How to Make Sparkling Water at Home in Singapore

The simplest way to make sparkling water at home is to chill plain water and carbonate it in a purpose-built machine. In Singapore, the practical choices are a countertop carbonator such as SodaStream or Drinkmate, a soda siphon with individual chargers, or an all-in-one water dispenser with built-in carbonation.

The methods differ far more in upfront price and workflow than in the bubbles they produce. Start with how often you will use it, what else the appliance needs to do, and how you will exchange CO2.

Method 1: Countertop Carbonator

This is the best starting point for most homes. You fill the manufacturer's bottle to its marked line with cold water, attach it, and use the button or lever to inject CO2.

The current SodaStream Singapore range includes the Terra, Art, and electric E-Terra. When checked on 14 July 2026, prices ran from $219.90 to $369.90. The Terra and Art are manual; the E-Terra uses powered fizz presets.

Drinkmate Singapore also sells the OmniFizz. Its removable infuser is designed to carbonate drinks beyond plain water. That flexibility also means the infuser and bottle need thorough cleaning after sugary drinks.

Basic steps

1. Chill plain water. Cold water generally retains CO2 better.
2. Fill only to the bottle's marked line.
3. Attach the bottle exactly as the manual shows.
4. Carbonate using the recommended number of presses or preset.
5. Release pressure as directed before removing the bottle.
6. Add flavour afterwards unless the machine explicitly permits other liquids.

Advantages

• Lowest practical upfront cost.
• Manual models need no power or plumbing.
• Easy to move between homes.
• Adjustable carbonation.

Trade-offs

• One bottle is prepared at a time.
• The machine and bottle take counter and storage space.
• It does not filter or change the water before carbonation.
• Bottles and cylinders are model-specific consumables.

Method 2: Soda Siphon

A soda siphon is a pressure-rated bottle with a dispensing lever. You fill it with cold water and use a small CO2 charger, commonly 8g, according to the siphon's manual.

This format is compact and familiar in cocktail preparation, but each charger typically handles one batch. Local price, availability of compatible food-grade chargers and the recycling route for spent chargers all affect ongoing use.

Never improvise with an unapproved cartridge or container. Inspect the siphon's seal and body, stay within the fill line, and release or open it only as the manufacturer directs.

Method 3: All-in-One Purifier and Carbonator

Velta HydroSpark+ combines a countertop RO purifier, temperature-controlled dispenser, and carbonator. It dispenses ambient, hot, chilled, or sparkling water and can use either a removable 5L source-water tank or a pipe-in connection.

It is not an under-sink system. The machine measures 220 × 508 × 436 mm and weighs 21.7 kg, which makes counter depth, overhead clearance, ventilation and a suitable power outlet part of the placement decision.

HydroSpark+ costs S$2,988. That is far more than a standalone carbonator, and its recurring items include a composite filter cartridge, CO2, and electricity. It only makes economic sense to compare if you also want its purification, heating, and chilling functions.

Advantages

• Ambient, hot, chilled, and sparkling output from one appliance.
• RO filtration before dispensing.
• Tank mode or pipe-in water supply.
• No bottle has to be attached to the nozzle for each glass.

Trade-offs

• Much higher purchase price.
• Large, powered countertop appliance.
• Filter and CO2 replacements add recurring cost.
• More maintenance than a manual carbonator.

Which CO2 Cylinder Do You Need?

CO2 connectors are not universal. Current SodaStream Terra, Art, and E-Terra models use the pink Quick Connect cylinder. Many older or third-party carbonators use a standard screw-in format. HydroSpark+ has its own supply arrangement.

Before purchasing, confirm:

• The exact connector used by the model.
• Whether a cylinder is included.
• Exchange price and locations in Singapore.
• Whether delivery, deposit, or empty-cylinder return conditions apply.
• The stated maximum yield and how carbonation strength affects it.

SodaStream's Singapore CO2 page listed a $29.50 exchange price and up to 60 litres when checked. The litre figure is a maximum rather than a guaranteed yield.

What Does Homemade Sparkling Water Cost?

Actual household drinking volume produces a more useful estimate than a generic “cost per litre” claim. The basic calculation is:

CO2 cost per litre = exchange price ÷ actual litres from your cylinder

At SodaStream's $29.50 exchange price and stated maximum 60L yield, the best-case CO2 cost is about $0.49 per litre. Stronger fizz lowers yield. Then add any flavour, filter, electricity, bottle replacement, delivery, and the upfront machine cost spread over the years you expect to keep it.

For HydroSpark+, total ownership cost includes the current filter price and interval alongside every other recurring item. A low per-litre figure based on unknown usage would not provide a meaningful comparison.

Can You Carbonate Singapore Tap Water?

Yes. PUB says Singapore tap water is suitable for drinking directly without further filtration. Chill it before carbonating. If you prefer filtered water for taste, filter it first or use a machine that filters before carbonation.

A purifier is not required to make ordinary Singapore tap water safe. If water is persistently discoloured or unusual, report and investigate the cause instead of assuming carbonation or filtration solves it.

Safety Rules

• Use only bottles, cylinders, chargers, and seals approved for the exact machine.
• Do not carbonate in an ordinary sealed bottle.
• Do not exceed fill lines or pressure instructions.
• Replace carbonating bottles by their printed expiry date or sooner if damaged.
• Keep cylinders secured, away from heat, and handled according to the supplier's instructions.
• Carbonate only permitted liquids. SodaStream specifies plain water; Drinkmate is designed for a wider range using its infuser.
• Do not use dry ice in a sealed household container. Expanding CO2 can create dangerous pressure.

Frequently Asked Questions

Is a sparkling-water maker worth it? It can be if you will use it regularly and have a convenient cylinder exchange. Compare your actual bottled-water spend with the machine, CO2, and consumables rather than relying on a universal payback claim.

How do I get stronger carbonation? Start with very cold water, stay within the fill line, and follow the machine's stronger-fizz instructions. More CO2 reduces cylinder yield.

Can I carbonate juice or cocktails? Only if the product explicitly supports it. Drinkmate's infuser is designed for other drinks. SodaStream directs users to carbonate plain water and add flavour afterwards.

How long will the water stay fizzy? It depends on temperature, carbonation level, container seal, headspace, and how often it is opened. Keep it cold and tightly sealed.

What is best for a small HDB kitchen? Measure first. A manual carbonator has a smaller footprint and needs no plumbing, while an all-in-one dispenser saves having several separate appliances but is much deeper and heavier.
