Woman holding a glass beside a kitchen sink with a five-stage reverse osmosis system installed below

Designed for Australian mains water, the 5 Stage Reverse Osmosis system uses a sediment filter to catch suspended particles and two carbon stages to help reduce chlorine, unwanted tastes and odours. The reverse osmosis membrane reduces dissolved salts and selected substances. The storage tank holds filtered water until it passes through the final carbon filter and out of the dedicated tap.

Tap-water contaminants and particles

How it works

Product configuration

The storage tank holds filtered water between the membrane and the final carbon polishing stage.

5Carbon polish

Cold supply → three pre-filters → RO membrane → storage tank → final carbon polish → dedicated tap.

The membrane sends a separate concentrated water stream to the drain.

Stage 1

Sediment filtration

Catches suspended particles such as dirt and sand.

Stages 2–3

Carbon filtration

Two carbon stages help reduce chlorine, taste and odour before the membrane.

Stage 4

Reverse osmosis membrane

Reduces total dissolved solids and selected dissolved substances.

Stage 5

Final carbon polishing

Finishes the water for taste and odour before it reaches the dedicated tap.
