Standard air filters provide effective air filtration for ResMed S9™ and Air 10 sleep therapy devices—helping protect the device from contamination, as well as helping patients breathe clean air. These disposable filters trap large floating particles and other contaminants.   
These filters have been tested against our devices to ensure the highest standards of patient care and ease of use. 
These disposable CPAP air filters are designed for use with AirSense™ 10, AirCurve™ 10 or S9™ series devices to filter the air delivered during treatment. 
The filters are easy to fit and should be replaced biweekly (or whenever the filter is damaged or inoperative) for a healthier therapy experience.
