Comparing drinking water options, many Hong Kong homes and offices search for the water distiller: is making your own distilled water really better than ordering water, buying barrelled water or installing a filter? To answer that, first be clear what a water distiller actually is, its pros and cons, its upkeep and where it fits.
This article focuses on the water distiller itself: how it makes water, its strengths, its limits, its upkeep, and where it does and does not fit — so you know its character before deciding.
Quick answer: is a water distiller right for you?
- Suitable for: Households or workplaces with small, specific uses that can accept the production time and power draw.
- Less suitable for: Busy offices, schools, clinic pantries or venues needing hot and cold water on demand.
- What to check before buying: Production speed, power use, taste and cleaning upkeep — set against your actual usage.
What is a water distiller?
A water distiller heats the source water until it evaporates, then condenses the vapour back into liquid. The process removes most solutes that do not travel with the steam, so the distilled water produced is of high purity.
Distilled water is common in certain laboratory, medical, appliance and other designated uses. But everyday drinking water is not chosen on purity alone — output speed, energy cost, storage, taste and upkeep all count, and these are exactly where the distiller is most easily overestimated at home or in the office.
The strengths of a water distiller
- High purity: suits certain uses that need low-solute water.
- No dependence on barrelled water: water is made on site, reducing external delivery arrangements.
- Good for small, specific uses: certain small equipment or special requirements, for example.
The drawbacks and limits of a water distiller
For everyday drinking in a Hong Kong office or home, the distiller runs into several practical limits:
- Production takes time: evaporation and condensation are slow, and rarely keep up with several people wanting water at once.
- Higher power use: heating to evaporate and then condensing leans on electricity more than ordinary filtration.
- A flat taste: with the minerals almost entirely removed, some people never take to drinking it long term.
- Still needs cleaning: the body, limescale and storage container all need regular attention.
- May not meet hot-and-cold needs: offices usually want cold, warm and hot water — a distiller alone rarely covers it.
Maintaining a water distiller
A distiller makes water on site, and how well it is maintained shows directly in output, taste and lifespan. Watch for:
- Descale regularly: evaporation deposits minerals in the heating chamber — descale per the manual or efficiency suffers.
- Clean the storage container: the finished water usually sits in a storage tank, which needs regular washing rather than long standing.
- Watch consumables and parts: some models have a pre-strainer or activated carbon post-treatment — replace per the guidance.
- Watch the output: markedly slower production usually means scale build-up or ageing parts — deal with it early.
Beyond the distiller: what are the alternatives?
If your goal is not small amounts of high-purity water but steady, convenient, manageable daily drinking water, the distiller is rarely the most convenient answer. The common alternatives are RO (reverse osmosis) dispensers, RO filters and ultrafiltration dispensers — better suited to many users, long-term use and hot and cold water on demand.

Offices and homes in Hong Kong: where does the distiller sit?
The usual pantry problems in Hong Kong offices are limited space, several people at once, hot and cold water needs, and administrators who would rather not manage deliveries and storage. If a distiller cannot make water fast enough, it simply runs short — so it fits small, designated uses, not the main supply of a pantry.
At home, a distiller can be considered for small designated uses; but if the goal is daily drinking, cooking, tea and fewer water purchases, a home RO filter or countertop dispenser is usually more convenient.

Alternatives to consider from Bio-Link
Bio-Link was established in Hong Kong in 1997 and has long provided consultation, installation and maintenance for water filters, RO dispensers and hot-and-cold equipment. If you are weighing up a distiller, consider these directions by home or commercial setting:
ST1523 Upright RO Three-Temperature Water Dispenser
ST1523 suits medium and large office pantries, with RO filtration and three-temperature supply for many users over the long term. For businesses, a fixed maintenance arrangement also cuts the administrative weight of deliveries, storage and sudden shortages.
ST9102 Upright RO Three-Temperature Water Dispenser
ST9102 suits schools, educational institutions and shared venues with steady traffic — especially where durable operation, stable cold-warm-hot supply and documented regular maintenance matter.
STC15 RO Chilled-and-Hot Freestanding Dispenser (Slim)
STC15 suits small offices, clinics and commercial venues short on space, covering RO filtration and hot and cold needs.
RO838 RO water filter
RO838 suits home kitchens for daily drinking and cooking — an RO filtration option without a full-size dispenser.
DT400 Tabletop Instant-Hot Water Dispenser
DT400 suits households and small spaces wanting a countertop hot-and-cold unit, with filtration configured to the site.
Frequently asked questions
What is a water distiller?
A water distiller heats the source water until it evaporates, then condenses the vapour back to liquid, removing most solutes that do not travel with the steam and producing distilled water of high purity.
Does a water distiller suit an office?
It comes down to volume and speed. A distiller needs time and electricity to make water; where many people drink daily or hot and cold water is wanted, an RO dispenser or office water dispenser is usually easier to manage long term.
Does a water distiller use much electricity?
It heats water to evaporation and then condenses it, which leans on electricity more than ordinary filtration. Actual consumption depends on the model, output and frequency of use.
Does a water distiller need maintenance?
Yes. Evaporation deposits scale in the heating chamber, and the storage container needs regular washing; some models carry pre- or post-treatment consumables to replace per guidance. Skimp on upkeep and output slows while taste suffers.
Is a water distiller the same as a water filter?
No. A distiller makes water by heating, evaporating and condensing; a filter treats water through cartridges, an RO membrane or a UF membrane. Different principles, different places.
Does Bio-Link sell water distillers?
Bio-Link mainly provides water filters, RO dispensers, hot-and-cold equipment and direct-drinking taps. If you are weighing a distiller, first assess whether an RO or UF option fits better against headcount, space and long-term maintenance.
In short: nothing wrong with a distiller — it depends on the setting
A water distiller suits small, designated uses. But with its production time, higher power draw, flat taste and regular upkeep, it is rarely the most convenient daily option for a Hong Kong office or home. If you need steady supply for many people, hot and cold water, cartridge maintenance and long-term management, an RO dispenser or RO filter deserves the comparison.
Contact Bio-Link to arrange a drinking water consultation — the team will suggest the right RO, UF, countertop or freestanding option for your office, school, clinic or home.
