Five friends from Arlington
A 2025 study in JAMA Network Open linked golf-course pesticides to the water we grew up drinking. That water was legal. It still wasn't something we wanted our families drinking. So instead of buying another case of bottled water, we founded Sanavia in 2025.
What we do
Sanavia sells one system, the Hydra: a tankless, 5-stage under-sink reverse osmosis filter that makes 800 gallons a day, with its own faucet. It ships free anywhere in the U.S., and around DC we can install it for you.
Before we asked anyone to trust it, we tested it. We sent an Arlington home's tap water, and the same water after the Hydra, to an independent accredited lab. Total trihalomethanes, the chlorine byproducts that sit furthest over health guidelines here, fell from 58 ppb to 2.79 ppb. See the full lab results.
Why we publish the data
Tap water can meet every legal limit and still carry contaminants above what health researchers recommend. So we built a water report for every city and county we serve, from EWG and EPA test results, and a zip code lookup that shows what is in yours.
Not sure you need a filter at all? Start with a free water test. We mail a kit anywhere in the U.S., and in Northern Virginia we will test at your tap in person.

Out in the community
We poured filtered water for a record 735 runners at the 2026 Arlington Bunny Hop, a volunteer-run charity 5K for local causes.
