A porous carbon material having a value of a specific surface area by a nitrogen BET method of 1×10.sup.2 m.sup.2/g or more, a volume of fine pores by a BJH method of 0.3 cm.sup.3/g or more, and a particle size of 75 μm or more, alternatively, a porous carbon material having a value of a specific surface area by a nitrogen BET method of 1×10.sup.2 m.sup.2/g or more, a total of volumes of fine pores having a diameter of from 1×10.sup.−9 m to 5×10.sup.−7 m, obtained by a non-localized density functional theory method, of 1.0 cm.sup.3/g or more, and a particle size of 75 μm or more.

Provided are systems for atmospheric water generation, comprising a dehumidifier configured to receive air, comprising a desiccant core, a heater configured to heat at least a portion of the desiccant core, and a condenser system configured to collect water from the desiccant core when the desiccant core is heated by the heater; and a fluid filter configured to filter one or both of the air, prior to the air dehumidifier receiving the air, or the water, after the water is collected by the condenser system.

Provided are water treatment cartridges, in particular gravitational flow treatment cartridges, that include a flow restriction element.

A container assembly is disclosed. The container assembly includes a container that contains a volume. Selected portions of the container assembly may provide indication to a user of features or status of the container assembly.

The invention relates to container bodies configured to be used in filter-as-you-pour systems, where filtering is achieved as the user pours water from the container. Such container bodies may have an undivided internal storage volume, so as to not include a reservoir compartment for unfiltered water. They may be part of systems configured to filter water both as water is introduced into a container body of the system and as water is poured from the container body of the system. The filter assembly may be attached to the container body at a location proximate the outlet of the system. Filter media of the filter assembly may comprise an activated carbon textile material that presents a curved surface to water passing through the filter assembly. The container body may be configured as a pitcher, carafe, water bottle, jug, or other shaped container.

The claimed invention relates to systems, devices, and methods of using the devices for fast flow and reduced waste over the lifespan of a permeable filter. The invention includes a fluid filtering system with a fluid reservoir with a cavity and lid to capture a permeable filter. The permeable filter is easily replaceable.

A portable water filtration apparatus has a top panel, a mounting surface, an electric pump mounted to the mounting surface, at least one filter, and at least one filter housing coupled to the top panel, with the at least one filter filtering water from the pump. The portable filtration apparatus has a housing, such as a bucket, to fully contain the components and which may be used for collecting either filtered or unfiltered water.

The claimed invention relates to systems, devices, and methods of using the devices for eliminating air locks by using a filter cartridge with a truncated cone shaped lid that allows air to naturally flow to the highest point of the filter cartridge. The lid including a hole for releasing air that can slow or stop the filtration process. The filter cartridge further including a foam spacer to prevent filter media from escaping the filter cartridge.

A filtering container for liquids, in particular water. The filtering container includes a main body, a gripping portion which is configured to be gripped by a user for lifting the container and pouring out the liquid contained therein, a closure for an opening which is defined in the main body which includes a filtering element which is arranged in a position to intercept the liquid being discharged from the main body, a dispenser for the liquid which is configured in such a way that the liquid is dispensed through a dispensing zone for the liquid which is defined adjacent to a side wall of the main body and a ventilation pipe which opens inside the main body in a ventilation zone and extends in the form of an elongate element towards the interior of the main body.

An on-demand filter structure including a first hydrophilic protective layer comprising a first surface exposable to a stream of water. A contact area on the first surface receives the stream. The first hydrophilic protective layer receives the stream and distributes water out a second surface, primarily using gravity. An activated carbon felt (ACF) layer is adjacent to the second surface, wherein the ACF layer is configured for water filtration, primarily using gravity. A second hydrophilic protective layer includes a third surface adjacent the ACF layer and a fourth surface. The third surface receives filtered water from the ACF layer, and the fourth surface expels the filtered water primarily using gravity, wherein the first and second hydrophilic protective layers sandwich the ACF layer. A cross section of the first hydrophilic protective layer, the ACF layer, and the second hydrophilic protective layer has a curvature.
