Our Story

Built in Chicago, for Chicago Water

Chicago Water Filtration started as a small team of licensed plumbers who kept getting asked the same question on service calls: why does the water taste and feel this way? Over more than 10 years we've grown into a full water treatment company serving the city and suburbs, and we've installed more than 1,200 systems in that time — whole-house filters, softeners, and reverse osmosis systems built around the specific water each home actually has.

We're still locally owned and operated. No call centers, no national franchise fees baked into your quote — just a Chicago-based team that shows up, tests your water, and does the work.

Our Values

What We Stand For

Water treatment has a reputation for pushy sales tactics. We built the company to be the opposite of that.

Honest testing, no scare tactics

We test your water for hardness, chlorine, TDS, iron, and pH, and show you the actual numbers. If your water doesn't need treatment, we'll tell you that instead of manufacturing a problem to sell you a system.

Flat-rate pricing

Every quote covers equipment, installation, permits, and haul-away up front. The number we quote is the number you pay — no add-ons discovered on install day.

Our own licensed plumbers

We don't subcontract installs. Every system is installed by our own licensed, background-checked plumbers, so the person who quoted the job is accountable for the work.

Licensing & Insurance

Licensed and Insured in Illinois

Chicago Water Filtration is fully licensed and insured to perform plumbing and water treatment installation work throughout Illinois. Our plumbers are background-checked employees, not subcontracted labor, and every install is covered by our insurance from start to finish.

Service Commitment

Scheduling That Works Around You

Water problems don't wait for business hours, and neither do we.

Same-week installs

Most installs are scheduled within the same week as your water test — no multi-week backlog to get better water in your home.

Evenings and weekends available

We test and install outside standard business hours, including evenings and weekends, at no extra charge.

One team, start to finish

The same team that tests your water quotes the job and installs the system — no handoffs between sales and install crews.
