How to Reduce AirMini Noise: Practical Tips for a Quieter CPAP Experience

The ResMed AirMini is one of the smallest and most popular travel CPAP devices on the market. Light, compact, and powerful, it’s designed for users who want effective sleep therapy on the go. But let's be honest—some users find the AirMini a bit too noisy for their liking, especially when compared to full-sized machines like the ResMed AirSense 10, Resmed Airsense 11, Fisher&Paykel SleepStyle or Philips Dreamstation.

If you’re finding your AirMini louder than expected, don’t worry — there are several ways to reduce the noise and enjoy a more comfortable night’s sleep.

Why Is the AirMini Noisier?

The AirMini’s compact size means it doesn’t have as much room for internal sound insulation. This means:

More noticeable airflow noise
Higher pitch sound near the machine or tube
Audible exhalation sounds through the HumidX waterless humidification system

The good news? With the right accessories and setup, you can significantly cut down on these disturbances

1. Check Mask Fit and Adjustment

A snugly fitting mask can minimise air leaks, which often contribute to noise near the mask. Make sure that your mask is not too tight or too lose and adjust the straps according to your facial anatomy for a comfortable and secure fit. You may also consider using a mask with softer padding or quieter air vent for optimal noise reduction.

2. Examine the Tubing Connections

Ensure that the connections between the AirMini tube, mask, and HumidX™ cartridge are secure and properly connected since loose connections can create noise. Push the tubing firmly over the connectors to prevent air leakage and unnecessary whistling sounds.

3. Secure the Device

The AirMini may produce some vibrations during operation. Placing the machine on a level, sturdy surface or using a non-slip mat can minimise vibrations-related noise.

4. Distance the Device from Your Sleeping Area

Sometimes, small adjustments can make all the difference:

Place the device on a soft surface (like a folded towel) to dampen vibration noise.
Keep it lower than your head to reduce direct sound paths.
Avoid placing it on hard surfaces like bedside tables, which can amplify sound.

By increasing the distance between you and the AirMini, you may reduce the perceived noise level.

5. Maintain the AirMini

Regular maintenance and cleaning of the AirMini device, including the replacement of the air-inlet filter and HumidX cartridge, can help maintain optimal airflow and reduce noise created by clogged filters or cartridges.

Always consult with your healthcare provider if you have concerns about the noise level of your CPAP therapy as they may have suggestions or offer solutions specific to your situation.

There are optional accessories that may make your AirMini a quieter CPAP experience

Use the ZephAir Adapter with Any Standard Mask

Don't love the limited mask options for AirMini? Using a ZephAir adapter, you can connect almost any regular CPAP mask to your AirMini, bypassing the HumidX system — which is often the source of noise. Pair this with your quieter full-size mask and experience a significant reduction in noise.

👉 Compatible with:

Add a Noise Muffler to the Tube

A simple in-line tube muffler can dramatically reduce the “whooshing” sound from the AirMini’s airflow. This accessory is inserted between the machine and the CPAP tube and is compatible with ZephAir setups.
