FilteredWTRKNOW YOUR TAP WATER

Your tap water

Know your water.

Every tap in Southern California has a public record. We track 293 water systems across 7 counties, and finding yours takes about ten seconds.

How it works

Your ZIP connects to a water system with public test records. Every chemical gets a plain verdict: Good, Caution, or Too High. Then you see the exact fix for each problem, and you can text us for a free in-home water test.

Guides

If your water looks good, we say so and recommend nothing. A filter suggestion only appears when the record gives a reason for one.

Free local water test

See your own water in person before spending money on treatment.

A local FilteredWTR tech screens the water at your faucet for hardness, chlorine and sediment and explains each reading while you watch. The visit is free, and afterward the decision stays yours.
