A collar for use on a water filtration tank adapter. The collar is formed as a ring adapted to thread onto the tank connection end of the adapter and abut the nut portion between the tank connection end and the pipe end of adapter. An o-ring, square in cross-section, is disposed on a top surface of the collar, offset medially towards the center. This top o-ring is adapted to abut the nut portion of the adapter. Another o-ring, square in cross-section, is disposed on the bottom surface, offset medially away from the center. This bottom o-ring is adapted to abut the tank head upon use. Accordingly, a water-tight seal is formed at the tank connection end and tank head, the collar functioning as both a positive stop and as a substitute for pipe tape.

A water purification filter element is provided. The water purification filter element may include a filter bottle, a filter material, an end cover, and a water self-stopping and passing structure.

The instant disclosure seeks to provide a container lid that allows a liquid to be filtered, carried, and poured using the same lid. The container filter lid includes a lid body, filter material, and filter cap. The filter cap is demountably coupled the lid body. The filter cap includes a top surface. The filter material is positioned between the filter cap and the lid body. The lid body includes a first port. The filter cap includes a second port. The filter cap includes a filter reservoir. The filter reservoir extends from the filter cap opposite the top surface. The filter material is positioned adjacent to the filter reservoir. The filter reservoir is positioned between the top surface and the filter material. The lid body includes a pour spout. The pour spout is positioned opposite the first port. The container filter lid also includes a filter cap gasket.

A filter device for the filtration of fluids, at least consisting of a filter housing (10), which can be closed by means of a cover (40), and a filter element (30) accommodated in a replaceable manner in the filter housing (10), is characterized in that at least one functional element is present on the cover (40) and on the filter housing (10) and on the filter element (30) in such a way that the filtration of the fluid is only possible when all functional elements interact simultaneously.

A filtration system includes a housing and a filter element positioned within the housing. The housing includes a first housing end and a second housing end. A drain opening is defined in the second housing end. The filter element includes a first endplate and a second endplate defining an endplate opening. Filter media is positioned between and extending axially between the first endplate and the second endplate. The filter media defines a central opening extending axially therein. A drain plug axially protrudes from the second endplate in a direction away from the filter media. The drain plug is configured to engage the drain opening and facilitate installation of the filter element into the housing. A lid is configured to engage the first housing end. The engagement between the lid and the first housing end occurs when the drain plug is disposed within the drain opening.

A filter housing includes a container with a surrounding wall defining an open interior volume; the container having an access opening in communication with the interior volume;) a filter element in the interior volume; the filter element having an inlet face and outlet face and oriented for filtering gas by gas flow through the inlet face and out through the outlet face; a lid removably mounted on the container to cover the access opening; and a gas inlet and gas outlet in at least one of the container and lid; the gas inlet and gas outlet being co- planar. The gas inlet and the filter element are arranged such that inlet gas turns at least 90° to flow from the gas inlet to the inlet face of the filter element.

A filter element sensor module having a housing, a sidewall of the housing including a recessed portion. The sensor module including a sensor assembly being provided within the housing about a sensor port interface being provided at one end of the housing. The sensor module also including processing circuitry being configured to receive signals from the sensor assembly and communication module, the communication module being configured to transmit one or more sensed parameters from the sensor assembly.

An engine includes a filter housing with a base and a housing cover that contain a filter cartridge. The base defining a central recess, and having an annular sump extending downwardly from the central recess. An inwardly facing cylindrical sealing surface partially defining the annular sump, a drainage port defined in the cylindrical sealing surface and extending radially outward therefrom. The housing cover with a closed upper end and a downwardly extending annular wall sized to extend into the sump, the annular wall having a pair of seals that, when the housing cover is fully seated with the base provides a seal above the drainage port and a seal below the drainage port, the pair of seals precluding entry of oil into the drainage port when the housing cover is fully seated; whereby when the housing cover is raised upwardly, the lower seal is raised above the drainage port and oil in the filter housing drains out the drainage port.

Various example embodiments relate to a filtration system and methods for the installation and use of such a filtration system. According to a set of embodiments, the filtration system comprises a housing that defines a central compartment therein. The filtration system further comprises a filter cartridge positioned within the central compartment of the housing. The filter cartridge comprises a filter media and an identification element. The filtration system further comprises a sensor. The sensor is structured to sense the identification element of the filter cartridge. The filtration system further comprises a filter blocking mechanism communicably coupled to the sensor. The filter blocking mechanism is structured prevent installation of the filter cartridge into the housing unless filter cartridge information of the identification element sensed by the sensor is identified as corresponding to an authorized filter cartridge.

Provided are a water purifying apparatus and a refrigerator including the same. The water purifying apparatus includes a filter configured to purify incoming water and discharge the purified water, a head in which the filter is detachably coupled and a water inlet portion and a water outlet portion are formed, and a shaft provided inside the head and rotatably mounted between the water inlet portion and the water outlet portion, the shaft being provided with a bypass flow path directly connecting the water inlet portion and the water outlet portion and a filtering flow path connected so that water flowing in through the water inlet portion is discharged to the water outlet portion via the filter.
