Funny noises may suggest you have an issue with your cushion seal and require re-fitting your mask.
If your mask is making some burping or blurting sounds, it's likely that you have an issue with your cushion seal. This can usually be solved by re-fitting your mask.
More often than not the sound comes from the areas that touch your cheeks, so consider tightening the bottom straps of your mask. Keep in mind that even the best-fitting masks may still have some minor leaks, but there should generally be minimal leak from everywhere other than the vent.
Please note: Your mask should be fitted with any false teeth removed as this can also affect the seal of your mask.
If the noise does not subside, consider contacting us to arrange an appointment with one of our friendly sleep coaches on 1800 737 633 for a mask fitting.
