Abstract
Filter capsules for showers and sinks used in surgical settings, clean rooms and other contaminant-sensitive settings having modified outlets for improved splash control. Flat, concave, convex, asymmetric concave and asymmetric convex outlet inserts have pluralities of fluid bores with varying orientations to permit enhanced fluid flow control out of the filter capsules including divergent, convergent and mixed divergent/convergent fluid flows. An inlet with an axis offset at an angle to the longitudinal axis of the filter capsule body permits user control over the fluid flow strike point in a sink or shower stall via rotation of the capsule about the inlet connection point. A recessed outlet improves the prevention of contaminant dispersal by recessing the outlet away from contact points and potential contaminant sources. A filter cartridge top cap includes a downwardly extending extension with a concave bottom end to redirect fluids undesirably entering the filter capsule from the outlet away from the enclosed filter media and out the outlet.
