The Foundation of a Good Night's Sleep.

As a certified Respiratory Therapist and Sleep Tech, I always tell my patients that the CPAP mask cushion gets all the attention, but it's the headgear that does all the work. It's the silent partner responsible for maintaining a stable and effective seal all night long. Over time, straps lose their elasticity, leading to leaks and the need to over-tighten, which causes discomfort. Replacing your headgear regularly is the most important—and affordable—step you can take to maintain the performance of your sleep therapy.

Why a Fresh Headgear is Essential

This is the official, genuine replacement headgear for the innovative ResMed AirFit F40 mask. Made from the same soft, plush, and breathable materials as your original, it restores the secure-but-gentle fit you need for a comfortable night. A new headgear provides the proper tension without pressure points, ensuring your mask seals correctly at the prescribed air pressure. This simple replacement can be the difference between a frustrating night of constant adjustments and a restful, uninterrupted night of restorative sleep. It is an essential part of your CPAP supply refresh schedule.

The ResMed AirFit F40 headgear shown connected to the F40 mask frame to illustrate its use as a replacement part.

How to Replace Your Headgear

  1. Disconnect the magnetic clips on your old headgear from the mask frame.
  2. Unthread the old upper straps from the top slots of the mask frame.
  3. Thread the new upper straps through the same slots, ensuring the ResMed logo is facing out.
  4. Reconnect the lower magnetic clips to the mask frame. Adjust all four straps for a comfortable, snug fit.

What Our Customers Are Saying

"My old headgear was getting all stretched out and causing leaks. This new one is a perfect fit, just like when the mask was new. It's soft and the seal is tight again. Glad I replaced it instead of fighting with the old one."
