Struggling with dryness, irritation, or discomfort during your CPAP therapy? The airsense humidifier is a vital component designed to make your treatment smoother and more comfortable. By adding moisture to the pressurized air from your AirSense CPAP machine, the humidifier combats dryness in your airway, which can improve your overall therapy experience. In this guide, we’ll explore how to use the airsense humidifier effectively, maintenance tips to keep it running optimally, and the ways it enhances your nightly sleep therapy.

Understanding the AirSense Humidifier: Features and Benefits
What Is the AirSense Humidifier?
The airsense humidifier is an integrated accessory available for the AirSense CPAP devices designed by ResMed. It gently adds moisture to the flow of air that you breathe through your mask, reducing common side effects like dry mouth, nasal congestion, and throat irritation. This heated humidification system works alongside your CPAP therapy, ensuring that the air you receive is comfortable and prevents the irritation caused by dry, cool airflow.
Key Benefits of Using the AirSense Humidifier
- Prevents dryness: Moisturizes the airway, reducing dryness in your mouth, nose, and throat.
- Enhances comfort: Warmer, humidified air minimizes discomfort and encourages better adherence to therapy.
- Reduces congestion: Keeps nasal passages moist, lessening congestion and irritation.
- Improves sleep quality: Comfort improvements help users maintain consistent therapy throughout the night.
- Compatible integration: Seamlessly connects with AirSense CPAP units for easy setup and control.
How to Use Your AirSense Humidifier for Maximum Comfort
Setting Up the Humidifier
Getting started with the airsense humidifier is straightforward. First, ensure the humidifier water chamber is properly installed onto your AirSense CPAP machine. Use only distilled or purified water to fill the chamber, avoiding tap water to prevent mineral buildup and bacteria. Fill the tank to the indicated maximum level and securely close it to prevent leaks.
Adjusting Humidity Levels
The AirSense humidifier allows you to customize the humidity level to suit your comfort needs. Most AirSense models feature a touchscreen interface where you can adjust this setting. If you experience a dry throat or nasal passages, try increasing the humidity gradually. Conversely, if you notice condensation (also called rainout) inside your tubing or mask, lowering the humidity can help. Some AirSense devices also offer automatic climate control when used with heated tubing, intelligently maintaining optimal temperature and moisture levels based on room conditions.
Maintaining and Cleaning the AirSense Humidifier
Daily Cleaning Checklist
Regular cleaning is essential to keep your airsense humidifier functioning properly and hygienically. Here’s what to do daily:
- Empty and rinse the water chamber with warm water.
- Wipe down the inside of the chamber with a soft cloth to remove residue.
- Allow the chamber to air dry fully before refilling.
Weekly Deep Cleaning Steps
Set aside time weekly for a deeper clean to prevent mold and bacterial growth:
- Remove the water chamber and soak it in a solution of one part white vinegar to nine parts water for 20–30 minutes.
- Rinse thoroughly under warm water to remove all vinegar.
- Clean the exterior of the humidifier and the CPAP device with a dry or slightly damp cloth.
- Dry all components completely before reassembling.
Important: Never use harsh chemicals, bleach, or abrasive tools when cleaning. Also, avoid washing the tubing in a dishwasher or washing machine to protect its integrity.
Tips to Maximize Therapy Comfort with the AirSense Humidifier
Use Heated Tubing for Consistent Humidification
Pairing your airsense humidifier with heated tubing enhances therapy comfort by keeping the air warm and moist throughout delivery. Heated tubing prevents condensation buildup inside the hose, which can cause rainout and disrupt your sleep. The ClimateLineAir heated tube, specifically designed for AirSense devices, auto-regulates temperature to a comfortable level.
Adjust Ramp Time and Humidity Together
The AutoRamp feature allows your CPAP pressure to start low and gently increase once you fall asleep, promoting easier transition into therapy. When used together with the humidifier, adjusting ramp time and humidity can significantly improve comfort—especially for new users sensitive to airflow sensations. Experiment with combining different ramp durations and humidity levels to find your ideal settings.
Common Issues and Troubleshooting Your AirSense Humidifier
Condensation (Rainout) in the Tubing
Excess moisture may accumulate in your tubing if the humidifier settings are too high or room temperature is low. To reduce condensation:
- Lower the humidity level incrementally.
- Use heated tubing to maintain air temperature.
- Increase room temperature if possible.
- Position the tubing so gravity helps drain excess water away from the mask.
Water Leaks from the Humidifier Chamber
Leaks can occur if the water chamber is overfilled or not correctly seated. Always fill the chamber only up to the fill line and ensure it’s fully clicked into place before use.
Unusual Odors or Taste
If you notice a strange smell or taste from the humidified air, it’s time to clean the chamber thoroughly and replace the water daily. Using distilled water helps prevent mineral buildup and odors.
