Abstract:
Embodiments of water filters comprise a filter housing configured to be disposed in a pour tray of a water filter pitcher, wherein a filter media cartridge is disposed inside the filter housing. The filter housing includes a housing floor, housing sidewalls extending upwardly, away from the housing floor, and at least one filter housing outlet disposed in one or more of the housing floor or the housing sidewalls. The filter media cartridge includes filter media, where the filter media cartridge comprises a cartridge floor spaced above the housing floor, cartridge sidewalls extending upwardly, away from the cartridge floor, and at least one filter media cartridge outlet disposed along one or more of the cartridge floor or the cartridge sidewalls. The water filter pitcher further includes a riser extending upwardly, away from the housing floor, and spaced between the housing sidewalls and the cartridge sidewalls, where the riser extends a distance above the cartridge floor. The riser forms a conduit volume.
