Suitably, a roller 122 is coupled to an axle of the pump and is adapted to contact with the driving wheel of the bicycle for driving the pump. The filter cartridge may comprise at least two chambers disposed between an inlet and outlet, wherein a first chamber (506, Fig. 5) comprises a first filter set, and a second chamber (508, Fig. 5) has a second filter. The second filter set can comprise activated carbon filters. A kit of parts for assembling a water filtration apparatus and a method of assembling the water filtration apparatus is also claimed. |
