Water Filtration Systems in Naperville, IL
Naperville's water is Lake Michigan water, treated by the City of Chicago and delivered through the DuPage Water Commission. If you want less chlorine taste, less scale or filtered water at the sink, we test first and recommend only what your home needs.
Water Filtration Systems We Install
What you need depends on what you want to change:
Carbon Filtration
Takes out the chlorine taste and smell, at one sink or the whole house.
Water Softeners
Reduces the minerals that leave spots on glass and scale in water heaters.
Reverse Osmosis
Filtered water for drinking, coffee and ice.
Sediment Filters
Protects fixtures and appliances from grit.
Water Testing
Testing comes first. Naperville's water is treated Lake Michigan water, so most homes don't need heavy treatment. A test at your tap shows hardness and anything else worth knowing, so you only pay for what helps.
Test again if something changes: a new taste or smell, scale building faster than usual or a water heater that failed early.
Water Treatment in Naperville Homes
Naperville buys Lake Michigan water from the City of Chicago through the DuPage Water Commission. The city also keeps emergency wells, which weren't used for drinking water in 2025.
Chlorine Taste
Treated water carries some chlorine to keep it safe through miles of pipe. A carbon filter takes the taste out.
Scale on Fixtures
Lake Michigan water carries hardness minerals. Over years they build up on faucets, showerheads and inside water heaters. A softener slows it.
Low Sodium to Start
The 2025 water report lists sodium at about 9 mg/L, which is low. If you add a softener, it adds some sodium, and an RO system at the kitchen sink takes it back out.
Emergency Wells
Naperville keeps emergency wells in case the Lake Michigan supply is ever interrupted. They weren't used for drinking water in 2025, so the water at your tap was Lake Michigan water all year.

"Edgar's the man. Not only did he install my water heater, but asked to test the quality of the water to see if that could've lead to the damage and the leak of my last water heater. My water was at a 7 on the hardness scale, and it's supposed to be at 2 or 3. So he reccomends a new water softener, and im thankful that he did. [...]"
