The REMstar passover humidifier is a universal passover humidifier with a 24-inch "short tube" that's compatible with all CPAP machines. Both ports on the humidifier are standard size 22mm ports that are compatible with all standard CPAP tubing.
Capacity is approximatley 600 ml. Dimension are approximately 11" x 8.5" x 2". The small air inlet and outlet ports stick up an additional 1.25" from the top surface of the humidifier, making the height 3.25" instead of 2" when measuring the height including the air outlet ports.
The REMstar universal humidifier features latches that lock into place and a gasket that seals the perimeter of the lid. The humidifier can be opened for easy cleaning. Rubber feet on the bottom of the humidifier help keep the device secure on your night stand, even if your CPAP machine has been removed (i.e. when there's no weight on the humidifier).
Filling the humidifier is easy, too. Just close and lock the humidifier, turn the humidifier vertical so the letters on the front are readable, and then pour water into the air inlet port until water reaches the clearly marked fill line.
The REMstar passover humidifier is suitable for use with just about any CPAP machine, including older, bigger CPAP machines as well as newer smaller CPAP machines. The humidifier is designed so that the CPAP machine sits right on top of the humidifier.
Our Transcend II CPAP machine is an excellent example of a newer CPAP machine with no "built-in" humidifier option. This universal humidifier is a great option for Transcend users looking to add humidity to their CPAP therapy.
