How Much Can You Save with a 20-Litre Water Dispenser in Australia?

February 26, 2025 1 min read

Bottled water is expensive. A 20-litre water dispenser is one of the most cost-effective ways to provide filtered water for a household or office in Australia. Here’s a realistic cost comparison.

Browse our water cooler and dispenser range or see our Water Coolers Guide.


The Cost of Bottled Water

A 600ml bottle of water costs approximately $2.50–3.50 at retail. A household of 4 drinking 2 litres per person per day goes through approximately 13–14 bottles per day — around $35–50/week, or $1,800–2,600/year. Even buying 10-litre bulk packs from the supermarket costs significantly more per litre than a filtered water dispenser.

The Cost of a 20-Litre Water Dispenser

Our benchtop water coolers use a 20-litre bottle and an 8-stage KDF filter cartridge. The cartridge costs approximately $50–70 and lasts 6–12 months. The 20-litre bottle is reusable — refill from your tap and filter through the system. The cost per litre of filtered water is a fraction of a cent.

Realistic Annual Savings

Option Annual Cost (4 people)
600ml bottled water (retail) $1,800–2,600+
10L bulk supermarket water $400–800
20-litre water dispenser (AWF) ~$50–70 (cartridge only)

The system typically pays for itself within the first few months of use.


Frequently Asked Questions

Do I need to buy new 20-litre bottles or can I refill them?

Our benchtop water coolers are designed to be refilled from your tap — the 8-stage KDF cartridge filters the water as it passes through. You don’t need to buy pre-filled bottles. Browse our water cooler range.

How often do I replace the cartridge?
