A water purifying apparatus for a refrigerator includes a head, a filter housing inserted into the head, a filtering member inside the filter housing, a head insertion portion inserted into the head and coupled to the head, and a fixing portion protruding along a circumference of the head insertion portion, and a sealing member fixed to the fixing portion and disposed along a circumference of the filter housing. The sealing member includes a sealing portion configured to protrude outward along the circumference of the filter housing so as to be in close contact with the inner surface of the head, a hook portion disposed below the fixing portion to be restricted by the fixing portion, and a connection portion configured to connect the sealing portion to the hook portion.

Described are liquid filter apparatuses that include a housing, an interior within the housing, a cartridge assembly (otherwise known as a filter cartridge) contained within the housing, and a vent that allows gaseous fluid from an interior of the housing to be released to an exterior of the housing, as well as related methods.

A supporting device for the separation of microplastics from an outdoor water source. This device separates into portable components able to be transported. This device comprises a structural system that can freely stand in the water source and provide an elevated surface to secure a micron filter above the surface of the outdoor water source. The water from the water source is manually collected and poured through the top of the device. The microplastics in the poured water are removed by the secured micron filter, and the water passes through the device to return to the outdoor water source by gravity. The source of separated microplastics is derived from plastic material so the device is comprised of all metal material so that additional microplastic sources are not introduced during use.

A water purifier includes: a filter module for providing purified water by filtering raw water; a fitting valve module detachably fastened to the filter module to provide at least one of a flow path for a flow of raw water supplied to the filter module and a flow path for a flow of the purified water discharged from the filter module; and a frame including a valve support for movably supporting the fitting valve module to be movable. The fitting valve module is selectively placed in a separated state in which the fitting valve module is separated from the filter module by moving in a direction away from the filter module, or a coupled state in which the fitting valve module coupled to the filter module by moving toward the filter module.
