TrueBlue™ CPAP Mask Cushion and Flap by Philips Respironics
The TrueBlue™ CPAP Mask Cushions ensure you get the maximized seal intended by allowing the purchase of multiple size options.
The Premium Blue Gel works in conjuction with the thin and form fitting outer silicone seal creating a self adjusting seal which has been proven to be extremely effective and comfortable! The silicone seal or silicone membrane has a free form spring that allows you to move in any direction and keep your perfect fit. Due to this ability for movement, you can achieve a better night of sleep because of less disturbance from the leak of a cushion.
