Daily operation
How to prepare and maintain Hhuhu.
Fill the removable tank with compatible purified water, dispense on demand and clean the tank every two weeks.
02
Fill and seat the 3 L tank
Remove the rear tank, fill it, and return it firmly to the slot. Keep enough space behind the 476 mm-deep machine for this movement.
03
Dispense a glass
Place a glass below the outlet and press the dispense button. The cycle stops automatically after about 15 seconds, or press again to stop sooner.
04
Clean the tank every two weeks
Every two weeks, wash with mild detergent, rinse thoroughly and air-dry before reinstalling. Wipe—not immerse—the powered base.
The temporary white cloud
Watch the fine bubbles form.
Fine bubbles give freshly dispensed water a milky-white appearance. The water clears naturally as the bubbles rise.
The cloud shows the suspended bubbles. Dissolved hydrogen is measured separately.
Hydrogen measurement
How to read Hhuhu's hydrogen output.
Hhuhu's headline figure combines dissolved hydrogen and suspended bubble form. For a direct product comparison, use dissolved-H₂ readings taken under equivalent conditions.
- Published figure
- Over 10,000 ppm · labelled combined dissolved + bubble form
- How to read it
- A combined dissolved-plus-bubble figure
- Bubble-size figure
- Approximately 163 nm · manufacturer test
- 24-hour figure
- Bubble count under the manufacturer's test conditions
- Visible white cloud
- The visible effect of suspended micro- and nano-bubbles
- Best direct comparison

Source-water requirements
Use compatible purified water.
Hhuhu has no tap-water filter and requires purified, distilled or RO source water within the specified operating limit.
01
Purified source water
Start with purified, distilled or RO water at TDS 5 or below.
02
Fill the removable tank
The 3 L rear tank is removable for filling and fortnightly cleaning.
03
Prepare hydrogen water
Press once to begin a dispense cycle of about 15 seconds.

Why the water looks cloudy at first
Fine bubbles give the water a milky appearance as it dispenses. It clears naturally as the bubbles rise.

Frequently asked questions
Hhuhu FAQs.
01Is Hhuhu a water purifier?
+
No. Hhuhu enriches compatible source water with molecular hydrogen; it does not filter Singapore tap water. It requires purified, distilled or RO water within the operating limit, plus a separate purifier if the household does not already have a suitable source.
02Can I use tap, mineral or alkaline water in Hhuhu?
+
Hhuhu requires purified, distilled or RO water with TDS of 5 or below. Tap, mineral and alkaline water can affect performance and internal components.
03What does the temporary white appearance mean?
+
It comes from micro- and nano-sized bubbles suspended in the water and fades naturally as gas is released. Dissolved-H₂ concentration is measured separately.
04Is the 10,000 ppm figure dissolved hydrogen?
+
It is a combined dissolved-plus-bubble figure, not a direct dissolved-H₂ reading. For a useful comparison, look for the same measurement method, source water, temperature and time after dispensing.
05What should I do if the red indicator stays on?
+
Check the tank level and seating first. If there is enough water, place an empty cup below the outlet, hold RESET for two seconds and allow the purge to run for about 20 seconds. If the issue continues, stop using the machine and contact Velta Singapore support.
06How often does the tank need cleaning?
+
The manual recommends cleaning the removable tank every two weeks with mild detergent, followed by a thorough rinse and air-dry. Wipe the main unit with a soft damp cloth; do not immerse it or use alcohol, solvents or abrasives.
07Does Hhuhu need replacement filters?
+
No scheduled replacement filter is required. The removable tank needs fortnightly cleaning, while other servicing is handled as needed.
08What does research say about hydrogen water?
+
Human research is still developing and uses varied devices and protocols. Hhuhu is a wellness appliance, not a treatment for disease; speak with a qualified clinician about medical decisions.
