, run an on-site analysis, and walk you through exactly what is in your water before recommending anything. From there we quote only what your home actually needs, with transparent pricing. Most whole-home filtration and under-sink RO installations complete in a single visit, typically 3–5 hours, and every system carries a lifetime warranty with lifetime phone support. There is no obligation to buy after the free test.
