What Does This Mean For You?
Detecting Arsenic in your water supply does not necessarily mean immediate danger, but long-term exposure -- even at low levels -- carries measurable health risk. Reverse osmosis systems and activated alumina filters effectively reduce arsenic levels.
Our recommendation: View Arsenic filters certified for Illinois water conditions or take our free Water Finder Quiz to get a personalized recommendation.
Filter Arsenic From Your Illinois Tap Water
PureWaterGuys carries NSF-certified filters proven to reduce Arsenic and other contaminants found in Illinois water.

What is Arsenic?
Long-term arsenic exposure is linked to skin, bladder, and lung cancer. The EPA MCL is 10 ppb.
Is Illinois tap water safe to drink?
Water quality varies by city. Of the Illinois systems we analyzed, 1630 detected Arsenic. Most levels are below EPA action thresholds, but long-term low-level exposure carries health risk. Check your city's report above or use a certified home filter as a precaution.
What filter removes Arsenic from tap water?
Reverse osmosis systems and activated alumina filters effectively reduce arsenic levels. See our Arsenic filter options.
Data sourced from EPA-mandated annual water quality reports (Consumer Confidence Reports). Last updated: 2026. Not all systems are required to test for every contaminant.
