Luna II 3B Auto CPAP machine.

This is my 3rd CPAP in 18 years and is by far the quietest and most effective machine I ever had. I get a much better nights sleep. My recent readings showed I never stopped breathing during a 2 week study.

3B Luna ll AutoCPAP

This is my fourth CPAP machine, and I am very satisfied with this new unit I purchased two weeks ago. It is quiet and I have sleeping through the whole night without interruptions.
