Abstract
A unitary water filter assembly and method for removing all microbiological and multiple types of chemical contaminants from water used in an appliance for human consumption are provided. The filter assembly includes a first filter stage fluidly coupled to receive influent water for filtering chemical contaminants therein. A second filter stage is fluidly coupled to the first filter stage for filtering microbiological organisms therein. The filter assembly allows removal of all microorganisms such as cysts, bacteria, bacterial spores and viruses, from the drinking water. The filter assembly may also be configured to remove chemicals, such as chlorine, including associated taste and odor with such chemicals, particulates, and metal contaminants from drinking water. The filter assembly may be further configured to remove volatile organic compounds (VOCs), and other organic and inorganic contaminants from drinking water.
