"Needed a second machine for travel. Bought a duplicate of what I had. This is my second machine. Could not find elsewhere for less. BUYER BEWARE--Make sure that if you buy form elsewhere that product is new."

"The M Series Heated Humidifier came in a bundle with my M Series flow generator. I'm very happy with this device. It is very different from the humidifiers that came with the non M Series machines.

Positive changes include the knob on top of the humidifier. This happens to be my favorite feature. The knob allows changes to the humidification very easily and even turning off humidification if desired.

The water tank is improved as well allowing very easy access for cleaning. It is a smaller tank than previous models but performance doesn't appear to be affected by this fact. The small door covering the slot for the tank is a nice feature also. The unit has a very clean and neat look.

The only cons I am concerned with revolve around the basic construction and the outlet. The previous model humidifier had a very sturdy construction and made up a base for the entire unit. This humidifier still acts as a unifying base, but it is not as heavy and protective. The instructions clearly state not to place on carpet or any other material that would have even a remote chance of being damaged by heat. This tells me that heat is transferred through the bottom of the machine more easily than previous models. This only requires something to set the unit on that can withstand the heat. Maybe a small wooden stand.

The outlet for the humidifier is at the rear. The location of the outlet of the flow generator itself is also in the rear, so this doesn't change the function of an M Series machine, I just don't like having the outlet in the back. This is a matter of preference and I hope to overcome this with a non-swivel elbow of some kind."
