Check what’s in your tap water.

Enter your ZIP code. We pull your water system’s official EPA records: lead test results, health-based violations and where your water comes from.

Free, no sign-up. Try

Your report shows the latest lead results against the federal action level, any health-based violations from the last 10 years, your water source, and which filter type fits.

Data: US EPA Safe Drinking Water Information System (SDWIS), updated quarterly, so the newest results can lag by a few months. On a private well? Utilities don’t test wells: see our well water guides.

Start from your situation

Most people need one specific fix, not the most expensive system. Pick the one that sounds like your home and the finder fills in for you.

How we decide what to recommend

Certifications over claimsWe match products to independent NSF/ANSI certifications, not to what the box says.
No pretend testingWe compare published specs and certification data. We never claim to have tested a filter ourselves.
Commissions never set the orderSome links may earn us a commission. Rankings come from fit for your water, and every pick lists its downsides.
