·        Filter for S9 / AirSense 

Proper air filtration starts with an air filter on the CPAP machine  by catching dust, animal hair and pet dander. Most CPAP machines include a standard disposable filter which should be changed when dirty or after a month.

·         These Disposable Filters fit the ResMed S9™ Series and AirSense™ 10 CPAP Machines.
