Abstract:

A cartridge for treating water, the cartridge capable of releasably engaging a water treatment device. The cartridge includes a housing, an inlet for introducing untreated water into the cartridge, an outlet port for egress of treated water from the cartridge, and a treatment media for treating untreated water The treatment media is in fluid communication with the inlet and the outlet port. The cartridge further includes a first tube having an inside surface, an outside surface, a proximal end, and a distal end, where the inside surface and/or the outside surface is a sealing surface. The cartridge further includes a second tube having an inside surface, an outside surface, a proximal end, and a distal end, where the inside surface and/or the outside surface is a sealing surface. The first tube extends from the housing and surrounds the outlet part. At least a portion of the first tube or the second tube surrounds the other such that a gap is formed between the first tube and the second tube.

Abstract:

A water filter device for treating untreated drinking water, wherein the water filter device may comprise a connector for providing fluid communication between the water filter device and an untreated drinking water source. The water filter device may comprise a low-pressure water for treating untreated drinking water, the water filter may comprise a water filter material. The water filter may comprise a F-BLR of greater than about 2 logs. The water filter device may comprise a storage housing in fluid communication with the low-pressure water filter. The water filter device may comprise an automatic shutoff valve for arresting the flow of treated drinking water into the storage housing. The water filter device may comprise a dispenser for dispensing treated drinking water from the storage housing. The treated drinking may enter into the storage housing at the rate of at least about 5 mL/min until activating the automatic shutoff valve, such that the flow of treated drinking water into the storage housing is arrested. The water filter device may be a non-electric water filter device.
