The invention provides filters and methods of assembling filters. In an exemplary embodiment, the filter includes a porous element, a compression element, and a housing. The compression element can be configured to receive the porous element, thereby forming an assembly. For example, the compression element can receive the porous element in a slip-fit relationship. The housing can have an opening formed therein that is configured to receive the assembly. In some embodiments, the assembly can be retained within the opening when the assembly is received therein. For example, the opening can receive the assembly in a press-fit relationship.

A water purifier according to an embodiment of the present invention may include a housing accommodating components for generating cold water and/or hot water; and a water chute which protrudes from a front surface of the housing, in which the water chute includes a water cock through which cold water or hot water flows; and a light emitting element which is mounted on the water cock to emit ultraviolet rays, in which the water cock includes a water inflow part which extends in a transverse direction and has a water inflow passage formed therein; and a water outflow part which extends in a direction intersecting the water inflow part at an end of the water inflow part and has a water outflow passage formed therein, in which the light emitting element is disposed on the upper side of the water outflow part, and in which the water outflow passage includes a sloping part having a shape in which a cross-sectional diameter thereof gradually decreases toward the lower end thereof.

A food cooker comprises: a water supplying part for supplying, as hot water or purified water, water supplied from the tap or a spring water container, according to the selection of a user, so as to supply the water such that food can be cooked; a cooking part enabling food to be cooked using the water supplied to a container, and provided in the downward direction of the water supplying part such that the user can be prevented from being burned by residual heat after the food is cooked; and a controller part provided at the water supplying part and the cooking part so as to enable a water supply, heating time and temperature to be controlled such that the food contained in the container is cooked, and thus the present invention can be provided regardless of location and can prevent the user from being burned by residual heat after the food is cooked.

A composite absorbent filter media having adsorption and/or absorption properties for the filtration of ester oils from a liquid includes a graphene and/or graphite composite mixed into a final emulsion, which is subsequently heat treated or cured, cooled, compressed, and dried. The resultant adsorption/absorption media is then disposed within a plug structure having an ingress and egress for liquids mixed with ester oils to pass through. Alternatively, the resultant adsorption/absorption media is disposed into a fabric and formed as a wall used to enclose oil-filled equipment. The media adsorbs/absorbs the ester oils from the liquid, while allowing the liquid to disperse and pass through.

Proposed is a water filter, including filter segments provided by dividing the filter into two or more sections composed of materials or densities that are same or different from each other, and a connection cap mounted between the filter segments, wherein the connection cap communicates with a filter flow path of an anterior filter segment, is closed to a filter flow path of a posterior filter segment, is provided with a closing part at a location between the anterior filter segment and a filter casing, and is provided with a connection cap flow path between the posterior filter segment and the filter casing, thereby allowing the water purified primarily by the anterior filter segment to be drained into the connection cap flow path and then to be discharged through the filter flow path of the posterior filter segment after being processed through a secondary water purification process.

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.

A filter to remove contaminants from potable water. The filter comprises a plurality of porous layers 15,16 forming a fluid path for the water to pass sequentially from the first layer 16 through the layers to the final layer. The first layer 16 is formed of a ceramic and/or sintered material and includes a virucide. Said first layer 16 is distinguishable from an adjacent second layer 15, wherein at least one of the first and second layers 16, 15 comprises a dye material.
