摘要

An apparatus for water filtration includes a base a filtration receptacle coupled to the base and a carafe removably coupled to the base. The filtration receptacle includes a water inlet and a water outlet. The filtration receptacle includes a pleated filter positioned between the water inlet and the water outlet. The pleated filter has a pleat face characterized by a surface having a plurality of peaks and a plurality of valleys, such that the surface is disposed in a plurality of planes. The filtration receptacle is structurally configured to maintain the pleated filter in an orientation wherein the pleat face of the pleated filter transverses a water-flow path extending from the water inlet to the water outlet. The filtration receptacle is further configured to induce water-flow along the water-flow path by at least one of a receptacle orientation and a receptacle geometry. The carafe includes an inlet coupled to the water outlet in the filtration receptacle.
