We advise our clients to clean their mask, tubing, and water chamber weekly with warm water and a mild unscented soap, though sooner if you’re prone to skin irritations or sickness. If you read online CPAP forums, you’ll see it ranges from daily, to never. The best recommendation is to use a cleaning schedule you are most comfortable with, whatever that schedule may be.
Unfortunately due to health and hygiene protocols we are unable to refund purchases made unless they are factory defects.
