How Much Can You Save with a 20-Litre Water Dispenser in Australia?
February 26, 20251 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.
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.

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.
