Questions, answered
Will a humidifier disturb my sleep?
Ultrasonic models like the MistAire and 300S run near-silent. Evaporative models have an audible fan; some people find the hum doubles as white noise, others do not.
Should it run all night?
Yes, with auto shut-off as a backup. Models with humidity sensors will throttle down once the room hits target, so they sip water overnight.
Does the light bother sleep?
Pick a model with dimmable or switchable lights. The MistAire's night light can be turned off, and the 300S display dims.
