FITS RESMED AIRFIT F40 FULL FACE MASK: Direct replacement headgear for the AirFit F40. Same connection system as the original ResMed strap. If your F40 headgear has stretched or lost its hold, this restores the fit your mask needs for a proper seal. Available in Small, Standard, and Large. SAVE VS OEM REPLACEMENT: ResMed F40 headgear through your DME or medical supplier costs significantly more. Same quality strap at a better price. FSA and HSA eligible as a CPAP supply. F40 HEADGEAR IS NOT INTERCHANGEABLE: The F40 uses a different headgear design than the F20 or F30. Do not order F20 headgear for an F40 mask. Check the model name on your mask frame to confirm you have an F40 before ordering. REPLACE EVERY 6 MONTHS: Even if the F40 is relatively new to your rotation, headgear elastic degrades with nightly use, washing, and body oils. Once you start overtightening to stop leaks, the headgear is the problem. Fresh straps = better seal, less skin irritation, more comfortable sleep. QUICK CLIP INSTALLATION: Attaches to the F40 frame in under a minute. No tools, no modifications. Match your headgear size to your F40 cushion size. For added comfort, pair with resplabs strap covers or the cpaphat headgear liner.
