Machine noise can occur if there is a leak in the system. Ensure all connections are secure and that the water chamber is connected properly. If the noise persists check your filter. Dirty or plugged filters can cause motor noise. Filters should be replaced every 1-3 months to ensure no dust gets into the machine and plugs the motor. If the noise persists please contact our office to discuss potential adjustments to correct this; we may be able to adjust your EPR/pressure relief setting to help. Please note if your machine is over 5 years old it may be time to replace it.
The noise may also be coming from a mask leak which could be a result of the seal being incomplete. This is mostly noticed around the mouth or eye areas. Sometimes, it may be from the exhalation port. Please note that there will be a constant flow of air exiting through the exhalation port of the mask. Every mask has at least one exhalation port. This is an important aspect of your mask because it allows you to breathe out and clear any carbon dioxide from sitting in the mask. This port can be bothersome to some people. Please contact our office to discuss a mask option that has a diffuser cover for the exhalation port
