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.

A method for a water bottle comprising, coupling a cap to bottle housing such that an interior of the water bottle and the cap form a water-tight region, receiving a button push on the cap, determining with a light sensor whether visible light is present in a vicinity of a UV LED light source disposed within the cap, in response to the push of the button, initiating providing with a UV LED light source UV light to the interior in response to the push of the button and in response to absence of the visible light within the vicinity of the UV LED light source, and inhibiting providing with the UV light to the interior after a period of time after the initiating providing UV light to the interior or in response to determining the visible light being present in the vicinity of the UV LED light source.

The invention relates to water purification devices of gravity type, intended for final purification of tap water and other liquids for household purposes.

From the state of the art water purification devices of gravity type usually consist of three elements: container for the raw liquid and container for purified liquid, which communicate with each other through water filtration cartridge. Raw liquid is poured into container for raw liquid and under gravity forces it flows through filtration cartridge and collects in the container for purified liquid. As it is known filtration cartridge consists of filtration zone and venting zone. Venting zone is executed as the lid with openings for raw liquid inflow and air outflow, and filtration zone. Filtration zone has in its bottom not less then one opening for purified water outflow and as usual is filled with filtration material. For example granulated and fibrous sorbents can be used as filtration materials in such purification devices.

Filtration cartridge of liquid purification device consists of filtration zone and venting zone, filtration zone in its turn consists of housing filled with the filtration material and not less than one opening made in the bottom of the housing, venting zone consists of fixation means and the lid, characterized in that filtration material has multi clustered interconnected structure, and venting zone is performed so as to retain and keep the main structure of the filtration material inside the housing of then filtration cartridge, by means of that fixation means is the first retention barrier and is made as a grid, the size of meshes of grid preferably is not more than average size of the filtration material cluster, and the lid is made as the second retention barrier and is made with the meshes which size is preferably not less than ten times less than size of the openings of the fixation means.

A water filtration system includes a raw water reservoir that holds raw water. The system also includes a gravity filtration assembly to remove particles from the water as it passes through from the raw water reservoir. The filter of the assembly includes immobilized filter media within an enclosure.

A filter for holding filtration media that may be used, for example, to filter domestic water. In one embodiment, the filter is configured to be used with a reusable cartridge and closure system enabling the use of the filter in water pitchers, including reusable gravity-flow water filters.

A system includes memory banks that store data and a data path coupled to the memory banks that transfers the data. The system also includes a latch that gates the data path based on a clock signal in the system. The system further includes interface circuitry coupled to the data path that sends an instruction to the memory banks to transmit the data on the data path in response to receiving a first rising edge of the clock signal. The interface circuitry also outputs gated data in response to receiving a second rising edge of the clock signal. The latch gates the data path to store the gated data in response to receiving a falling edge of the clock signal.
