A: Your mask, headgear and other components should be cleaned on a regular basis. If maintained properly, your mask and headgear should last six to 12 months.

On a daily basis:

Wash the mask or pillows with a soft cloth. Gently wash with a solution of warm water and a mild, clear liquid detergent. Rinse thoroughly, and allow mask or pillows to air dry.

On a twice-weekly basis:

With a soft cloth, gently wash the swivel connector and tubing in a solution of warm water and a mild, clear liquid detergent. Rinse thoroughly and allow them to air dry. On a weekly basis:

Unplug the unit and, using a cloth slightly dampened with water and dish detergent, wipe the outside of the unit. Using a cloth dampened with water only, wipe the outside of the unit again. Use a dry cloth to wipe the unit dry. Make sure it's thoroughly dry before plugging it in again.

On an as-needed basis:

Wash your headgear and/or chinstrap as needed, perhaps once or twice a week. Again using a soft cloth, gently wash each in a solution of warm water and a mild, clear liquid detergent.
