Masks containing magnets from the manufacturer ResMed

Sleep apnea device manufacturer ResMed announced on November 21, 2023 that it was updating existing contraindications and warnings regarding its masks that contain magnetic harness clips.

In response to new information from the latest industry practices and global safety data, ResMed updates contraindications and warnings in its user guides to educate patients on the safe use of masks ResMed equipped with magnets.


These masks are used to deliver air to a patient from a continuous positive airway pressure machine, commonly called CPAP. Magnets are used in some ResMed masks to allow patients to easily attach and separate the headgear and rigid mask surround when putting on the mask. This can be particularly beneficial for disabled patients, especially those with dexterity or vision impairments.


The following ResMed masks contain magnets. If you do not use one of the masks identified below, this letter does not apply to you.

Facial mask AirFit F20, AirFit F20 for Her, AirTouch F20, AirTouch F20 for Her, AirFit F30, AirFit F30i
Nasal mask AirFit N10, AirFit N10 for Her, AirFit N20, AirFit N20 for Her, AirTouch N20, AirTouch N20 for Her
Non-ventilated mask AirFit F20 NV

Patients who have a contraindicated medical device or a medical device that may interfere with magnets or anyone in close physical contact with any of the affected products. Masks with magnetic components are contraindicated for patients when they, or anyone in close physical contact with the mask, have the following:

  • Active medical implants that interact with magnets (e.g., pacemakers, implantable cardioverter defibrillators [ICDs], neurostimulators, cerebrospinal fluid [CSF] shunts, insulin pumps/infusions).
  • Metallic implants/objects containing ferromagnetic material (e.g., aneurysm clamps/flow breakers, embolic coils, stents, valves, electrodes, implants intended to restore hearing or balance with implanted magnets, ocular implants , metal shards in the eye).

For people who are not affected by such devices, masks with magnets are safe and can continue to be used.
