You should check the mask or nasal pillows after each cleaning. Although silicone is not susceptible to hardening, it can tear. The actual life of the nasal mask or pillows can vary greatly, depending upon use. Replace the mask when it leaks air excessively, there is a tear in the cushion, or it becomes uncomfortable to wear.

Cleaning procedure: Items included are: Mask or nasal pillows, swivels, connectors, and tubing.

Step 1. Remove the headgear from your mask or nasal pillow shell. Disconnect the mask or shell, swivel or Whisper Swivel from the tubing. NOTE: You do not have to remove the support ring, spacer, or rotating connector from the mask before cleaning it, but you may want to do so to clean the parts more thoroughly.

Step 2. With a soft cloth (or a disinfectant cloth), gently wash (or wipe) all the parts of the mask, the shell and pillows, the swivels in a solution of warm water and unscented dish detergent. DO NOT use any cleaners containing fragrance, conditioners or moisturizers as these will leave a residue. Be sure to thoroughly clean the mask cushion flaps or the nasal pillow.

Step 3. Rinse thoroughly. If any part or parts still seem to be oily, wash them again.

Step 4. You can use a white vinegar and distilled water solution, mixing 1 part white vinegar and three parts distilled water. Allow all items to soak for 30 minutes. Make sure you thoroughly rinse the items after disinfecting them. Any residue left on the parts may shorten their useful life and/or irritate your skin.

Step 5. Let every thing dry completely before using them again. To make sure all parts of the system are completely dry, put the system together and run the unit for about 30 minutes before using.

Cleaning the Headgear, Chin Strap, Shell Retainer Strap: These items should be cleaned a minimum of once each month.

Step 1. To maximize the life of the soft goods (headgear, chin strap, comfort strap, shell retainer strap) hand washing with a standard laundry detergent is recommended. NEVER USE BLEACH.

Step 2. Allow headgear to air dry.

Cleaning the Heated Humidifier:

Step 1. Always use distilled water in your humidifier.

Step 2. Discard any water remaining in the humidification chamber if you are not using distilled water.

Step 3. Wash the chamber top, base, deflector, and supply tubing in mild dish washing detergent. Rinse thoroughly and air dry.

Step 4. Inspect the chamber, base, deflector, and tubing to ensure no residue remains after cleaning.
