A filtering nozzle assembly or spray head including a lumen or duct for dispensing or spraying a pumped or pressurized liquid product or fluid from a valve, pump or actuator assembly drawing from a transportable container to generate a spray of fluid droplets, comprising; (a) an actuator body having a distally projecting sealing post having a post peripheral wall terminating at a distal or outer face, said actuator body including a fluid passage communicating with said lumen; (b) a cup-shaped filtered orifice defining member mounted in said actuator body having a peripheral wall extending proximally into a bore in said actuator body radially outwardly of said sealing post and having a distal radial wall comprising an inner face opposing said sealing post's distal or outer face to define a fluid channel including a chamber between said body's sealing post and said cup-shaped member's peripheral wall and distal wall; (c) said chamber being in fluid communication with said actuator body's fluid passage to define a fluid filter inlet so said pressurized fluid may enter said fluid channel's chamber and filtering region; (d) said cup-shaped member distal wall's inner face is configured to define within said chamber a plurality of proximally projecting filter posts (1240A-1240L, 1440A-1440L) with a first proximally projecting filter post and a second proximally projecting filter post, wherein said proximally projecting filter posts (1240A-1240L, 1440A-1440L) are radially arrayed and spaced apart to define inter-post filtering lumens (1250, 1450) therebetween for filtering passing pressurized fluid flowing through said chamber to provide a filtered fluid flow; and (e) wherein said chamber is in fluid communication with fluid oscillation inducing features (1220, 1222, 1224, 1420, 1422, 1424) and a discharge orifice defined in said cup-shaped member's distal wall (1280, 1480), wherein the fluid oscillation inducing features (1220, 1222, 1224, 1420, 1422, 1424) are two opposing venturi shaped power nozzles (1222, 1224, 1422, 1424) aimed at an interaction region (1220, 1420) and said filtered fluid flow exhausts from said discharge orifice (1230, 1430) as spray of fluid droplets in a selected spray pattern, wherein the cup shaped member is a one-piece, unitary fluidic cup oscillator configured with the plurality of integral proximally projecting filter posts (1240A-1240L, 1440A-1440L). (a) an actuator body having a distally projecting sealing post having a post peripheral wall terminating at a distal or outer face, said actuator body including a fluid passage communicating with said lumen; (b) a cup-shaped filtered orifice defining member mounted in said actuator body having a peripheral wall extending proximally into a bore in said actuator body radially outwardly of said sealing post and having a distal radial wall comprising an inner face opposing said sealing post's distal or outer face to define a fluid channel including a chamber between said body's sealing post and said cup-shaped member's peripheral wall and distal wall; (c) said chamber being in fluid communication with said actuator body's fluid passage to define a fluid filter inlet so said pressurized fluid may enter said fluid channel's chamber and filtering region; (d) said cup-shaped member distal wall's inner face is configured to define within said chamber a plurality of proximally projecting filter posts (1240A-1240L, 1440A-1440L) with a first proximally projecting filter post and a second proximally projecting filter post, wherein said proximally projecting filter posts (1240A-1240L, 1440A-1440L) are radially arrayed and spaced apart to define inter-post filtering lumens (1250, 1450) therebetween for filtering passing pressurized fluid flowing through said chamber to provide a filtered fluid flow; and (e) wherein said chamber is in fluid communication with fluid oscillation inducing features (1220, 1222, 1224, 1420, 1422, 1424) and a discharge orifice defined in said cup-shaped member's distal wall (1280, 1480), wherein the fluid oscillation inducing features (1220, 1222, 1224, 1420, 1422, 1424) are two opposing venturi shaped power nozzles (1222, 1224, 1422, 1424) aimed at an interaction region (1220, 1420) and said filtered fluid flow exhausts from said discharge orifice (1230, 1430) as spray of fluid droplets in a selected spray pattern, wherein the cup shaped member is a one-piece, unitary fluidic cup oscillator configured with the plurality of integral proximally projecting filter posts (1240A-1240L, 1440A-1440L).
