ABSTRACT:
A gravity-flow water filter cartridge for use in a drinking water carafe or the like includes a high-surface area cyst reduction filter element disposed in a water-retaining reservoir within the cartridge; the reservoir retains sufficient water between filtering and during dispensing cycles to maintain the filter element in a fully immersed state, whereby the primed (air-free) condition of the filter necessary for fast gravity flow at high cyst reduction efficiency is maintained.
