Frequently asked
›How does the Find Your System tool work?
You answer a handful of short questions about your water (where you live, city or well, what bothers you, whether you want whole-house or just drinking water). The tool runs the same editorial decision tree our reviewers use, then layers in real local data (USGS hardness, EWG flagged contaminants) for your city or state to tailor the recommendation.
›Do I have to share my address or email?
No. There is no lead capture, no email field and no account. The city and state step is optional, and you can skip it. Nothing is stored on our servers.
›Where does the local water data come from?
USGS hardness data, EPA compliance reports and the EWG Tap Water Database, re-verified yearly. We never claim an area's water is unsafe or illegal: every system listed meets federal EPA limits. EWG figures are framed as the stricter health guideline.
›Will the tool ever recommend something you do not actually rate?
No. Every recommendation maps to a product we have reviewed editorially. The 'Check Latest Price' button links to the manufacturer; we may earn a commission at no cost to you.
