A filter module for a water dispensing device according to the present disclosure includes a filter housing which has an inflow port and a discharge port, and a plurality of filters which includes a filtration member provided in the filter housing to purify water flowing therein through the inflow port and to supply purified water to the discharge port, and filtering raw water flowing therein from the outside into purified water, and the filter module includes a pre-filter through which raw water passes firstly and in which a first carbon block having a hollow shape is built-in, a hollow fiber membrane (UF membrane) filter through which water passes through the pre-filter passes secondly, a second carbon block having a hollow shape through which water passing through the hollow fiber membrane filter passes thirdly, and an electrostatic adsorption member through which water passing through the second carbon block passes fourthly.

The invention provides a filter device 10 for a breathing device, the filter device 10 comprising: a housing 12 with a wall 13 made from a paper material and defining a volume, two openings 14, 16 in the wall 13 that communicate with the volume and a filter mounting portion 18 configured for mounting a filter media in the volume between the openings 14, 16. The invention also comprises an adaptor to connect a filter device 10 to a breathing device, the adaptor also made from a paper material.

In general, the disclosed filter system can include a primarily metal body defining a plurality of channels in fluid communication with one or more filter assemblies. An inlet of the metal body can be connectable to an air compressor or similar fluid source. An outlet of the metal body can be connectable to a pneumatic tool, pneumatic equipment, or an air distribution system. The filter system can include one or more plugs that are constructed and arranged to fluidly seal selected portions of a main channel to form a fluid-tight pathway through the plurality of channels and the filter assemblies.

A modular filtration platform having at least one manifold head and at least one respective filter cartridge assembly. Each manifold head is connected to one another to establish a water flow in a series or parallel manner. Each filter cartridge assembly is releasably secured from rotation relative to the manifold head by a locking mechanism. An aperture on the filter cartridge assembly annular collar mates with a protruding resilient extension on either the manifold head or support bracket. Alternatively, an aperture on the filter cartridge assembly annular collar and an aperture on the manifold head annular collar mate with a protruding member from a locking ring extending through both apertures. An integrated sensor package may be integrated with the system for true managed water visible/audible indications and Wi-Fi interface to facilitate virtually instantaneous response times for filtration needs.

A water filtration system with replaceable active components. The water filtration system includes an outer housing, an inner filter canister, and a housing cap. The outer housing includes an inlet opening and an outlet opening. The housing cap includes a cap inlet opening. The inner filter canister filters water entering through the cap inlet opening. The outer housing retains and holds replaceable active filter components. The outer housing retains and holds the inner filter canister within the outer housing. The inner filter canister includes a connector for coupling to a connector on the underside of the housing cap. The housing cap engages with the inlet opening to secure the inner filter canister and the active filter components within the outer housing. Water exiting from the inner filter canister will be further filtered by the active filter components before exiting the outer housing via the outlet opening.
