Abstract
An apparatus and corresponding method for purifying water is described. The apparatus includes a supporting housing, a source of power, a filter device containing at least one interchangeable filter unit having one or more filter elements, a mechanism for driving water through the filter device and a timing mechanism for monitoring elapsed time of operation and a mechanism for monitoring cumulative volume of water having flowed through the filter device which are each coupled to a filter memory. The mechanism for driving water through the filter device includes a cylinder holder on which an interchangeable gas pressure cylinder can be mounted, a gas release mechanism housed in the cylinder holder, a flow regulator and conduits connecting the other components together.
