North Carolina PFAS: How's the Water in My Neighborhood?
North Carolina is known for PFAS (per- and polyfluoroalkyl substances) in the Cape Fear River. But levels vary widely by area. Check the actual readings for the Triangle and Charlotte in each water agency's latest report.
The gold line at the end of each bar marks the EPA's 4 ppt standard for PFOA/PFOS; compliance is judged on annual averages, not individual readings. Cary figures are from the 2025 report; Charlotte's 2025 report lists no PFOA/PFOS detections.

How to Choose a Home Filter
The EPA notes that reverse osmosis (RO), activated carbon, and ion exchange filters can reduce PFAS. It recommends checking whether a product is NSF/ANSI 53 or 58 certified for PFAS reduction.
Filter Care Is Performance
The EPA stresses that filters only work when maintained as the manufacturer directs. With a Coway rental, a specialist visits every 6 months to replace them.
Check Certifications by Model
Coway purifier models carry different certifications. If PFAS worries you, we'll walk you through each model's certifications during your consultation.
These figures are system-wide data published by the agencies; actual water quality at your home may vary by water provider and building plumbing. For Raleigh, Durham, Greensboro, and other areas, check your local water provider's annual quality report.

Charlotte Tap Water Is Soft: Purifier Before Softener
Charlotte Water's 2025 report lists total hardness at 32 ppm (about 1.9 gpg) — soft water. Scale is rarely a concern, so a drinking-water purifier comes first for most households.
Charlotte disinfects with chlorine; Cary uses chlorine and chloramine. Both stay within safety standards, but a purifier helps if you're sensitive to taste and odor.

Do you install in Cary or Morrisville too?
Yes — installation is available across the Triangle, including Cary and Morrisville, as well as Charlotte. For Greensboro and Winston-Salem, send us your address and we'll confirm availability.
Is there PFAS in North Carolina tap water?
It varies by area. Cary's 2025 report showed PFOA averaging 1.3 ppt, below the federal 4 ppt standard, and Charlotte's report listed no PFOA/PFOS detections. Wilmington, downstream on the Cape Fear River, has been removing PFAS with a large granular activated carbon facility since 2022.
Can a water purifier reduce PFAS?
The U.S. Environmental Protection Agency notes that reverse osmosis, activated carbon, and ion exchange filters can reduce PFAS. But PFAS-reduction certification varies by model, so we'll verify each model's certifications during your consultation.
Do I need a water softener in North Carolina too?
Charlotte tap water is soft at 32 ppm total hardness, so most households don't need a softener. Homes on private wells should decide based on a water test.
How are filters maintained after installation?
During your rental, a Coway specialist visits every 6 months to replace filters and inspect your products. Maintenance is included in your rental fee.
