Description
Velta H₂ · Hhuhu 500 Plus
Hydrogen, delivered with your breath.
The current Hhuhu 500 Plus pairs 500 cc/min hydrogen generation with Breath‑Sync™—holding output between breaths, then delivering it when inhalation begins.
Designed for daily routines with 41 dBA operation, stable 500 cc/min hydrogen output and up to 16 hours of stated runtime from a full tank.
Why molecular hydrogen
Your body manages oxidative stress every day. Hydrogen is worth understanding.
Your body creates reactive molecules every day. At normal levels, they are part of immune defence and cell signalling. But hard training, poor sleep, pollution and other everyday pressures can raise the load faster than the body’s own antioxidant defences can rebalance it.
That is why people are looking at molecular hydrogen. Its very small molecular size and selective antioxidant activity are being studied for their potential to support redox balance and recovery—while preserving the useful signalling the body needs. It is not a shortcut; it is a serious area of research with practical questions still being answered.
Breath‑Sync™ intelligence
Hold between breaths. Release on inhale.
An integrated sensor detects the start of inhalation. Rather than letting the generated gas pass during exhale and pause, Hhuhu 500 Plus stores output, then releases it into the next inhale.
500 cc/min
Hydrogen is generated continuously within the system.
Between breaths
Output is stored while the user is exhaling or pausing.
On inhale
The accumulated output is released when inhalation begins.
The difference, illustrated
More of the generated hydrogen meets the inhale.
In the brochure’s illustrated four-second breathing cycle, a 500 cc/min system produces 9.49 ml during a 1.14-second inhale under continuous flow. Breath‑Sync™ stores output across the full cycle and releases 33.32 ml at the next inhale: a 3.52× illustration of timing, not an individual delivery promise.
Made to be lived with
Quiet enough to disappear into the room.
This is a system designed for the time you already have: a calm evening, a book, a work break. The appliance stays deliberately simple so the focus can remain on the routine.
Engineered delivery path
Three technologies. One protected hydrogen path.
The 500 Plus brings hydrogen generation, moisture management and appliance safeguards together in one compact device.
PEM‑MEA core
A DuPont™ Nafion® solid polymer proton-exchange membrane supports electrolysis from the specified pure water source to create the stated hydrogen stream.
APWS Technology™
Auto‑Physical Water Separation separates moisture before hydrogen reaches the nasal cannula, helping keep the delivery path dry and comfortable.
AMD Platform™
Water-level sensing, thermal management and automatic safeguards are integrated into the appliance platform.
The water requirement
Start with pure water.
Hhuhu 500 Plus starts with a precise input: pure or distilled water. That clean, low‑TDS source is what its hydrogen-generation system is designed to use.
Independent verification
Proof you can check.
Verified where it matters: the supplied reports cover purity, measured flow and electrical conformity, with the report references available to review directly.
Report DNG23B00017
