StageOne V3.0 + StageTwo bundle + LED UVC + RO Combo (July Pre-order)

This is a pre-order sale for the new StageOne version 3.0 for release in July. Sales so far have exceeded expectations - sorry for the delay!

The new V3.0 features a more compact frame (5cm lower, 5cm shorter) a new brushless pump with additional protection measures as well as more robust components.  Auxiliary priming pump option (not necessary for most users)

The StageOne V3.0 + StageTwo + LED UVC + 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 four systems work in sequence:

StageOne V3.0 – 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)

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.

• Running costs: £30–£40 per year
• Warranty: 2 years

Offgrid UV-C LED Module (additional post-tank sterilisation)

Flow-activated UV-C sterilisation for to place after StageTwo 8 year lifespan never change the bulb! It's a great addition for those who want even more protection.

The Offgrid Water UV-C LED Module adds a microbiological treatment stage for water that has already been filtered. As water flows through the unit, UV-C LED light at the precise wavelengths of 260–280nm neutralises bacteria and microorganisms that may still be present.

Unlike traditional mercury UV systems, this module is flow-activated - it only switches on when water moves through it. This reduces power use, extends LED lifespan, and makes it well suited to boats, campervans and off-grid setups running on 12V or 24V DC. A 220V AC adapter can also be used where mains power is available. You could use your pump power supply to power it.

Specification

• Suitable source water: pre-filtered, stored tank, rainwater, mains-fed
• Power: 24W, flow-activated
• Power supply: 12V / 24V DC or 220V AC adapter
• Dimensions: approx. 30cm length x width 30mm (excl. connectors)
• Connections: 1/2" BSP female with 12mm hose barb options
• Maximum pressure: 0.1–0.4 MPa (approx. 15–60 psi)
• Sterilisation: UV-C LED, 260–280nm
• UV dose: 101.5 mJ/cm²
• Maximum effective flow rate: 15 litres per minute (perfect for boats)
• Expected lifespan: up to 8 years - never change bulb
  
• Safety: Status light (green/red) to show bulb activity
• 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.

• 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. There is the option to get an additional booster pump that helps prime and improve flow (for use if you're parked up several metres from a water source, for instance)

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
  
• Extra UV - extra protection! 

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.
