Single Tap Water Purifier & Instant Hot Water Dispenser

Enjoy safe, clean drinking water at the touch of a button. Our one-tap purification systems combine RO membrane filtration, multi-stage purification, and precise temperature control for everyday convenience.

A VATTI WDHG01 water purifier and its V818WD heater on a marble counter, with the stainless One Tap fitted at the sink beside them.

WDHG01

The WDHG01 is the water purifier we sell

Two boxes under the sink and one tap above it: the WDHG01 filters through four stages to a 0.0001 micron RO membrane, and the V818WD heats on demand, so hot water arrives in three seconds and a glass fills in six. Four temperatures on the tap, 100°C for tea down to room temperature. You change the filters yourself, RM189 a year and RM499 every second year.

6 reasons to buy a VATTI water purifier

Multi-stage first, then RO
Sediment and activated carbon take out the particles and the chlorine. The reverse osmosis membrane behind them takes what is left: heavy metals, bacteria and dissolved solids.
Boiling water on demand
Straight to 100°C at the tap, with no kettle to fill and nothing to wait for. It is the setting that quietly removes an appliance from the counter.
Four temperatures, one fixture
Cold, ambient, 45°C and 100°C, selected at the tap. One fitting replaces the dispenser, the kettle and the jug in the fridge door.
Stainless steel where the water is
The tap and the tank are both SUS 304 stainless rather than plastic. In a system that holds water at 100°C, that is what keeps the water tasting of nothing at all.
It tells you when the filter is spent
A filter change reminder on the display. The thing that decides whether the water is actually being purified is then not left to somebody remembering when it was last done.
Nothing on the counter
The whole system is undersink. In a condo kitchen the worktop is the scarcest thing in the room, and this gives back the corner a dispenser would have taken.

Choosing a water purifier in Malaysia

  • 45-100°C

    Four temperatures out of one tap

    Cold for drinking, ambient, 45°C, and 100°C for tea, coffee and instant noodles. The 45°C setting is not a rounding of "warm": it is the temperature baby formula is made at, which is the reason a household with an infant buys one of these.

  • 1.5L/min

    Enough flow to fill a pot

    Output at the tap is 1.5 litres a minute, so a litre jug takes about forty seconds. That is the difference between a purifier the kitchen uses for cooking and one that only ever fills a glass.

  • What reverse osmosis removes

    RO pushes water through a membrane fine enough to stop heavy metals, chlorine and dissolved solids. It takes some naturally occurring minerals out with them, which is normal for the method and does not make the water less safe to drink.

  • The stages in front of the membrane

    The VPC system runs sediment and activated carbon stages ahead of the RO membrane. They take out the particles and the chlorine taste first, and in doing so they are also what stops the expensive membrane behind them clogging early.

  • It lives under the sink

    The filtration unit and the tank go into the cabinet below. All that shows on the counter is the slim SUS 304 stainless tap, which is why this suits a condo kitchen where a floor-standing dispenser and its bottles would not fit.

  • Filters are the running cost

    The unit tracks filter life and tells you when one is due rather than leaving it to memory, which matters because a filter past its life is a purifier that has quietly stopped purifying. Budget for replacements, and have the dealer do the first change while you watch.

How Water Filters Work: Simple Guide to Safe Drinking Water

The long version: how the types differ, which of the numbers actually decide it, and which one suits the kitchen you already have.

012-3366082 →
Is a single-tap purifier better than a water dispenser?

For most homes, yes. It filters and delivers at four temperatures from one fixture at the sink, with no bottles to refill, no floor space given up, and no waiting for water to heat or chill.

Does reverse osmosis remove minerals?

Some, yes. RO is thorough enough that it takes naturally occurring minerals out along with the heavy metals, chlorine and dissolved solids. That is normal for the method, and the water stays perfectly safe to drink.

Can it be installed under the sink?

That is where it is designed to go. The filtration unit and the tank fit in the cabinet below and only the tap shows above. Use a professional installer so the connection to the supply is made properly.

Can I purify tap water by boiling it?

Only partly. Boiling kills most bacteria, but it does nothing about chemicals, heavy metals or sediment, and it concentrates rather than removes them. Our guide to how water filters work covers the difference.

Is tap water safe to drink in Malaysia?

It is treated to a safe standard when it leaves the plant. What happens between there and your tap varies: old plumbing, local contamination and seasonal changes all affect what arrives.

Do I really need to filter my tap water?

If the water tastes or smells of anything, if the building is old, or if there is an infant in the house, then yes. Otherwise it is a question of how much you want to think about it.

What are the signs of unsafe tap water?

A bad taste or smell, cloudiness or discolouration, visible sediment, and stomach upsets that follow drinking it. Any of those is a reason to stop drinking it unfiltered and find out why.

What is the downside of a water purifier?

The filters are a running cost and they have to be changed on time. RO systems also send some water to drain as part of how the membrane works. Both are the price of the purity, and worth knowing before you buy rather than after.

What should I consider when buying a water purifier?

The quality of the water going in, the filtration type, how much the household actually drinks and cooks with, and what the replacement filters cost over a few years.

Why does reverse osmosis water taste flat?

Because it is very pure and low in minerals, and minerals are most of what water tastes of. It is a matter of what you are used to rather than a fault.

Not sure which water purifier fits?

Send us the kitchen: what you cook, how the space is laid out, and what has to fit where. We will narrow it to one model and the nearest dealer who stocks it.
