WATER FILTER SYSTEM

Abstract:

A water filter unit includes a body portion, a first engagement surface that traverses at least part of the body portion, and a second engagement surface that traverses at least part of the body portion opposite the first engagement surface. An engagement protrusion extends from the body portion and has a water inlet and a water outlet. A curved engagement surface is disposed on the engagement protrusion proximate the water outlet. A first seal is disposed on the engagement protrusion. A first cross-section of the engagement protrusion, taken at the first seal and perpendicular to a longitudinal extent of the body portion, has only one axis of symmetry. A second seal is disposed on the engagement protrusion and is spaced apart from the first seal. The water inlet is positioned between the first and second seals.
