Chicago Tap Water: The Problem Is the Lead Pipe Coming into Your Home
Chicago tap water comes from treated Lake Michigan water and meets federal and state standards. But Chicago still has more lead service lines than any other U.S. city, so lead can leach into the water as it passes through pipes in older homes.
If you're concerned about lead, the Chicago water department advises contacting 311 for water testingand runs several lead service line replacement programs.
The gold lines on the two bars mark the action levels (lead 15 ppb, copper 1.3 ppm); both 90th percentiles came in below. The replacement figure is an estimate based on press analysis.

How to Choose a Lead-Reducing Filter
NSF 53
Certification standards for lead-reducing filters
- EPA advises checking for NSF/ANSI 53 testing plus a "reduces lead" claim
- Also look for NSF/ANSI 42 certification for particle reduction
- Coway model certifications available during consultation
If Your Home Is Older
Lead mainly leaches from service lines and indoor plumbing. If your home was built before 1986, check the city's service line lookup or request a 311 test first.
Renters & Condo Residents
Renters can't replace a building's plumbing. In that case, a purifier installed at the kitchen tap is the practical alternative.
Filter Care Is Performance
Filters only perform when replaced on schedule. With a Coway rental, a specialist visits every 6 months to replace them.
Chicago Air: F Grades for Both Ozone and Year-Round Particle Pollution
In the American Lung Association's 2026 report, the Chicago–Naperville area ranked #15 nationally for ozone pollution and #13 for year-round particle pollution, placing it among the country's most polluted metro areas.
Averaging 18 unhealthy days per year (Cook County)
Cook County's annual average exceeds the federal standard
Averaging 3.7 unhealthy days per year
- Rankings are based on the American Lung Association's 2026 report, analyzing 2022–2024 monitoring data.
- The association is especially concerned about residents near warehouses, industrial zones, and major highways.
- Ozone forms when vehicle and factory emissions react in sunlight, and peaks in summer.
What an Air Purifier Can Do
- Reduce fine dust that drifts indoors from road dust and smoke
- Manage indoor air in summer and winter with windows closed
- The U.S. Environmental Protection Agency (EPA) notes that air purifiers cannot remove every pollutant. On ozone alert days, limiting outdoor activity comes first.
Illinois Service Areas
Select a region to see the main cities we service, local installation notes, and frequently asked questions for that area. If your city isn't listed, just share your address and we'll confirm whether installation is available.
Chicago
All of Chicago
- Chicago
This is our highest-volume area for consultations and installs. Many homes here predate 1986, so during consultation we also ask about lead service line status and any 311 testing history.
Can renters get a purifier installed?
Yes. While building-wide plumbing can't be changed, a purifier installed at the kitchen faucet lets you manage your drinking water.
North Suburbs
Korean communities including Glenview and Niles
- Glenview
- Niles
- Northbrook
- Lake Forest
A key suburban area with a high Korean-community density, mixing single-family homes and townhouses. We recommend a model suited to your plumbing layout during consultation.
Do Glenview and Niles use the same water source as Chicago?
Many nearby suburbs purchase treated Lake Michigan water from Chicago's water utility. We'll confirm your exact supplier from your local water utility's notices.
West Suburbs
DuPage · Kane · Will Counties
- Westmont
- Addison
- St. Charles
- Carpentersville
- Plainfield
This broad western suburban area spans several counties. With many new-construction developments like Plainfield, inquiries for built-in and under-sink models are also rising.
Can a built-in unit be installed in new-construction homes in Plainfield?
Yes. New-construction homes tend to have standardized plumbing, which makes built-in model installation relatively straightforward.
McHenry County
Northwest Chicago suburbs
- Crystal Lake
- McHenry
- Oakwood Hills
Outside Chicago's water utility service area, some homes here rely on local groundwater systems or private wells, so we review your water test results together.
Do you install in areas that use groundwater?
Yes. Since groundwater mineral content can vary, we base our product recommendation on your local utility's report or well test results.
Southwest
Will · Grundy · Kankakee Counties
- Crest Hill
- Coal City
- Bradley
- Newark
An outlying southwestern area farther from the branch. For farther towns like Bradley and Newark, we group visits with nearby areas for efficient scheduling.
Does this area still get 6-month maintenance visits?
Yes, as long as your area is serviceable you'll get the same 6-month visit schedule, coordinated together with nearby areas.
Northwest
Rockford and DeKalb areas
- Rockford
- DeKalb
- Lee
The farthest northwest outlying area from Chicago. For addresses near or beyond the 70-mile radius, we'll confirm visit availability during the consultation.
Do you install in farther areas like Rockford?
If your area is serviceable, you'll get the same installation and 6-month maintenance terms. Since it's farther from the branch, visit scheduling needs to be coordinated in advance.
Installation may be difficult in areas more than 70 miles from a Coway branch or authorized dealer.

Do you install in Glenview or Niles too?
Yes — installation is available in Chicago's northern suburbs, including Glenview and Niles, as well as downtown Chicago and western suburbs like Westmont. For other areas, send us your address and we'll confirm availability.
Is there lead in Chicago tap water?
Tap water meets the standards — the 2025 lead 90th percentile was 8.2–9.4 ppb, below the 15 ppb action level. But with over 400,000 lead service lines still in Chicago, older homes should call 311 to request a water test.
Can a water purifier reduce lead?
The U.S. Environmental Protection Agency advises checking for filters certified to NSF/ANSI 53 for lead reduction. Coway purifiers carry different certifications by model, so we'll walk you through each model's certifications during your consultation.
How bad is Chicago's air?
In the American Lung Association's 2026 report, the Chicago–Naperville area ranked #15 nationally for ozone and #13 for year-round particle pollution — both F grades. In seasons when you keep windows closed, an air purifier can help manage indoor fine dust.
How are filters maintained after installation?
During your rental, a Coway specialist visits every 6 months to replace filters and inspect your products. Maintenance is included in your rental fee.
