Our all new RODI+™ water purifiers deliver significant advantages to traditional reverse osmosis systems. Compact and quiet, they are the most water-efficient and advanced systems in their class, guaranteeing exceptional water quality and lifelong value.

Made in England, RODI+™ reverse osmosis systems use 75% less water and 97% less power than imported models and have a much lower carbon footprint. RODI+™ delivers a higher pressure and faster flow to the tap, some 33% greater than other systems on the market.

All RODI+™ reverse osmosis systems benefit from ROIntelligence™, programmed for efficient production with membrane protection, integrated leak detection and auto isolation. The membrane automatically flushes once a week, a process developed by Dr T Cummings, one of the world’s foremost water treatment design engineers, maintaining your system in peak performance at all times.

RODI+™ reverse osmosis systems use a unique four stage process. Water passes through a granular activate carbon stage, followed by reverse osmosis, de-ionisation, and finally carbon, removing 99.9% of all organic and inorganic contaminants from tap water, providing you with the healthiest and best tasting water. If you would like to learn more about the harmful contaminants found in tap water, please read these articles:

Compact in design RODI+™ can slide in the kick space below your cabinets and a range of storage tanks from 4 litres up to 200 litres can be connected to suit any busy environment.

All RODI+™ reverse osmosis systems come with our standard faucet. For the ultimate experience, we recommend installing with a quatreau® tap, providing you with the purest Boiling, Chilled and Sparkling water at the touch of a button. 

RODI+™ reverse osmosis systems can be installed in combination with a variety of water tanks and taps.
  • Purity Beyond Bottled Water – Using a four stage process, RODI+™ reverse osmosis systems remove 99.9% of all organic and inorganic contaminants.
  • Health – RODI+™ purifiers remove all harmful chemicals, micro-organisms, heavy metals, chemical compounds, pesticides, herbicides and drug residues from drinking water, delivering the most amazing purity and taste – on tap in your home, 24/7.
  • ROIntelligence™ – efficient production, integrated leak detection and auto isolation provide peace peace of mind. 
  • The Most Water-Efficient Reverse Osmosis System – They are 90% more water efficient and 98% more energy-efficient than purifiers imported from Asia or the USA.
  • Lower Service Costs – Fully automatic membrane flushing occurs once a week, maintaining the condition of your system and reducing the need for servicing. Developed by Dr T Cummings, flushing occurs during water production, reducing waste water.
  • Designed and Manufactured in the UK – With 90% of components manufactured within 5 miles of our offices, RODI+™ is sustainable and of the highest quality.

All RODI+™ reverse osmosis systems can be installed underneath your kitchen sink or in a remote utility room. Because they produce and deliver water at a constant 50 psi pressure they will happily feed devices throughout the kitchen such as boiling taps, coffee machines, fridges, ice makers and steam ovens.
