Abstract: A liquid filtration and dispensing system stores a liquid, such as water or another beverage, filters the liquid with an integrated component, and dispenses the filtered liquid for use, such as for drinking. The liquid filtration and dispensing system includes a dispenser body for storing a liquid or fluid to be filtered and/or dispensed from the system. A filtration assembly, also known as a “cartridge”, couples to the dispenser body, and includes a filtration mechanism, or space for inserting a filtration mechanism, for filtering liquid stored in and/or expelled from the dispenser body. The filtration assembly may be removable and replaceable once spent. A dispenser capping element couples to the filtration assembly to seal and contain the filtration assembly, and includes a discharge opening for dispensing a filtered liquid from the system. The filtration assembly may also include an air vent assembly to facilitate dispensing of the liquid.

Abstract: A hand-held liquid dispensing apparatus for dispensing a filtered liquid includes a dispenser body defining a reservoir for holding a liquid to be dispensed, a cap assembly including a spout through which liquid is dispensed from the dispenser body, and a filter assembly disposed in the dispenser body and secured to the cap assembly. The filter assembly defines a liquid dispensing flow path extending between the reservoir and the spout and along which liquid flows when being dispensed from the reservoir. The liquid dispensing flow path includes a microporous filtration element having a pore size of about 0.3 microns for effectively removing particulate having a size of 0.3 microns or larger from the liquid being dispensed.
