The StageOne V2 + StageTwo + FinalStage RO Combo is our highest-spec complete purification package. Designed for boaters, off-grid cabins, RVs and remote installations, this system transforms water from canals, rivers, lakes or tanks into remineralised, drinking-water-quality water.

The three systems work in sequence:

StageOne V2 – Primary Filtration & Pumping (Source Water → Domestic-Use Water)

The Offgrid StageOne is engineered for challenging off-grid environments. It uses a seven-stage filtration process combined with LED UV sterilisation to treat water drawn from canals, rivers, lakes or rainwater. Durable, weather-resistant and fully self-contained, it efficiently removes sediments, contaminants, microorganisms and odour.

StageOne is fitted with an integrated pump, meaning there is no need for additional equipment—simply connect the hoses and begin filtering within minutes. The output water is suitable for washing, showering, general domestic use, or as a feed into the StageTwo unit for further purification toward potable standards.
(Please note: StageOne is not suitable for saltwater or brackish water.)

StageTwo – Polishing Filtration (Domestic-Use Water → Drinking-Quality Feed Water)

Installed after your pump or accumulator, the StageTwo unit further refines already-filtered water. Using de-ionisation, ultrafiltration and carbon filtration, it removes any remaining contaminants, microorganisms, tastes or odours.

A water-softening filter can also be integrated to protect appliances or improve shower quality.

FinalStage RO – Remineralised Drinking Water (Highest Purification Level)

The FinalStage Reverse Osmosis system delivers the highest purity drinking water available in a compact format.

This under-sink RO unit includes a dedicated drinking water tap.
