Yes. It uses magnetic headgear clips. 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.
