A fluid filter comprising a housing having walls defining a cavity, a particulate filter medium contained in a first portion of the cavity, an ion exchange member contained in a second portion of the cavity, wherein the particulate filter medium and the ion exchange member at least partially define a parallel fluid pathway for fluid entering the housing cavity, wherein a first portion of the fluid pathway by-passes the particulate filter medium and passes through the ion exchange member without passing through any particulate filter medium in the housing, and wherein a second portion of the fluid pathway passes through the particulate filter medium.
