Whole-house protection from bacteria, sediment, and chemicals — no chlorine, no compromise.
This high-flow wall-mounted system combines dual Big Blue pre-filtration with a 48W hard glass UV chamber to deliver comprehensively treated water to every tap in the home. Engineered for both mains and rainwater supply, it eliminates 99.9% of bacteria and viruses — including E. coli and Salmonella — without adding any chemicals or altering the taste or odour of your water. Suitable for residential properties, outbuildings, and caravans with direct mains connection.
Dual Pre-Filtration — Heavy-Duty Sediment Capacity
Two oversized Big Blue filter housings work in sequence before water reaches the UV chamber, maximising contaminant capture and protecting the UV lamp from sediment fouling. The first stage PP sediment cartridge uses multi-density polypropylene construction to trap sand, silt, rust, clay, loose scale, and large particles — with graded density layering that extends cartridge life and minimises pressure drop. The second stage carbon block cartridge reduces chlorine, VOCs, colour, taste, odour, rust, and scale, delivering clean-tasting water to the UV stage.
48W Hard Glass UV Disinfection
The stainless steel UV chamber houses a 48W high-intensity hard glass UV lamp that inactivates bacteria and viruses on contact. No chemical by-products. No alteration to water chemistry. At maximum dosage (40 mJ/cm²) the system treats up to 75 litres per minute, rising to 132 Lpm at 16 mJ/cm² — more than sufficient for whole-house residential demand.
Smart Control Head with Countdown Timer
The powder-coated stainless steel control head features a viewing window so the lamp countdown timer and warning lights are visible at a glance without opening the unit. An audible and visible alarm alerts you when the UV lamp is due for replacement. The hinged lid provides easy access for lamp changes without disturbing pipework.
Oil-Filled Pressure Gauge
An oil-filled stainless steel pressure gauge is mounted to the front of the unit, displaying real-time system operating pressure and indicating when filters are approaching the end of their service life.
Fast Plug & Play Installation
Designed for straightforward installation by a qualified plumber. The 1" BSP (25 mm) connections are standard throughout the UK and Europe. The unit mounts directly to an exterior or interior wall — the powder-coated stainless steel housing is rated for outdoor installation.

Filter Replacement Schedule
Stage 1 PP Sediment (Big Blue): every 3–6 months depending on water quality. Stage 2 Carbon Block (Big Blue): every 6–12 months. UV Lamp: annually — output degrades before the lamp fails visibly, so replace on schedule regardless of appearance.
