1. A continuous positive airway pressure (CPAP) apparatus to supply pressurized breathable gas to a patient, said apparatus comprising:
- a flow generator having a gas inlet and a gas outlet;
a humidifier having a gas inlet coupled to the gas outlet of the flow generator; and
a filter operatively positioned between the gas outlet of the flow generator and the gas inlet of the humidifier,wherein said humidifier comprises;
a hollow body adapted for at least partial filling with water to a predetermined maximum water level;
a heating element to heat the water in the body; and
a flow divider adapted to divide the interior of the body above the maximum water level into a relatively dry gas region and a relatively wet gas region,wherein the gas inlet to the body and a gas outlet from the body is above the maximum water level, andwherein the flow divider of the humidifier includes a flow dividing plate that divides the interior of the body above the maximum water level into a relatively dry gas region above the plate and a relatively wet gas region below the plate.
