Every sample is run by a single lab that’s been analyzing water for over six decades, not a fragmented network of subcontractors. - We don’t sell the treatment.
We take no commission on the filters or treatment we recommend. We tell you what’s in your water and how to treat it, with no stake in which filter or product you choose. - Built with a scientific advisory board.
We partner with with leaders in exposomics, chemistry, toxicology, and exposure science deciding what we test for, our thresholds and hazard indexes. - Logistics built for health diagnostics.
Next day UPS Healthcare shipping keeps your sample viable from your tap to the lab. - Lab-grade bottleware.
Lot controlled and pre-sterilized PFAS-free Nalgene and analytical-grade glass, so the container never contaminates the result.

"There’s even a little holder in the box for your phone so you can be hands-free… It truly couldn’t be easier to collect your sample.”

“We had a filter and assumed our water was fine. Then our ROSE results came back with arsenic. When we looked into it, our filter doesn’t even treat arsenic, or most of the other contaminants we found. Now we actually know what we’re dealing with.”

“Ever since I moved into this apartment, my hair has been super coarse and I think it’s in the water. I want to get an accurate read on my water for my hair, but also for my overall health.”

"We drink it every single day. I cook with it, our dogs drink it, and pretty soon we’ll be using it for our baby. But I genuinely could not tell you what was actually in our tap water."

“The test only takes three minutes, which is really fast… We’ll see if New York City water is truly drinkable or not.”

"A filter without a test, it’s just a guess. You can’t optimize your health if your water is working against you"
