For those who've read far enough to know why it matters.

Three contexts, honestly. First: if your daily session is fifteen minutes or less and you need to reach tissue saturation in that window. Second: if you're building a structured longevity protocol with specific higher-dose targets. Third: intensive recovery contexts — elite athletic, post-operative under medical guidance, or similar. For a standard 30–60 minute daily practice, the Nova does the same job at nearly half the price.

Probably not, unless one of the three contexts above applies. The difference in real-world benefit between the Nova (at a standard session length) and the Medic is small enough that most people find the Nova delivers everything they need. Buying the Medic "to be sure" usually means paying for output you'll never use. We'd rather point you at the right machine than the biggest one.

Fifteen minutes is often enough. At 3,000 ml/min, tissue saturation is reached quickly; sustained sessions beyond that point add diminishing benefit for most people. Longer sessions are fine and sometimes called for in specific protocols — the machine is rated for continuous run up to 8 hours. The question is usually not how long, but whether you need this level of flow in the first place.

Flow rate — twice the Nova, at 3,000 ml/min. Physical format — larger chassis, twin-tank architecture, castors for mobility. Session character — built for sustained high-output use, suited to treatment rooms or dedicated home installations. Everything else is shared: same USA-manufactured PEM membrane, same 2-year UK warranty, same direct UK support, same care from the same team.

Yes. The Medic's chassis, castors and handles are designed for mobility between treatment spaces. Several H2 Pure Life customers use it in osteopathic, longevity-clinic or private-practice contexts, always alongside the standard disclaimer that the machine is a wellness device and is not classified as a medical device in the UK.

Distilled or deionised water only. Tap water contains minerals that shorten the life of the electrolyzer considerably — this is true across the whole range, but matters more on the Medic given the higher consumption rate. The TDS pen included in the box confirms water purity before each refill.

Noticeably louder than the Nova at peak flow, given the twin-tank architecture and the higher output. Still well within the range of a comfortable treatment space or home office. Not a machine you'd place beside a sleeping partner.

Yes. We offer Klarna and Clearpay at checkout, both interest-free. The Hydro Medic works out at around £1,188 per month over four months with Clearpay, or three monthly payments with Klarna. If you'd rather arrange something different, our UK team can help — just email us.

Email our UK team. We handle warranty directly — no international returns, no grey-market complications, no going through a distributor. If a repair is needed, we arrange collection and cover postage both ways for the first two years. The Medic's service record is excellent; in the rare case of an issue, we aim to turn it around inside a week.
