• Is My Machine Compatible? System One 50 & 60 Series Differences
  • BRANDING = 60 SERIES System One machines include the words "System One" in raised embossed lettering stamped on both the machine and (if included) the humidifier. 50 SERIES System One machines feature branding that is painted onto the unit and the words "System One" only appear on the humidifier.
  • COLOR = 60 SERIES System One machines feature charcoal gray panels and metallic silver side panels. 50 SERIES System One machines are dark gray with ivory colored side panels
  • MODEL NUMBERS = 60 SERIES System One machines include reference numbers on the base of the machine that end in 60. For instance 560P appears on the bottom of all 60 Series REMstar Auto machines. 50 SERIES System One machines include reference numbers on the base of the machine that end in 50. Therefore 550P, 450P, 150P, etc would all indicate 50 Series machines.
