The Importance of Water Filtration in St. Louis-Area Homes

Most Missouri and Illinois municipalities meet EPA safety standards, but those standards allow for trace levels of chlorine, chloramine, disinfection byproducts, and — depending on your city's source water — varying amounts of hardness minerals. None of that makes your water unsafe by regulation, but it does affect taste, skin, hair, and the lifespan of your plumbing and appliances.

Well water is even more common the further you get from the St. Louis core — Warren, Franklin, and Ste. Genevieve counties in particular. Missouri's limestone karst geology means well water here tends to run hard, often with iron or sulfur, none of which municipal treatment ever touches since well water isn't treated by the city at all.

A whole-home filtration or softening system doesn't replace your city's treatment — it picks up where it leaves off, addressing the things municipal treatment isn't designed to solve: taste, hardness, and residual chlorine.

The first step for any home is a simple water test. It tells you exactly what you're dealing with, so you're not paying for a system that solves a problem you don't have — or missing one that you do.
