A system disinfects air. The system includes an elongated chamber having an inlet configured for air to flow into the chamber. The chamber also has an outlet configured for air to flow out of the chamber, and a sidewall formed from a material that is at least 90% UVC reflective. The chamber defines a longitudinal axis. A LED is positioned to emit UVC radiation in a direction substantially perpendicular to the longitudinal axis of the chamber. A filter is configured to trap pathogens. The filter is formed of a material that is UVC reflective and UVC transmissive.

Removable and replaceable outlets for point-of-use showers or faucets, filter devices, and methods and systems including the outlets and/or filter devices, are disclosed.

The invention relates to a shower arm with a torus regulator and a magnetic ring that is comprised of a body (1) with a body head (25), a bell (2), a cover (3), a torus (4), a mixing element (5), a ring (6), a pin (7) and a barrier (9) on the cover, a barrier (8) and a nozzle (10) on the bell, a cavity (11) for water inlet, an inlet (12) of water into the shower head (25), a space (13), a gap (14) on the mixing element, a chamber (15), gaskets (16) and (17), a thread (18), a space (19) for directed flow, pins (20) and a groove (21) on the ring, a groove (22) on the bell, a thread (23) for connecting a hose, a support surface (24) a magnetic ring (26) and an output spray (27) of water and air. When the water circulates within the space (19) underneath the torus (4), negative pressure—vacuum occurs from both the internal and the external sides of the torus cross-section that conditions suction of the air from the chamber (15) of the cone of the bell (2). This air is suctioned through the nozzle (10). In the space below the mixing element (5) the air and the water swirl which alternately enter into the air/water mixture and form a wide conical spray (27). The bell is provided with the groove (22), into which the ring (6) with pins (20) is tightly inserted. The pins are made from a soft material and serve for mechanical massage of the skin and the crown of the hair. On the other side in the ring there is the groove (21), into which the magnetic ring (26) is inserted. Its role is to normalize the water crystals and to arrange them into a natural shape. The nozzle (10) for spray outlet has an orifice large enough in order not to clog due to impurities in the water and limescale.

A medical device includes: a hollow body part formed in a predetermined bent shape; a head part provided at a tip portion thereof with a discharge port for discharging cleaning water and detachably coupled to a front end of the body part; a connection part connected to a shower hose and a rear end of the body part and provided with a control valve for controlling water supply, a water flow rate and a water pressure; a water purification tube built in the body part and provided with leakage preventing grilles at both ends thereof; and a purified water discharge part provided inside the head part and configured to remove foreign substances in the water by using a filter.

A showerhead assembly including a filter cartridge assembly having a replaceable filter cartridge. The showerhead assembly includes a water-directing and filtering assembly having a body portion and a face portion removably affixed to the body portion. The filter cartridge assembly includes a split filter cartridge housing and filter cartridge. A first part of the filter cartridge housing is disposed in the body portion and a second part is disposed in the face portion. The filter cartridge includes a casing and spaced apart first and second end walls, an inlet connector extending axially from the first end wall, and an outlet connector extending axially from the second end wall and being offset from the filter cartridge central axis. The second end wall includes a first recess extending linearly between a peripheral edge of the second end wall and terminating at a termination position substantially aligned with the filter cartridge central axis.

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.

Bi-metal nanoadsorbents and methods for their preparation and use are provided. Methods of using bi-metal nanoadsorbents to remove contaminants from samples, such as water, are also provided.

A portable water conditioning system is provided that includes an incoming water inlet; a reverse osmosis stage in fluid communication with the incoming water inlet, the reverse osmosis stage having a permeate outlet and a concentrate outlet; a diversion device having a diversion valve, the diversion valve placing the concentrate outlet in fluid communication with a waste water outlet; a deionizing stage in fluid communication with a pure water outlet; a bypass valve configured to selectively place the permeate outlet in fluid communication with one or more of the waste water outlet, the deionizing stage, and the pure water outlet; and a controller configured to control the diversion device and the bypass valve to provide water at the pure water outlet of a desired condition.

Provided is a shower head with the one-touch detachable structure, which is installed in a bathroom or on a sink. The shower head allows women or the old and the infirm who have weak wrist power and grasping power to easily connect and disconnect a handle body of the shower head to and from a hose in one-touch since the hose connected to a faucet and the handle body of the shower head in a one-touch detachable manner. Moreover, the shower head allows women or the old and the infirm who have weak wrist power and grasping power to easily connect and disconnect the handle body to and from the head assembly in one-touch since the handle body and the head assembly are connected and disconnected in a one-touch detachable manner.

The embodiments described herein include an apparatus for adapting an existing water fountain having a water supply line and an existing bubbler assembly for dispensing water to a filtered water fountain. The system includes an adapter base in fluid communication with the water supply line, a housing assembly secured to the adapter base, and a bubbler head assembly secured to the housing assembly for dispensing water. A filter cartridge assembly is disposed within the housing assembly and is in fluid communication with the adapter base and the bubbler head assembly.
