StageOne V2.1 + StageTwo bundle + RO Combo

Stock Limited – please allow approximately 1–2 weeks for delivery.

The StageOne V2.1 + 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 V2.1 – 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.)

• Version: V2.1 has upgraded plumbing and UV steriliser over the V2 unit

StageTwo – Polishing Filtration (Domestic-Use Water)

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

StageTwo Specification

• Source water: StageOne-purified water, stagnant tank water, or mains
• Power use: 0W (passive filtration)
• Dimensions: W35cm × D15cm × H35cm

• Flow rate: Up to 16 L/min
• Filter life: 4–8 months
• Running costs: £30–£40 per year
• Warranty: 2 years

FinalStage RO – Remineralised Drinking Water (Highest Purification Level)

The FinalStage Reverse Osmosis system delivers the highest purity drinking water available in a compact format. It removes chlorine, fluoride, nitrates, heavy metals, viruses, cysts, bacteria and hundreds of additional contaminants. The water is then remineralised for improved taste and health benefits (you do not need a separate remineralisation cartridge!)

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

FinalStage RO Specification

• Source water: Water purified by StageOne + StageTwo, stagnant tank water or mains
• Power: 230V (75W operating / 1.4W standby)
• 12V option: Yes 
• Dimensions: W14cm × D45cm × H40cm
• Weight: 10kg
• Flow rate: 1.6 L/min
• Filter life: 12–24 months
• Running costs: £70–£90 per year
• Warranty: 2 years

Variants

Canals and Rivers

Configured specifically for heavy-use boaters (narrowboats, widebeams, river cruisers). Includes filters optimised for high-sediment canal and river water.

Campers and RVs

Designed for overlanders and mobile users requiring more flexibility in filter choice and water sources.

Why Choose This Bundle?

• Full end-to-end purification from canal or river water to drinking water
• Integrated pump for easy water transfer
• Plug-and-play installation
• Weather-resistant construction
• Highest-quality remineralised RO drinking water
• Lower long-term filter running costs (filters readily available) 
• Ideal for boats, RVs, cabins, remote setups and off-grid homes
  

Please note that your standard water flow will slow depending on the pump that you have available as filters create resistance in water flow. A 25psi pump may not be enough - ideally you should have a 40psi or 3bar pump.
