St. Charles city water comes off the Missouri River and runs some of the hardest water in the region - typically 18-22 grains per gallon, plus the chlorine used to disinfect it. A whole-home air purification system cleans the air through your existing HVAC - fewer allergens, less dust on every surface, and air that actually feels fresh.
