Hard to tell, but the machine is lightweight, and barely takes up the surface of a small nightstand.

Not sure if you can see it --maybe zoom in w/computer--but this machine has a humidifier, so if the air coming into my mask feels too dry, I just fill the right side with distilled water, and turn the circular dial on top, which has different levels of cooling the water. This helps me immeasurably.

Also you may notice the tubing attached--it's not giant, and it's very mobile.
