초록

A gravity-flow water filtration cartridge is disclosed herein. The cartridge includes a housing having a compressed bed of ion-exchange resin disposed within an upper region thereof and a high surface area cyst-reducing filter element that is disposed within a lower thereof. The housing includes a middle chamber which separates the compressed bed of ion-exchange resin from the cyst-reducing filter element. The housing further includes a hydrophobic air vent conduit having an entry end that is positioned above a topmost surface of the cyst reducing filter...
