SKU N/A Category

The Unpumped Series are systems designed to work at UK mains pressure, granted this is at least 43 psi / 3 bar. If you have water pressure below this, we recommend a system from our Pumped Series. This variation is a private water supply and household designed reverse osmosis system that achieves pure drinking water through carbon post filtration and the choice of UV sterilisation.

Ultraviolet sterilisation is a well established process to rapidly disinfect water without the use of heat or chemical processes such as chlorination or ozonisation. UV does not add anything to water such as undesirable colours, tastes or odours and creates no by product.

The system is rated at 50 gallons per day and contains an option to include a final polishing stage by utilising ultraviolet sterilisation. A modern and far more advanced way to treat water than using harsh chemical processes such as chlorination and ozonisation. All RO systems can be purchased with customisable consumables. Some are designed to target specific contaminants, eg. Chloramine, and others are rated at increasing efficiencies depending on the quality of your source water, and how long you would like your filters to serve for.
