A collection funnel is positioned on a vehicle in order to collect rainwater and other moisture. Rainwater and other fluids from the collection funnel are directed to a conditioning cartridge where the water is de-ionized and windshield washer fluid is added. The cartridges are designed to be single replaceable units. The mixed fluid from the mixing cartridge is directed to the pre-existing windshield washer reservoir. ## Claims ### Claim 1 A vehicular windshield washer fluid replenishing system for conditioning and treating rainwater for use in a preexisting windshield washer reservoir comprising: a collection funnel having an angular shaped upper wall and lower wall spaced apart by opposing side walls, said collection funnel constructed and arranged for positioning between a windshield and hood of a vehicle, said collection funnel having an inlet available for receipt of rain water that drains from the windshield for directional passage through said collection funnel to an outlet; a housing defined by a top wall, a bottom wall, a pair of side walls, an inlet end wall, an outlet end wall, an intermediate wall extending horizontally between the top and bottom walls, and first and second passageway walls extending orthogonally from the bottom wall to the intermediate wall and from one of the sidewalls to the other sidewalls, wherein the first passageway wall is adjacent the inlet end wall and the second passageway wall is located adjacent the outlet end wall; an ion exchange resin chamber containing an ion exchange resin, wherein the ion exchange chamber is bounded by the first and second passageway walls, the intermediate wall, the bottom wall, and the pair of sidewalls; an inlet in a portion of the inlet wall adjacent the first passageway wall; a fluid conduit coupled to said inlet in said inlet end wall and to said outlet of said collection funnel for conditioning of collected rain water; a mixing chamber bounded by the outlet end wall, the second passageway wall, the intermediate wall, the bottom wall, and the pair of sidewalls, wherein said mixing chamber is fluidly coupled to said ion exchange chamber through said second passageway wall and adds a fluid concentrate to the conditioned rain water; a concentrate chamber containing said fluid concentrate, wherein the concentrate chamber is bounded by the top wall, the intermediate wall, and the inlet end wall, the outlet end wall, and the pair of sidewalls; a wick extending from the concentrate chamber to said mixing chamber for providing a capillary draw of said fluid concentrate from the concentrate chamber to said mixing chamber; an outlet in a portion of the outlet end wall adjacent the mixing chamber; and a fluid conduit coupled to said outlet in the outlet end wall, wherein said conditioned and treated rain water is directed to the preexisting windshield washer reservoir through said fluid conduit. ### Claim 2 (depends on 1) The vehicular windshield washer fluid replenishing system according to claim 1, wherein said ion exchange resin includes cation and anion mixed resins for reduction of total dissolved solids in the collected rain water. ### Claim 3 (depends on 1) The vehicular windshield washer fluid replenishing system according to claim 1, wherein said ion exchange resin is a cation exchange resin loaded with sodium ions for exchange of calcium ions in the collected rain water for sodium ions loaded on the cation exchange resin. ### Claim 4 (depends on 1) The vehicular windshield washer fluid replenishing system according to claim 1, wherein said first and second passageway walls prevent passage of ion exchange resin and provide an unrestricted flow of water there through. ### Claim 5 (depends on 1) The vehicular windshield washer fluid replenishing system according to claim 1, wherein the fluid conduit is releasably secured to the inlet in said inlet end wall with a quick connect coupling. ### Claim 6 (depends on 1) The vehicular windshield washer fluid replenishing system according to claim 1, wherein the fluid conduit is releasably secured the outlet of said outlet wall with a quick connect coupling. ### Claim 7 (depends on 1) The vehicular windshield washer fluid replenishing system according to claim 1, wherein said housing including said ion exchange resin chamber, said mixing chamber, and said concentrate chamber forms a single replaceable cartridge assembly. ### Claim 8 (depends on 7) The vehicular windshield washer fluid replenishing system according to claim 7, wherein said cartridge assembly can be reconditioned for reuse. ### Claim 9 (depends on 1) The vehicular windshield washer fluid replenishing system according to claim 1 including a sight glass in a portion of one of the sidewalls adjacent said concentrate chamber. ### Claim 10 (depends on 1) The vehicular windshield washer fluid replenishing system according to claim 1, wherein said collection funnel further including a mesh screen to filter out large particles.
