You’ve probably heard of the ResMed AirFit N20, N30i, P10, P30i, F20 and F30. Have you ever wondered what the P, N and F mean??

N: The ‘N’ in AirFit N20 & AirFit N30i means “nose”. These are masks that will deliver CPAP therapy through the nose. The AirFit N20 sits over the nose and the AirFit N30i seals just under the nostrils.

P: The ‘P’ in AirFit P10 and AirFit P30i means pillow. These masks will deliver CPAP therapy directly through the nostrils, the AirFit P10 & P30i seal inside the nose.

F: The ‘F’ in AirFit F20 & AirFit F30 means full face. Full face masks create a seal over both your nose and mouth. The AirFit F30 seals under the nose and over the mouth whereas the AirFit F20 mask seals over both the nose and the mouth.

With so many CPAP masks out there, this is a simple way to differentiate.
