A water purification tumbler includes a main body and a filtration unit. The filtration unit includes an annular wall, a flow conducting member, a high-temperature bamboo charcoal layer, and a low-temperature bamboo charcoal layer. The flow conducting member is disposed inside of the annular wall and defines a flow channel communicating with an opening of the main body. The flow channel has a water inlet section and a water outlet section. The water inlet section gradually narrows downward. The high-temperature bamboo charcoal layer and low-temperature bamboo charcoal layer are connected to the flow conducting member and are disposed respectively above and under the flow channel.

The technology disclosed herein relates to, in part, a filter assembly having a primary media assembly and a secondary media assembly in fluid communication with the primary media assembly. A filter assembly outlet is downstream of the secondary media assembly. A filtration pathway extends through the primary media assembly, the secondary media assembly, and the filter assembly outlet. A drain pathway extends through the secondary media assembly and the filter assembly outlet, wherein the drain pathway circumvents the primary media assembly.

A deaeration system is disclosed. A preliminary filtration stage is configured to filter particles from and nucleate gas in a fluid stream to create a filtered fluid stream. A primary filtration stage is downstream of the preliminary filtration stage configured to separate the filtered fluid stream into a first liquid stream and an air cavity concentrate stream. A secondary filtration stage is configured to receive the air cavity concentrate stream and separate the air cavity concentrate stream into a second liquid stream and a gas stream.

A hydronic system separator has an air separator with a vent release mechanism to remove air from the fluid within a hydronic system. The separator includes a magnetic assembly for collecting ferrous particles from the fluid. One or more screens are used to remove other particles from the fluid. The separator housing includes a removable debris collection receptacle that has a drain assembly.

A filter unit includes an inlet for receiving unfiltered water. A first fluid path directs water through a membrane and a filter element to a first outlet. Additionally, a second fluid path directs water across the membrane and to a second outlet.

A filter element, for use filtering liquids such as fuel, includes a first section of filter media, an optional layer of coalescer media, and a section of barrier media. The first section and optional coalescer filter media are held between opposite first and second end caps. The second end cap is integrated with the barrier filter media. The barrier media extends at least part way into an interior of the first section and can be conical in shape.
