Frequently asked questions

Water enriched with molecular hydrogen (H₂), an antioxidant. It goes beyond ordinary hydration.*

Hydrogen helps neutralize harmful free radicals and reduce oxidative stress, a key factor in aging and inflammation. Its tiny size lets it reach deep into cells.*

Aim for 1.5–2 liters of water a day. Many people fill HydroWata 4–6 times a day. Even one glass a day is a good start.

About 1–2 hours in an open glass and up to 3 hours in the closed bottle. For best results, drink it within 15–30 minutes.

Filtered or bottled drinking water at room temperature. Do not use reverse osmosis, distilled or ice-cold water.

Pour in white vinegar or clean water, close the lid and let it sit 30 minutes. Shake for 2 minutes, rinse well and let it dry.

High-quality glass, a food-grade silicone seal, and a 304 stainless steel base with a platinum plate and SPE membrane. Everything is BPA-free.

Fully recharge the battery and try warm (not hot) water. Still no bubbles? Send us a short video and we will help, under warranty.

Try another USB-C cable and check that the charging contacts on the base are clean.

Check that the silicone ring is seated evenly and the glass is screwed tight onto the base. Still leaking? Send us a photo or video.

Test right after the cycle (hydrogen fades within 1–3 hours) and check your tester. Send us a video of the test if it still reads zero.
