The present invention provides a water shower filter unit to provide clean treated water substantially free from chlorine, organic contaminants, and suspended solids by the use of primary filter, secondary filter and tertiary filter. The primary filter constructed from polymer material capable of filtering particle of 10 microns and above for eliminating suspended solid. The primary filter further comprises of chlorine removal material for removal of chlorine and contaminants. The secondary filter made of multiple layers of activated balls. Tertiary filter made of magnetic energy ceramics balls and mineral stones reside in elongated, hollow internal chamber of shower head is for water activation.

Disclosed are an integrated composite filter cartridge (200) and a water purifying system (300) having same. The integrated composite filter cartridge (200) comprises: an outer shell (20), wherein a chamber (21) is defined in the outer shell (20), and the outer shell (20) is provided with a raw water inlet (22), a pre-treated water outlet (23), a pre-treated water inlet (24), a purified water outlet (25) and a waste water outlet (26) which are in communication with the chamber (21); a pre-treatment filter cartridge (100); a central pipe (30); a filter membrane (40); and a control member, which is connected to the pre-treated water outlet (23) and the pre-treated water inlet (24). When the integrated composite filter cartridge (200) is used for the first time, the control member switches on the raw water inlet (22) and the pre-treated water outlet (23) and switches off the pre-treated water inlet (24).

A filtration module is provided, the module including at least one filtration packet containing filtration media or one or more membranes, such as a stack of membranes, the at least one filtration packet having one or more fluid ports, the one or more fluid ports being surrounded by a primary seal and a secondary seal spaced from the primary seal. The secondary seals are designed to maintain sterility of the assembly during shipping, handling and/or installation. A removable film may cover one or more fluid ports to maintain sterility prior to use.

A disposable filter capsule for a filtration device including only one housing, which has an inflow connection for a fluid to be filtered and an outflow connection for filtrate. The disposable filter capsule also includes at least two separate filters which are fixed in the housing and together with the housing form an inseparable structural unit. All the components of the disposable filter capsule consist of sterilizable, in particular gamma-sterilizable, materials.

A filtration system includes a filter housing having a cavity and a base, a drain defined in the base, a channel defined in the base and in fluid communication with the drain, and a filter cartridge having a longitudinal axis and being movable between an installed position within the cavity of the filter housing and an uninstalled position outside the cavity of the filter housing. The channel defines an outer diameter. The filter cartridge includes a bottom endplate defining an outer diameter that is greater than the outer diameter of the channel so that, in the installed position, the bottom endplate covers the channel and prevents fluid flow from the cavity to the drain, and a filter media extending axially outwardly from the bottom endplate.

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.

A back panel assembly for an aquarium has a housing with a dependent lip having connecting structure permitting the housing to be removably attached to an aquarium; and a cartridge holder removably positioned in the housing. The cartridge holder holds filter cartridges, each cartridge being the same size.

The disclosure pertains to a spin-on fluid treatment device, including a treatment medium disposed within a housing, a top surface having an internally threaded bore and an outlet tube at least partially disposed inside said threaded bore in a concentric position. The outlet tube can have an externally oriented sealing portion for engaging with a complementary element of an inlet spud of an entity that receives said treated fluids. The outlet tube can be configured as an alignment feature to guide the treatment device onto the inlet spud during installation. The outlet tube can be configured with both an externally oriented sealing portion and an alignment feature. The disclosure also pertains to a system comprising a machine having a treatment device head and a spin-on fluid treatment device, a kit, a spin-on fluid filter cartridge, and a method of mounting a spin-on filter cartridge onto a filter head.

A fluid-filtering apparatus includes an upper cartridge and a lower cartridge. The upper cartridge includes a permeable fluid-filtering first tube that surrounds and extends along an axis and that defines a first-tube cavity. An axially-extending permeable fluid-filtering second tube is located within the first-tube cavity and defines a second-tube cavity. The lower cartridge includes an axially-extending impermeable third tube that defines a third cavity. An axially-extending permeable fluid-filtering fourth tube, of the lower cartridge, is located within the third cavity and defines a fourth-tube cavity. The upper and lower cartridges are coupled together and contained within an impermeable casing.

A closed loop system for and method of capture, recycling, and safe disposal of microplastics, applied to residential and commercial textile washing and drying machine devices is proposed. The closed loop system allows for effective capture, processing and recycling, or safe disposal of microplastic material. The system employs an easy-to-use filter design, optimized to capture microplastics within the device or through air or water discharge lines, followed by post-processing of filter devices where the captured microplastic residue is physically or chemically processed for either recycling the captured microplastic residue into new filters or new products, or alternatively the captured microplastic residue can be locked into a safe matrix for disposal, wherein leaching from landfills into the environment is minimized or eliminated.
