The Upsides to This CPAP Model: All new heated tube humidifier option puts this unit back on the same playing field as the ResMed and Fisher Paykel models. The most popularly prescribed CPAP brand by U.S. physicians, the Philips Respironics 50 and 60 series offer reliability, durability and comfort. CFLEX and AFLEX (pressure relief) come standard as well as full compliance reporting. Assembled in the U.S.
The Downside to This CPAP Model: The second most popular selling Auto CPAP machine, it’s difficult to find a bad thing to say about it. It is more of a box shaped unit so the travel case is not a sleek and streamlined as the S9 AutoSet. If you wish to use the heated tube option it requires a separate humidifier and power supply as opposed to other models where the same humidifier works with heated and non heated tubing.
