Yes. It uses magnetic headgear clips, and magnets in the cushion. Masks with magnets are contraindicated for anyone who, or whose bed partner, has an implanted or metallic device affected by magnets, such as a pacemaker, ICD, neurostimulator, CSF shunt, insulin or infusion pump, aneurysm clip, metallic stent, heart valve, cochlear or ocular implant, or a metallic splinter in the eye. Keep the magnets at least 6 inches (150 mm) from any such device. If this applies to you or someone sleeping near you, use a magnet-free mask instead.
