Optimized pressure delivery, no matter which mask is used.

System One Resistance Control achieves complete system comfort by enabling the device and mask to work optimally together. Through simple settings, the technology instructs the device to compensate for variable resistance characteristics related to different masks. The result is synchronous pressure delivery and the assurance patients can enjoy the full benefits of our Flex comfort technologies no matter which Philips Respironics mask is used.
