The invention relates to filter-as-you-pour water filtration container systems. Such a system may include a container body, an outlet through which water within the container body may be poured and simultaneously filtered, a lid that may be releasably attachable over the container body, and a filter assembly attachable to at least one of the lid or the container body. The filter assembly may be disposed so as to be in a flow stream of the water, as the water is poured out of the container body through an outlet of the system, so that the stream of water exiting through the outlet is simultaneously filtered as it is poured from the container body. The system may further include a flow control device (e.g., a valve, grating, screen, etc.) disposed proximate (e.g., in or over) the outlet to regulate an exit flow rate of water being poured through the outlet.

In one example, a fluid container includes a reservoir that includes a reservoir wall. A cover is configured to engage the reservoir, and the cover includes a spout configured and arranged for fluid communication with the reservoir, and the spout is disposed at one end of the cover. The fluid container also includes a filter cage configured to releasably engage the cover in a location near the spout. When the filter cage is engaged with the cover, and the cover is disposed on the reservoir, a small gap is defined between the front of the spout and the front of the filter cage.

A storage container includes an input portion for receiving and filtering a source liquid to form an output liquid, a storage portion for storing the filtered liquid, and a base portion disposed below the storage portion including a UV light source for providing transmitted UV light to the filtered liquid, a UV light detector disposed an optical path length away from the UV light source for detecting received UV light through the filtered liquid in response to the transmitted UV light, a processor for determining an absorption or a transmission percentage in response to the transmitted UV light and the received UV light, for determining a safe condition, in response to the absorption or the transmission percentage respectively not exceeding or exceeding predetermined criteria, and one or more indicators for indicating that the liquid is safe for consumption to a user, in response to the safe condition.

Embodiments of a gravity filter for potable water comprise a loose filter bed comprising ion exchange resin particles and activated carbon particles, and a porous non-woven filter substrate disposed downstream of the loose filter bed, wherein the porous non-woven filter substrate comprises an impregnated heavy metal scavenger.

A filter for gravity-fed applications, having filter media with a hollow center, the filter being generally prone to a degradation or cessation in fluid flow due to air entrapment or air lock within the filter housing cavity, which develops during filtering. A diffuser element is introduced to pierce the entrapped air bubble, the diffuser element being an elongated structure connected to the filter housing top end cap and extending through the entrapped air bubble to the filter media.

A water filter and infusion pitcher apparatus includes a pitcher housing, a water filter disposed within the pitcher housing, and an infusion apparatus disposed inside the pitcher housing and detachably connected to the water filter. The infusion apparatus constructed to contain and/or hold material such as, for example fruit, vegetables, tea, medicines, flavorings, vitamins, minerals, and/or other items to infuse, seep, and/or dissolve into a liquid within the pitcher housing.

A water treatment cartridge includes a base having a recess therein. One outlet is located in the recess in the base and at least one further outlet is located away from the recess in the base. The outlet located in the recess in the base may be surrounded by an annular wall which projects away from the base of the water treatment cartridge to cooperate with a hopper in which the cartridge is fitted. The outlets can be designed to restrict the flow of water through the cartridge independently of any hopper in which the cartridge is mounted.

An expandable water filtering pitcher having a pitcher with a top portion, a base portion and an inner wall surface defining an internal volume of the pitcher, a spout at the top portion at a pitcher opening, a handle attached to an exterior of the pitcher, a filter adapter mounted within the pitcher top portion. The filter adapter is within a reservoir comprising an opening therethrough from the top portion to the base portion of the pitcher and a reservoir sleeve movably coupled to the reservoir and top portion, at least one of the reservoir and the reservoir sleeve moveable in relation to the other between a retracted position defining a first reservoir volume within the reservoir and reservoir sleeve, and an expanded position defining a second reservoir volume within the reservoir and reservoir sleeve at least 40% larger than the first reservoir volume.

A water container or bottle with integrated disinfection preferably includes a battery compartment, a control printed circuit board (PCB) to manage several parameters including timing, voltage rate, and user-interface. A high voltage power supply is coupled to a set of electrodes to cause an electric discharge. The electric discharge results in a series of reactions in the water that eliminate bacteria and viruses, dissolves organic material, and oxidizes inorganic compounds.

Filters for use in conjunction with valves of the faucet or spigot type, and to filters for use in devices for withdrawing liquids from containers at relatively low pressures, such as gravity feed jugs or other gravity feed reservoirs. A -turn attachment scheme for connecting a filter cartridge to a gravity feed reservoir, such as within a beverage making/dispensing device.
