A filtering system (10) includes a filtering apparatus having a filter unit for receiving liquid to be filtered, a receptacle for receiving filtered liquid, and an adapter (14) for coupling the filter unit to the receptacle, and also includes a base (12) having a cradle (26) for receiving the filtering apparatus and a base vacuum delivery port (28). The adapter includes an adapter vacuum receiving port (22) coupled to the vacuum delivery port for driving the liquid through the filter and—as filtered liquid—into the receptacle. The cradle and the adapter have an interlocking mechanism (52, 54) that locks the filtering apparatus to the cradle in a locking position in which the vacuum receiving port is sealingly coupled to the base vacuum delivery port. The base vacuum delivery port has a vacuum valve (30) constituted as a normally-closed valve automatically forced open when the filtering apparatus locks to the cradle.

Various example embodiments relate to a filtration system. The filtration system comprises a housing having a first housing end and a second housing end. The housing defines a central compartment therein. The housing comprises a key slot disposed on the first housing end and a housing key element protruding from the first housing end toward the second housing end. The filtration system further comprises a filter element positioned within the central compartment of the housing. The filter element has a first filter end and a second filter end. The filter element includes filter media and an endplate disposed on the first filter end. The endplate includes a central endplate opening, a key element configured for engagement with the key slot, and an installation guidance element formed along the central endplate opening. The installation guidance element is configured for engagement with the housing key element.

A water purifier includes a water purifier body, a filter bracket provided inside the water purifier body, a pump unit provided inside the water purifier body and including a pump connected to a main water purifying filter installed in the filter bracket, and a vibration transmission-preventing unit which, while the main water purifying filter is installed in the filter bracket, ensures the transmission, to the filter bracket and the water purifier body, of vibrations due to the pressure difference between the pump and the main water purifying filter when water is supplied to the main water purifying filter by means of the pump is reduced by a filter vibration-damping member.

An air management device for a filter assembly includes a top portion, a bottom portion, a plurality of frame members that connect the top portion to the bottom portion so as to define an inner cavity, and an air management valve. The air management valve includes a base portion, an intake valve, and an exhaust valve. The base portion is provided at the bottom portion. The intake valve extends into the inner cavity from the base portion towards the top portion. The intake valve includes an elongated opening that extends along a longitudinal length of the in-take valve. The exhaust valve extends into the inner cavity from the base portion towards the top portion. The intake valve is configured to intake air through the elongated opening and the amount of air introduced through the elongated opening varies based on a fluid level present within the air management device.
