Why Seattle Residents Choose Coway
Local Water Quality: What the Data Shows
Seattle has some of the softest municipal water in America β about 22 ppm (1.3 grains per gallon) from the protected Cedar River and Tolt River watersheds in the Cascades. Scale buildup isnβt the issue here; taste is. Trihalomethanes (chlorination byproducts) run 15β53 ppb in SPUβs monitoring β below the 80 ppb federal limit, but exactly the kind of compound the EWG flags against stricter health benchmarks.
Seattleβs source water has no detectable lead β but older Seattle homes can add it through their own plumbing, which is why filtering at the tap matters even with excellent source water. Curious why Korean purifier technology is catching on here? Read our Seattle deep dive.
