HydroSpark+ versus bottled sparkling water: the real cost per litre
An honest sparkling-water-machine calculation includes the HydroSpark+ appliance, annual filtration and CO2—not just the gas in each glass. Here is the one-, three- and five-year cost at one litre of sparkling water a day.

What bottled sparkling water costs in Singapore
Shelf prices move, so treat these as rounded working figures checked in August 2026. The product names do not matter to the calculation; the cost per litre does.
| Bottled category | Typical unit price | Cost per litre |
|---|---|---|
| Premium sparkling, 330 ml | ~S$1.80 | ~S$5.50 |
| Premium sparkling, 750 ml | ~S$3.10 | ~S$4.10 |
| Mid-shelf sparkling, 1 L | ~S$2.50 | ~S$2.50 |
| House-brand sparkling, 500 ml–1.5 L | S$0.75–1.60 | ~S$0.75–1.50 |
Buy a named bottle or can instead of a generic category? Use the seven-brand FairPrice table and bottled-water spend calculator. It normalizes unlike pack sizes to price per litre and keeps refundable container deposits separate.
At one litre a day, S$4.10/L is a S$1,497 annual habit. Even the S$1.50/L house-brand assumption totals S$548 a year before delivery, storage or recycling.
The HydroSpark+ assumptions
Every input is shown so you can substitute your own consumption or confirmed consumable pricing.
| HydroSpark+ input | Value used | How it enters the model |
|---|---|---|
| Appliance | S$2,988 | Paid once at the start |
| 4-in-1 RO filter | S$168 / year | Listed price; confirm before purchase |
| CO2 exchange | S$26 / cylinder | Costed at 33 L: the HydroSpark+ manufacturer estimate of up to 100 × 330 ml servings. Confirm current price; actual yield can be lower. See the cylinder and replacement guide. |
| Sparkling consumption | 1 L / day | 365 L each year |
| Annual filter + CO2 | ~S$456 | S$168 filter + ~S$288 CO2 |
One, three and five years
These are cumulative totals, not instalment prices. HydroSpark+ is charged the full S$2,988 upfront plus S$456 for each year of stated filter and CO2 use.
| Option | Year 1 | Year 3 | Year 5 | 5-year cost / litre |
|---|---|---|---|---|
| Premium bottled sparkling water | S$1,497 | S$4,490 | S$7,483 | S$4.10 |
| House-brand bottled sparkling water | S$548 | S$1,643 | S$2,738 | S$1.50 |
| HydroSpark+ | S$3,444 | S$4,356 | S$5,268 | S$2.89 |
How to read the crossover
Against S$4.10/L bottled sparkling water, HydroSpark+ crosses below the cumulative bottle spend after roughly 35 months. Against S$1.50/L house-brand bottles, the crossover is roughly 33 years under these assumptions. Consumption changes both: a two-litre-a-day household reaches the bottle crossover sooner, while occasional sparkling use pushes it further away.
What this deliberately does not value
The model treats HydroSpark+ as a sparkling-water machine and charges its full purchase price against the bubbles it makes. Four-stage RO filtration and chilling count because they prepare the water for a better-tasting sparkling glass. Cold, ambient and hot still-water modes receive no financial value here; they are useful extras.
The bottom line
HydroSpark+ can undercut a premium bottled sparkling-water habit over its first three years, but inexpensive bottled water remains cheaper on sparkling output alone. The purchase case is fresh fizz on demand, filtered water for a cleaner taste and fewer bottles to store or replace. See how the sparkling-water machine works in the HydroSpark+ explainer.
