1. A water filter assembly for filtering a liquid, comprising: an inlet conduit;an outlet conduit;a filter housing;a manifold mounted to the filter housing and coupled to the inlet and outlet conduits;a filter cartridge disposed within the filter housing and removably mounted to the manifold, the filter cartridge having a filter medium disposed therein, the filter medium for removing contaminants from the liquid;a radio frequency identification, RFID, tag positioned at an outer surface of the filter cartridge, wherein the RFID tag is configured to detect liquid leaking;a liquid collector mounted to the filter housing and positioned below the filter cartridge, the liquid collector defining a collection volume, a side wall of the liquid collector extending around the collection volume of the liquid collector, the filter cartridge disposed above the side wall of the liquid collector, the RFID tag positioned above the collection volume of the liquid collector on the filter cartridge such that the RFID tag is remotely located from the collection volume of the liquid collector;an absorbent material extending longitudinally between the RFID tag and the collection volume of the liquid collector, the absorbent material configured for transferring liquid from the collection volume of the liquid collector to the RFID tag; anda water impermeable material positioned over the RFID tag and the absorbent material on the filter cartridge, the water impermeable material mounted to the outer surface of the filter cartridge such that the water impermeable material overlays the RFID tag and the absorbent material on the outer surface of the filter cartridge and such that the RFID tag and the absorbent material are encased between the water impermeable material and the outer surface of the filter cartridge, the water impermeable material positioned between the collection volume of the liquid collector and the absorbent material, the water impermeable material defining a passage extending through the water impermeable material to the absorbent material at the collection volume of the liquid collector, the passage configured for directing liquid from the collection volume of the liquid collector through the water impermeable material to the absorbent material, the water impermeable material covering the absorbent material on the filter cartridge such that the water impermeable material prevents the absorbent material from absorbing liquid leaking from the filter cartridge at locations other than the passage of the water impermeable material. 2. The water filter assembly of claim 1, wherein the filter housing and the liquid collector are constructed with continuous molded plastic. 3. The water filter assembly of claim 1, wherein the liquid collector is positioned for collecting liquid leaking from the filter cartridge. 4. The water filter assembly of claim 1, wherein the liquid collector is positioned below a connection between the filter cartridge and the manifold. 5. The water filter assembly of claim 4, wherein the liquid collector is positioned for collecting liquid leaking from the connection between the filter cartridge and the manifold. 6. A water filter assembly for filtering a liquid, comprising: a filter housing extending between a top portion and a bottom portion, the filter housing having a liquid collector positioned at the bottom portion of the filter housing, the liquid collector defining a collection volume, a side wall of the liquid collector extending around the collection volume of the liquid collector;a manifold;a filter cartridge coupled to the manifold, the filter cartridge having a filter medium disposed therein, the filer medium for removing contaminants from the liquid, the filter cartridge positioned above the side wall of the liquid collector;a radio frequency identification, RFID, tag positioned at an outer surface of the filter cartridge, the RFID tag positioned above the collection volume of the liquid collector on the filter cartridge such that the RFID tag is remotely located from the collection volume of the liquid collector, wherein the RFID tag is configured to detect liquid leaking;an absorbent material extending longitudinally between the RFID tag and the collection volume of the liquid collector, the absorbent material configured for transferring liquid from the collection volume of the liquid collector to the RFID tag; anda water impermeable material positioned over the RFID tag and the absorbent material on the filter cartridge, the water impermeable material mounted to the outer surface of the filter cartridge such that the water impermeable material overlays the RFID tag and the absorbent material on the outer surface of the filter cartridge and such that the RFID tag and the absorbent material are encased between the water impermeable material and the outer surface of the filter cartridge, the water impermeable material positioned between the collection volume of the liquid collector and the absorbent material, the water impermeable material defining a passage extending through the water impermeable material to the absorbent material at the collection volume of the liquid collector, the passage configured for directing liquid from the collection volume of the liquid collector through the water impermeable material to the absorbent material, the water impermeable material covering the absorbent material on the filter cartridge such that the water impermeable material prevents the absorbent material from absorbing liquid leaking from the filter cartridge at locations other than the passage of the water impermeable material. 7. The water filter assembly of claim 6, wherein side wall of the liquid collector and the filter housing comprise continuous molded plastic. 8. The water filter assembly of claim 6, wherein the liquid collector is positioned for collecting liquid leaking from the filter cartridge. 9. The water filter assembly of claim 6, wherein the liquid collector is positioned below a connection between the filter cartridge and the manifold. 10. The water filter assembly of claim 9, wherein a portion of the liquid collector is positioned directly below the connection between the filter cartridge and the manifold. 11. The water filter assembly of claim 1, wherein the water impermeable material comprises a plastic film adhered to the outer surface of the filter cartridge and the absorbent material comprises an electrolyte doped paper. 12. The water filter assembly of claim 6, wherein the water impermeable material comprises a plastic film adhered to the outer surface of the filter cartridge and the absorbent material comprises an electrolyte doped paper.
