We follow the science. Not trends. Not fear.
We’ve partnered with the leading researchers, scientists, and clinicians in exposure health, along with the most advanced labs in the country, and built ROSE with them.
These experts shape what we test for, and how we measure it, and the solutions we recommend. We add a carefully considered layer of hospitality on top to help deliver important information in a way that is easy to understand and act on.
Our scientific advisory board.
Our science board is made up of leading experts in exposure science, epidemiology, toxicologists, green chemistry, analytical chemistry, family medicine, and exposomics. These practitioners determine what we test for, how we weigh each toxin, and what guidance we share with you.

Our lab partners
We’ve partnered with one of the top water testing labs in the country to develop proprietary methods that enable us to bring industrial-grade testing to your home.
Every water sample is analyzed at our partner ISO-certified lab run by one of the country’s leading experts in PFAS analysis. We measure with the most advanced instruments, revealing detail that a test strip can’t see. Most kits can’t either.
We hold your water to a higher standard
Official safety limits are not always aligned across organizations. Some protect health. Others reflect what utilities can manage. We hold your result to the strictest health-based standard among the EPA, WHO, California, and the EU.
Take lead as an example. The health goal is zero. But no utility has to act until 15 ppb (10 by 2027). Legal and safe are not the same thing.
We’re also honest about the evidence and regularly add the latest discoveries linking contaminants to health concerns. For every contaminant, we tell you what’s well established and what’s still emerging, so you know how to weigh it.
What we test for and why it matters
100+ contaminants, across six classes.

Aluminum – Impairs brain development
Arsenic – Impairs brain development
Copper – Impairs brain development
We don’t stop at a number
A result isn’t the end. Every finding comes with what it means and what to do to reduce exposure and protect your health.
Fix what matters, then retest to prove it worked.
Test
Fill the bottle at your tap or shower, drop it in the prepaid mailer. Takes 3 minutes.
Fix
Get a full breakdown from a leading ISO-certified lab, plus a fix matched to your results.
Retest
Confirm your fix worked. You only retest what your results flagged.
