Disclosed is a filter attachment that removably couples with a faucet or other vessel. The attachment includes a flexible cover holding the filter on the vessel and that acts as a pressure relief mechanism if the water pressure of the faucet is above a predetermined threshold. Another flexible cover may be located on the opposite side of the attachment to allow reversible use and cleaning by backwashing. The attachment may further include a removable cap on one side that includes a flexible cover and that couples to the remainder of the attachment in a removable manner so as to allow other fitments to couple to the attachment.

A dispensing container facilitates convenient chilling and dispensing of water, with a filtration arrangement provided to promote water purity. The system includes a generally cylindrical filter assembly positionable within a liquid container, so that the filter assembly is generally submerged in the water within the container. The filter assembly can be operably connected to a liquid spigot, so that when the spigot is opened, liquid within the container flows through the filter assembly and out of the container, through the opened liquid spigot. Convenient use by consumers is promoted by the provision of a filter protector, comprising a selectively removable, shrink-wrap sleeve surrounding the filter assembly. The shrink-wrap sleeve is positioned on the filter assembly to protect the assembly prior to removal of the shrink-wrap sleeve. A removable tape element is provided to temporarily connect the filter assembly to the spigot prior to use.

Provided are faucet inlet hose assemblies comprising an integrated filter. A faucet inlet hose assembly having an integrated filter comprises a hose comprising a first hose end and a second hose end; a first coupling fitting, wherein the first hose end terminates at the first coupling fitting; a second coupling fitting, wherein the second hose end terminates at the second coupling fitting; a hose connector connected to the first hose end; and a filter at least partially within the first coupling fitting and coupled to the hose connector.

A filtration system for a pull-down or pull-out faucet includes a multi-channel hose configured to fluidly couple to a spray head, a water filter configured to provide filtered water, and a diverter-equipped T-connector. The T-connector has a first branch configured to receive unfiltered water from a valve cartridge of the faucet, a second branch configured to receive filtered water from the water filter, and a third branch configured to deliver filtered and unfiltered water from the first and second branches to different channels of the multi-channel hose. The spray head also includes an activation switch configured to allow selective output of filtered and unfiltered water from the spray head.

A filter device comprises a first filter mechanism and a second filter mechanism, the first filter mechanism is connected to the second filter mechanism, wherein the first filter is configured to filter disinfectants, impurities, and organic matters in water, and the second filter is configured to filter germs in the water. A faucet water purifier comprises above filter device.

A water filter faucet having a filter element life determining functionality comprises a faucet body having a valve disposed therein. A rotatable handle is arranged on the faucet body and configured to control an operation of the valve. A monitoring device is arranged on the rotatable handle and electrically connected to a control circuit configured to receive a monitoring signal from the monitoring device and count a time. The control circuit is connected to a warning device configured to warn of that the service life of the filter element is to an end.
