This item has been discontinued by the manufacturer and is no longer available. It is listed here for reference only.
One replacement chamber for all Respironics "Legacy" REMstar and H2 Heated Humidifiers. Includes two replacement couplers to attach the chamber to the machine. These are for the older original REMstar machines, hence the "Legacy" designation that look like the machine pictured here.
They will not fit the newer Sleepeasy, M-Series, or PR System One machines.
** NOTE - This is the new design chamber with anti-backflow valve to prevent water from backing up into your machine.
