Compact reverse osmosis water filter, complete with 3 stage filtration. Provides water for drinking, aquariums, plant propagation and use in pharmaceuticals.

This reverse osmosis water filter, like all unpumped reverse osmosis units, does rely on you having a strong mains water pressure, please do not buy this item if you do not have a good water pressure. This unit operates best at input water pressures of between 30psi (2 Bar) & 60psi (4 Bar). We would suggest that this is not suitable for use with gravity fed unpumped cold water systems (where the water is stored in the loft). Normal UK water pressure should be from around 2 bar and above.

Please note that all gallon ratings are quoted by the factory in US gallons, in which 3.78 litres = 1 US gallon. There are a number of factors that affect the output of reverse osmosis water filters, input water pressure, TDS of input water, bacterial film on RO membranes (not changing prefilters often enough) and, most important particularly in winter months, water temperature.

          Filter Life

          Dependant upon usage of the unit, the first and second cartridge filters will need changing every 6 months, and the membrane filter requires changing at approximately 12 to 18 months. The need to change filters is dependant upon actual use and the quality of your water.
