CPAP Mask Noise When Inhaling

CPAP masks can eventually make a whistling  noise over time. This does not mean your mask is defective. You can use some simple remedies to go to sleep with a quiet mask.

Is Your CPAP Mask Making a Whistling Noise?

A noisy CPAP mask can interrupt your sleep just as much as your sleep apnea. Don’t abandon your CPAP therapy because it’s too noisy.

Why Does My CPAP Mask Whistle?

Loose connections, damaged tubing, or improper mask fittings can allow the high-pressure air from your CPAP machine to escape as a high-pitched whistle.

How to Stop a CPAP Mask from Whistling?

Problem in Mask Fitting

A CPAP mask that does not fit properly will allow air to leak out at higher pressures. Make sure the seal around your mask is secure. Use mask wipes or warm, soapy water daily to remove oil and dirt residue on your CPAP cushion. Reference your mask's user guide to determine if your mask size is too big or small.

• Full face masks: cover from bridge of nose to just below bottom lip
• Nasal masks: cover from just under nose bridge to just above upper lip
• Nasal pillow masks: should fit comfortably inside the nostrils with minimal effort.

You may need a larger or smaller mask size if it does not fit properly. If your cushion is damaged, be sure to replace it immediately. Any one of these issues could be contributing to a whistling CPAP setup.

Problem in Hose Connection

CPAP tubing is very important; it's what allows the air being generated by the CPAP machine to travel to the user airway, keeping it open. If the tube is improperly connected, it could be allowing air to leak out, resulting in whistling noises. Ensure the hose is securely attached to both the CPAP machine and the mask.

Hose Needs to Be Replaced

A worn-out hose may develop tears or cracks allowing air out. If you find damage to your hose, replace it. This should be one of the first steps taken, as it can generally be the least expensive.

CPAP Machine Is Too Loud

Some CPAP machines are simply noisy. So it may not be your CPAP mask at all. Consider a new CPAP machine with quieter performance. 

Resolving CPAP Mask Whistling Problems on Different Types of Masks: 

Hissing Sound on Full Face CPAP Masks

Full face masks can often produce loud hissing sounds when in use. This is usually due to condensation build-up as air escapes through the vent holes.

Reducing the temperature level of the heated humidifier to a comfortable level will help prevent tube condensation and the associated hissing that comes with it.

Whistling Problem on Nasal CPAP Masks

Nasal masks are also susceptible to whistling or hissing problems. One possible reason is that the tiny vent holes in your mask have become clogged. Try cleaning these holes with a toothpick or hard bristle brush to stop the whistling.

Whistling Sound on Nasal Pillow CPAP Masks

The whistling sound from nasal pillow masks typically comes from a high humidifier temperature, so be sure to adjust the temperature to a lower level.
