"Buy the system, not the bottle". Even the smallest entry-level H2O water purifier provides 11 000 litres of excellent purified water. Each system saves the environment from the impact of 22 000 small bottles of "carbon hungry" plastic bottles! Take a re-usable environment friendly container to an H2O Filling Station and draw your own excellent water at approximately 1 rand per litre. H2O systems are made of fully recyclable components, but it is their use, in the place of buying small plastic bottles of water, that really saves the environment.
