The Philips Respironics Deluxe Chin Strap is designed with a wider coverage area when strapping around the chin and top of the head. The wider strap can help a user with keeping the chin strap on as it makes a greater contact with the general area of the head and chin. Philips Respironics Deluxe Chin Strap is an alternative for the user that has a tendency to breath out of the mouth while using a CPAP. The machine provides a positive airway pressure and at time, can cause a user to use their mouth when breathing. This will help in keeping the mouth closed.
