This is the replacement nasal pillows for the ResMed AirFit P10 Nasal Pillows System and ResMed AirFit P10 Nasal Pillows System for Her (XS, S, M or L).
These were replacements for a worn out set to go with my headset. My comments related to CPAP filters pretty much covers this purchase too. Impressed by Isabelle and the help she provided in a consult even though I'd not purchased my machine from here three or so years go. However, will get any replacement from here when that Resmed reaches its service lifespan.
