The AirFit™ F20 Full Face Mask Assembly Kit from ResMed is a combination of the AirFit™ F20 Full Face cushion, mask frame, and elbow; headgear is not included. The F20 Assembly Kit is available in size Small, Medium, and Large due to the size of the InfinitySeal™ cushion. This purchase contains a mask which covers the nose and mouth, and it is available in the selected size only.

  • Wide Range of Visibility
  • Quick Release Elbow with Diffuser
  • New QuietAir Elbow Included With Purchase

InfinitySeal™ Full Face Cushion

Regardless of CPAP pressure levels, the F20 full face cushion is intended to maintain its seal throughout the night. ResMed's AirFit F20™ InfinitySeal™ cushion fastens to the newly designed, flexible frame to improve CPAP results for many users. The technology is designed to become compatible with a variety of face types and structures.

Wide Range of Visibility

The AirFit™ 20 Full Face frame spreads low beneath the eyes and rises high above the ears. The frame attaches to headgear (not included), allowing it to remain steady when the headgear (not included) is pulled taught. The use of a headgear support was eliminated from the design, creating an open line of vision from the bridge of the nose to the top of the forehead. Those who are claustrophobic or enjoy reading and watching TV before falling asleep may respond to the wide range of visibility and the opportunity to enjoy simple activities before bed, once again.

Quick Release Elbow with Diffuser

The AirFit™ F20 elbow extends from a circular attachment which connects to the opening in the middle of the InfinitySeal™ cushion. The round component is lined with many, tiny holes which diffuse the sound of the air as it is being released from the mask, helping to quiet CPAP therapy not only for the user but also their bed partner.

A quick release feature was built into the elbow, creating an easy release from the CPAP hose. If you get up in the middle of the night, slide the CPAP hose from the base of the elbow. Stop or start therapy without the need to disrupt the mask.

New QuietAir Elbow Included With Purchase

ResMed has developed a new QuietAir Elbow for the F20 Series of CPAP masks which is 89% quieter than the previous elbow. This is included for free with your purchases of this mask.

    Important Tips

    Tips to Fit the AirFit F20™ Assembly Kit

    1. Detach the magnetic headgear clips from the base of the cushion, if applicable.
    2. With the headgear attached to the mask frame, pull the mask over your head with the ResMed label facing outward.
    3. Before the mask settles on the face, move the cushion around to ensure it is fitting properly on the bridge of the nose.
    4. With the cushion positioned, pull the lower headgear straps toward the mask and connect the clips to the blue magnet. Note: The lower headgear straps need to fall below the ears.
    5. Lift and pull the tabs located at the top of the headgear to apply or loosen tension for a secure fit. Re-attach the tab to the headgear.
    6. Then adjust the bottom headgear straps in the same manner, if needed.
    7. Join the air tube and elbow together to form one piece.
    8. Insert the elbow into the round opening on the full face cushion, and attach the CPAP hose to the elbow.

    Compatibility Tip:

    At this time, the Standard HumidX™ or HumidX™ Plus are not compatible or available with this mask.

    Cautionary Tip: Magnetic Headgear Clips

    The manufacturer issues the following statement in the product user manual: "Magnets are used in the lower headgear straps and the frame of the AirFit N20. Ensure the headgear and frame is kept at least 50 mm away from any active medical implant (eg, pacemaker or defibrillator) to avoid possible effects from localized magnetic fields. The magnetic field strength is less than 400 mT."

    Cleaning Tips

    It is recommended that the mask be washed before each use or after each use.

    Where Do I Find the Size?

    The frame is one size; therefore, a size indicator is not found on the mask frame.

    The cushion size is printed below the round opening on the mask cushion. A printed black circle with a white letter represents the size of the cushion. The letter S represents a Small cushion, M represents a Medium cushion, and L represents a Large cushion.
