WHAT PEOPLE ARE SAYING
★★★★★

I had no idea my water had PFAS above the federal limit. Checked my ZIP, saw the report, ordered a filter that same night.

Sarah M.
Columbus, OH
★★★★★

Finally a site that shows real EPA data instead of just trying to sell me something. The score made it immediately clear my water was a problem.

David K.
Phoenix, AZ
★★★★★

Moved to a new city and checked the water before I even unpacked. Three open violations. Bought a filter before my first glass.

Priya S.
Chicago, IL
★★★★★

My daughter has been drinking this water for two years. Seeing the lead risk on here convinced me to get a filter immediately. Should have found this sooner.

Marcus T.
Baltimore, MD
★★★★★

We’re on a tight budget, so “free” mattered. Same EPA numbers I’d dig for myself, but in one screen — I finally understood what to filter for.

James R.
Denver, CO
★★★★★

I compared our report to the utility’s PDF and it lined up. Gave me confidence to pick an RO system instead of guessing off a blog post.

WHY WATERCHECKUP IS DIFFERENT

Your water might look clean. That doesn't mean it is.

PFAS "forever chemicals" have been detected in 45% of US tap water. Lead, disinfection byproducts, and arsenic are often invisible, odorless, and tasteless. Most water quality checkers tap one database — we combine five, translate it into plain language, and match it to the right filter for your home. No login, no paywall, ever.
