Common Questions Answered
What's included?
This is a complete, ready-to-install kit. It includes the full set of filters, a water storage tank, a dedicated drinking water faucet, and all hoses and fittings. You also have the freedom to select the specific tank size and faucet style that perfectly matches your kitchen and your family’s needs.
What’s the difference between the 5-stage and 4-stage RO system?
The 5-stage system includes a remineralisation filter that adds essential minerals like calcium and magnesium for better taste and balance. The 4-stage system does not include this final stage.
What's the difference between this and the Compact version?
This system has an additional sediment pre-filter stage. This first step removes rust, sand, and other large particles, which helps protect the internal filters and can lead to a longer lifespan for your cartridges. The compact RO system does not come with a sediment pre-filter.
Can I use this RO system for tank and bore water?
This system is best suited for town (mains) water. Tank water sources often lack the strong pumps needed to provide the water pressure required for RO systems. For tank or bore water, please explore our Rain Water Tank Filter options that provide additional sediment and bacteria removal commonly found in untreated sources.
How often do I need to change the cartridges and how much do they cost?
Sediment Pre-Filter: Every 12 months ($69)
Carbon Filters (2x): every 12 months (2x $69)
Membrane: Every 3–6 years – depending on water quality and usage ($149)
Hydrogen-Rich Remineraliser: Every 12 months $119)

How does the Reverse Osmosis Membrane Work?
A reverse osmosis membrane is a thin film with tiny pores that permit only water molecules to pass through, blocking all contaminants. It’s made of a semi-permeable material that allows water flow but blocks dissolved salts, organics, bacteria, and pyrogens. When pressurised, pure water diffuses through the membrane into the permeate flow, leaving contaminants behind. Reverse osmosis removes up to 99% of impurities.
Polluted water is forced through the semi-permeable membrane by mains pressure. Pure water passes easily, while pollutants larger than.0005 microns are washed away into a waste stream that goes down the drain. This waste stream contains all of the filtered-out contaminants, including pesticides, metals, bacteria, and viruses. Reverse Osmosis systems are consistently one of the better PFAS water filters and water filters that filters fluoride as well.
