A crisper drawer for a refrigerator having a refrigerated compartment is disclosed. The crisper drawer includes a plurality of side walls defining a storage chamber, an opening in a side wall to provide fluid communication between the storage chamber and the refrigerated compartment, and a multi-function filter cassette configured to be positioned within the opening. The multi-function filter cassette includes a first filter configured to remove contaminants from a first air flow within the refrigerated compartment, a second filter configured to remove contaminants and/or moisture from a second air flow within the storage chamber, and a central wall configured to prevent fluid communication between the refrigerated compartment and the storage chamber.

In one aspect, a modular filter assembly for filtering fluid that flows in a flow direction therethrough is disclosed. The assembly includes a first housing section having a first filter element; a second housing section having a second filter element; and a connector disposed between the first and second housing sections. A housing includes the first housing section, the connector, and the second housing section. The flow direction is through the first and second filter elements in series.

A filtration system includes a filter housing and a filter cartridge. The filter housing includes a base and a cover removably coupled to the base. The cover includes a retainer. The filter cartridge has a longitudinal axis and is movable between an installed position within the filter housing and an uninstalled position outside the filter housing. The filter cartridge includes a top endplate including at least one protrusion extending upwardly away from the top endplate. The protrusion includes a tab extending radially outward from the protrusion that is structured to interact with the retainer to removably couple the filter cartridge to the cover. The filter cartridge further includes a bottom endplate and a filter media extending axially between the top endplate and the bottom endplate.

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.

A coalescence element is provided with at least one coalescence medium configured to coalesce water contained in a fluid. The at least one coalescence medium is made of a material with a packing density of at most 10%. The coalescence element is embodied as a single layer formed as a cylindrical jacket and has a fluid path for a fluid between an inlet side and an outlet side of the cylindrical jacket. A filter element with a filter bellows and a support pipe arranged coaxially inside the filter bellows is provided with such coalescence element that is arranged between the filter bellows and the support pipe in the flow direction so as to surround the support pipe at a radial outer side.

A customizable multi-stage fluid treatment assembly typically includes a connector, a plurality of cartridges, and a cap. The plurality of cartridges have a treatment medium spaced within an interior volume of the individual cartridges, between the ends thereof. The ends of the plurality of cartridges are configured to receive a fluid, bring the fluid into operative contact with the treatment medium, and dispense the fluid from the opposing end of the cartridge. The connector is coupled with one end of the plurality of cartridges and has an inlet and an outlet for receiving and dispensing the fluid to and from an appliance. The cap is coupled with the other end of the plurality of cartridges, enclosing the fluid treatment assembly, which is configured to be received in a cavity of an appliance. The cartridges of the plurality of cartridges may be individually replaced with cartridges to meet customized needs.
