Quick Answers
What’s the difference between the 5-stage and 4-stage RO system?
The 5-stage system includes a final remineralisation cartridge that adds back calcium and magnesium for improved taste and mineral balance. The 4-stage system skips this step, focusing purely on removal without adding minerals back in.
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)
Coconut Carbon Filters (2x): every 12 months (2x $69)
Membrane: Every 3–6 years – depending on water quality and usage ($149)

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.
