1. A water reservoir for an apparatus for generating a humidified flow of pressurized breathable air for delivery to an entrance of the airways of a patient for respiratory therapy, the water reservoir comprising:
a reservoir base configured to hold a predetermined maximum volume of water to be used for humidification of the pressurized breathable air;
a reservoir lid pivotally connected to the reservoir base to allow the water reservoir to be movable between an open position and a closed position, the reservoir lid comprising an inlet and an outlet; and
a seal configured to sealingly engage the reservoir lid and the reservoir base when the water reservoir is in the closed position,
wherein the reservoir base includes an overfill protection element having an egress path for water at a predetermined location,
wherein, in the closed position of the water reservoir, the seal blocks and seals the egress path to prevent fluid communication into and out of the water reservoir through the egress path, and
wherein the reservoir base is configured so that, when the reservoir base is rested on a flat surface with the reservoir lid in the open position, the overfill protection element is configured to allow excess water above the predetermined maximum volume of water to spill out via the egress path at the predetermined location if the predetermined maximum volume of water is exceeded.
