At Philips Respironics, we designed Pico with a clear goal in mind – to create a truly appealing traditional nasal mask that makes minimal contact with the face and offers simplicity, comfort and seal. These qualities make it an ideal choice for new and existing OSA patients who want minimal disruptions to their lifestyle. Comes with three sizes of nasal cushion, to help you find the best fit, Small-Medium, Large and X-Large.
