  • Replace every 6 months or sooner if signs of wear, cracks, or discoloration appear.
  • Ensure a secure fit in the CPAP and BiPAP machine to prevent leaks and maintain proper function.

Everything you need to know about the HumidAir Water Chamber

Compatible with AirSense 11

This water chamber is specifically designed for the ResMed AirSense 11 CPAP machine, ensuring a perfect fit and seamless integration. It is not compatible with older ResMed models.

Designed for Add Humidification

It adds moisture to the air before it reaches your airways by heating the water in the chamber as the CPAP machine draws in room air. This warm, humidified air is then delivered through the tubing and mask, helping to prevent dryness in your nose and throat. With a 380 mL capacity, the chamber provides enough water to maintain consistent humidity levels all night

Reduces the Risk of Respiratory Infections

Proper humidification provided by the HumidAir 11 Water Chamber can lower the risk of respiratory infections by keeping your airways moist and reducing irritation.

Essential for Effective Humidification

The water chamber plays a crucial role in your CPAP therapy by adding moisture to the air, reducing dryness and irritation in the throat and nasal passages. This helps improve comfort, making it easier to stay consistent with therapy.

Compatible with AirSense 11 and AirCurve 11

Designed specifically for ResMed AirSense 11 CPAP and AirCurve 11 BiPAP, this water chamber ensures a secure fit and reliable performance. It is not compatible with older ResMed models like the AirSense 10 or S9.

Reduces Dry Mouth and Nasal Congestion

By adding humidity to your therapy air, the chamber helps prevent common CPAP side effects such as dry mouth, nasal congestion, and throat irritation, making sleep therapy more comfortable throughout the night.

Prevents Rainout and Condensation

The integrated humidification system helps regulate moisture levels, preventing excessive condensation buildup in the tubing. This helps maintain stable therapy pressure and reduces disruptions caused by water pooling in the hose.

Durable and Long-Lasting Materials

Constructed from injection-molded plastic, stainless steel, and a silicone seal, this chamber is built to withstand daily use and repeated cleaning while maintaining its structural integrity over time.

Standard and Dishwasher-Safe Options

The water chamber is available in two versions—a standard model that requires hand washing and a dishwasher-safe model for added convenience. This makes regular maintenance easier, ensuring a hygienic and long-lasting humidification system.

Recommended Use of Distilled Water

Using distilled water helps prevent mineral buildup inside the chamber, ensuring optimal humidification and extending the life of both the water chamber and the CPAP machine. Tap water can cause scaling, which may impact performance over time.

Easy to Clean and Maintain

For best results, the chamber should be emptied daily and washed with mild soap and warm water. If using the dishwasher-safe model, it can be placed on the top rack for a thorough and convenient cleaning process.

Why do CPAP machines have humidifiers?

CPAP humidifiers add moisture to prevent dry mouth, throat irritation, and nasal congestion caused by pressurized air.

Are all CPAP humidifiers the same?

No, there are two types: - Integrated humidifiers (built into the CPAP machine) - Standalone humidifiers (separate units that connect to the CPAP)

Do I have to use a CPAP humidifier?

No, but it helps reduce dryness and discomfort. If you experience dryness, adding a humidifier can improve comfort.

What type of water should I use in my CPAP humidifier?

Use distilled water to prevent mineral buildup and bacteria growth. Avoid tap or bottled water.

How often should I clean my CPAP humidifier?

Daily: Empty and rinse with warm water. Weekly: Wash with mild soap, rinse well, and let it air dry.

Why is there water in my CPAP mask or hose?

This is rainout, caused by humidified air cooling in the hose. Using heated tubing or a hose cover can help.

Can I travel with a CPAP humidifier?

Yes, but some travelers prefer to turn off the humidifier to reduce bulk. If flying, empty the water chamber before packing.

When should I replace my CPAP humidifier chamber?

Every 6 months, or sooner if you notice discoloration, cracking, or buildup that doesn’t clean off.
