The only routine care a PAP machine requires is regular cleaning or replacement of the air intake filters. This is important to keep the internal parts from accumulating particulates. Disposable filters should be checked at least every other week and generally replaced every 2-4 weeks or when they appear dirty. The non-disposable filter may be rinsed with clear running water if they appear dirty, and reinserted into the machine after ample time to air dry. Non-disposable filters should be replaced every six months.
Keep the area around your machine clean. Remove any dust from around the machine to improve the air quality delivered to your machine. Keep the air intake of the machine unblocked. Curtains, bedding, and papers can easily block the air intake of your machine, reducing the airflow and increasing work on the blower motor.
Manufacturer warranties are voided by water damage to the machine. To avoid this, remove the chamber from the humidifier and then remove the humidifier from the machine rather than transporting them together. If a humidifier is used you should empty the water from the chamber every morning. Accidents happen. If a family pet or family member moves the machine and humidifier with water in the chamber it is more likely that water could be spilled into your machine.
