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 point of use reverse osmosis system, ideal for household and commercial use when high volumes of refined water are required quickly. They will improve both the aesthetics of the water as well as removing any bad tastes or odours.
Larger than our slim range of systems, the RO-300 utilises a third stage of pre filtration in the form of granular activated carbon. Compared with only the two stages in our slim systems, this both prolongs the life of the RO membrane inside and also work more effectively to reduce chlorine levels within your water. 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.
