  • Patent number: 10183869
    Abstract: A filtering system intended to be attached to the water tap in a shower. The system preferably uses two distinct filtering media in order to filter water—charcoal and kinetic degradation fluxion (“KDF”) media. The present invention preferably includes a bypass valve which allows the user to properly gauge and adjust the temperature of the water prior to passing the water through the filter. The present invention preferably includes two check valves as well. One such check valve is located at the filter entrance, and the other check valve is located at the filter exit. While the shower is activated, the pressure from the water forces each valve open. However, when the shower is not activated, each valve automatically closes (the valves are normally closed valves). The check valve system allows the KDF media to remain in a saturated state, which increases the efficacy and lifespan of the filtering media.

  • Patent number: 10022655
    Abstract: A filter cartridge having an endplate formed of polyurethane having a varying hardness is described. A first portion of the endplate is harder than a second portion of the endplate. The first portion of the endplate helps support the filter media of the filter element and maintain the shape of the filter element. The second, softer portion creates a seal between the filter element and a filter housing when the filter element is installed in the filter housing. The first portion and separate portions may be formed from different types of polyurethane or from the same type of polyurethane having a varying composition as a function of the radial distance of the endplate.

  • Patent number: 9999848
    Abstract: A dual bag filter is provided where a replaceable filter element resides in and is sealed to a filter housing. The filter element has a mounting ring, an inner bag, and an outer bag. The inner bag is sized such that it has more surface area than the outer bag and is constrained by the outer bag. The inner bag is formed from a filter medium of different densities such that when the inner bag is crumpled, fluid flow is not restricted.

  • Patent number: 9993756
    Abstract: The invention relates to a filter (10) having at least a first bayonet joint (22). The first bayonet joint (22) has a first bayonet slotted guide (26) with two locking positions that are axially spaced apart from one another for a first bayonet projection (24) of the first bayonet joint (22). By rotating a filter part for releasing the first bayonet joint (22), the first bayonet projection (24) may be moved from the second locking position into the first locking position. The filter (10) preferably has a second bayonet joint (28). The second bayonet joint (28) is preferably embodied such that, by further rotation in the same direction of rotation, it is released in that a second bayonet projection (30) is moved out of a third locking position of a second bayonet slotted guide (32) of the second bayonet joint (28) after the first bayonet projection (24) has been stopped in the first locking position.
