Breathable gas apparatus with humidifier

A CPAP device for delivering pressurized, humidified breathable gas for a patient, the CPAP device comprising:

• a humidifier base unit with an engagement face configured to directly attach to and detach from a flow generator, the humidifier base unit comprising an air inlet at the engagement face;
• and
• a water container with an air inlet and an air outlet, the water container being removably positionable at least partly within the humidifier base unit;
• and
• an elastomeric face seal with an aperture, the elastomeric face seal being configured to sealingly abut against an external sealing surface of the water container surrounding the water container air inlet,
• wherein the humidifier base unit and the water container are configured to create a sealed air path upon positioning the water container at least partly within the humidifier base unit and upon the water container sealingly engaging the elastomeric face seal, and
• wherein the sealed air path extends at least through the humidifier base unit air inlet, through the elastomeric face seal, through the water container and to an outlet of the humidifier base unit.

• and
• a water container with an air inlet and an air outlet, the water container being removably positionable at least partly within the humidifier base unit;
• a first elastomeric face seal with a first aperture, the first elastomeric face seal being configured to sealingly abut against a substantially flat, external portion of the water container surrounding the water container air inlet without any portion of the water container entering the first aperture;
• a lid attached to the humidifier base unit, the lid being pivotable between an open position and a closed position;
• and
• a second elastomeric face seal with a second aperture, the second elastomeric face seal being provided to a bottom side of the lid and a portion of the second elastomeric face seal being configured to sealingly abut against a portion of the water container surrounding the water container air outlet without any portion of the water container entering the second aperture,
• wherein the humidifier base unit and the water container are configured to create a sealed air path upon positioning the water container at least partly within the humidifier base unit and upon the water container sealingly engaging the elastomeric face seal, and
