From your tap to a clean answer

Most water filter companies skip the testing and sell you something generic. We do the work first.

We send you a test kit

A free sampling kit arrives at your door. You collect a first-flush tap sample in the morning — takes about two minutes — and mail it back in the prepaid envelope.

→ Arrives within 5 business days
02

A certified lab tests it

Your sample goes to a Washington State-certified laboratory. We test for lead, chloramine, TDS, pH, hardness, nitrates, and more — the things that actually matter in Seattle water.

→ Results in 10–14 days

You get a personalized report

We mail you a plain-English results report showing your numbers versus your neighborhood average and EPA limits — with a clear recommendation for exactly what your water needs.

Why older homes need testing

Seattle homes built before 1986 may have lead solder joints or lead service lines. The EPA's lead action level is 15 ppb — but there's no safe level of lead exposure. First-flush testing reveals what's actually coming out of your tap, not just what leaves the treatment plant. Read more about lead in Seattle tap water →

Seattle's water is good — but not perfect

The Cedar River and Tolt watersheds produce some of the cleanest source water in the country. But Seattle switched from chlorine to chloramine in 2008, which is harder to filter and can produce a distinct taste and smell. Internal plumbing does the rest. What about PFAS ‘forever chemicals’? →
