Please refer to the tubing user guide for detailed instructions on cleaning. In general, the air tubing should be removed every day by pulling on the finger grips on the cuff. Hang the tubing in a clean, dry place until its next use. Please note: Air tubing should not be hung in direct sunlight as it may harden over time and eventually crack. Air tubing should not be washed in a washing machine or dishwasher. Every week, patients should remove the air tubing from their therapy device and mask by pulling on the finger grips on the cuff, then wash the air tubing in warm water using mild detergent. They should rinse the tubing thoroughly, hang it up in a clean, dry place, and allow it to dry. They should reconnect the air tubing to the air outlet and mask next time they use the device.
