A filter cartridge including catches for ejecting the filter cartridge from a filter housing as the filter cartridge and filter housing are removed from a filter base is provided. The catches are configured to engage corresponding catches of the filter base to limit axial motion of the filter cartridge as the filter cartridge and filter housing are threadedly removed from the filter base.

The present invention describes a disposable filter unit (1) intended for a system (10) allowing for purification and recycling of water or separation of water, said disposable filter unit (1) comprising an outer body (2), a top (3), a bottom (4), an inflow (5), an outflow (6) and a filter means (7) enclosed in the outer body (2), wherein the inflow (5) is positioned adjacent to the bottom (4) and the outflow (6) is positioned adjacent to the top (3), and wherein the inflow (5) and (10) outflow (6) are arranged to be fixated simultaneously into the system (10) and released simultaneously from the system (10) enabling a simple replacing of the disposable filter unit (1) for a user, and wherein the system (10) comprises a mechanical filter fixating/releasing unit (8).

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.

A filter assembly comprises a filter housing defining an internal volume, a filter element positioned within the internal volume, and a gasket retainer. An outer edge of the gasket retainer is coupled to a top end of the filter housing, and an inner rim thereof forms a gasket retainer ledge. The filter assembly further comprises a retainer loop comprising a retainer loop main body. A plurality of retainer arms extend axially from the retainer loop main body towards the gasket retainer. Each of the plurality of retainer arms comprise a retainer arm ledge extending radially towards the retainer loop main body and snap-fit to the gasket retainer ledge. A retainer loop sidewall extends from the main body away from the gasket retainer. An outer surface of the retainer loop sidewall defines a curvature. A sealing member is removably positioned around the outer surface of the retainer loop sidewall.
