NEW in Box RESMED Air Sense 10 CPAP Machine Water Tank

This is NEW in the BOX. My husband bought 2 of these to have as extras for his CPAP machine and has not even taken them out of the boxes. His CPAP died and is getting a different one which does not use this size water holder. Item #37299 for the RESMED Air Sense 10 machine. We paid $30.00 NEW for them.
