Why is my ResMed P10 mask making a whistling or hissing noise?Updated 2 months ago
Issue: A whistling sound often comes from the vent holes clogging with debris or moisture buildup.
Solution: Clean the mask regularly, ensuring the diffuser vents are clear. If condensation is the issue, try using a heated hose or a hose cover to reduce moisture buildup.
Cleaning the vents will also make it easier to exhale.
