Every up has a down. Let’s get down to the downside of sleeping with a humidifier every night.

While you can observe the water levels get to dangerous level during the day, you won’t   do so while sleeping. However, you can mitigate this risk by ensuring that you choose a room humidifier whose continuous mist production is longer than the number of hours you sleep.

Also make sure that the humidifier has an auto shut off sensor which shuts down the unit when the tank runs dry.

A Filter-less humidifier produces white / gray dust along with the much needed mist.  This white dust is the minerals present in regular tap water.
