Abstract
Abstract In a preferred embodiment of the invention, a water-filter device is provided in which there are a plurality of insert filters into different compartments which insert filters are easily removed by unscrewing a bottom male portion from a top female portion, with the water being channeled to the respective filter compartments in parallel flow with one-another with the outlets of the several filter inserts being into the respective compartments and with the compartments being in flow series with one-another from a first compartment receiving water solely from the outlet of its insert filter to a final compartment of the series which has an outlet into a channel in flow communication with the main device water outlet, the compactness of filter material preferably of sheeps'' wool varying from compartment to compartment in the flow series of compartments, with the first compartment of the series having an insert of least insert filter material density and the last compartment of the series having an insert filter of filter material of the greatest density, filter material being also in the compartment of the flow series with the filter material being outside of the inserted filter, the filter material out of the inserted filters being of about the same density for each of the series of compartments, and there being additionally provided a valve mechanism for alternately passing water through the filters when the valve is in one position and through a bypass conduit bypassing the filters in their entirety when the valve is in an alternate position, the valve being preferably manually controllable, a good part of the utility of the present invention being the high efficiency of the fiber system together with the ease of access to and replacement of the insert filters.
