Abstract
A filter unit includes a substantially cylindrical body portion with a proximal end and a distal end. First and second engagement surfaces traverse at least a part of the body portion. The first and second engagement surfaces include a first segment that extends substantially parallel with a longitudinal extent of the body portion and a second segment that extends at an angle relative to the first segment. An engagement protrusion extends from the proximal end of the body portion and has a water inlet and a concave engagement wall with a water outlet. A periphery of the engagement wall includes a first portion with a first radius of curvature and a second portion with a second radius of curvature that is larger than the first radius of curvature. First and second seals are disposed about the engagement protrusion. The water inlet is disposed between the first and second seals.
