Made With Durable Components and Comes With a Three Month Warranty

The AirSense 11 Water Chamber is made with injection-molded plastic, stainless steel, and a silicone seal. The product has a maximum capacity of 380 mL and includes a 90-day warranty. To use, place the device on a level surface that’s lower than the placement of your head. This position will prevent your mask and tubing from filling with water.

Ultimate Comfort: Use Distilled Water for Best Humidification Results

Though the AirSense 11 Water Chamber is easy to care for, there are a few tips that we recommend to prolong its lifespan. Always use distilled water at room temperature, and regularly check the tub for leaks and cracks. This product should be wiped thoroughly with a clean disposable cloth each day and dried away from direct sunlight.

Coordinating CPAP Machine Provides Replacement Reminders

If you do notice leaks or cracks along the AirSense 11 Water Chamber, you should replace it immediately. Otherwise, if you use an AirSense 11 machine, you can use the Humidifier Set function to set a recurring notification to remind you to replace the water tub.

Maintain Excellent Humidification Output: Avoid Using Oils or Perfumes

Certain additives like scented oils and perfumes may cause premature deterioration of the tub materials and can reduce the humidification output of your equipment. Additionally, the device should not be placed on its side or overfilled, as these practices can lead to a reduced motor life or the potential of water entering the tubing.

Maximum Fill Level Tips

• Do not fill the water tank above the maximum fill line. If you overfill the humidifier tub, it may result in damage, caused by excess water leaking out of the tank inlet.
• When disconnecting the hose from the tank outlet, be careful to ensure that the hose is not holding water. Water could travel through the hose and into the machine, damaging it.
• Use only room temperature distilled water in the water chamber tub. Do not put any chemicals or additives (like essential oils) into the water. Additives can irritate your mouth or throat and may be harmful. Tap water can leave hard deposits that create more work for your CPAP machine and affect the quality of your CPAP therapy air and its pressure.
• Remove the tank, empty all water, and replace the empty tank before transporting the humidifier base. Leaking water from your humidifier chamber can cause damage to your machine.
• Do not attempt to fill the water tank while it is inside the humidifier.
• Do not turn the humidifier on without the water tank installed. The Humidifier number setting must remain on 0 if there is no water in the water tank.

Cleaning the Standard AirSense 11 Water Chamber

The standard water tub should be washed weekly using warm water and a mild detergent, rinsed well, and allowed to dry out of direct sunlight. The standard water chamber is not dishwasher safe and should only be hand-washed.
