Excellent Product Hello, My wife has severe COPD. Having both the room and portable concentrators has been, both upstairs and downstairs, has been a necessity for several years now. The affordability and quality of Varon's units have helped with the quality of her remaining life. Our insurance did cover one unit with a $26.50 copay each month.
