How long does one fill last?

The rated run time is up to 40 hours, which assumes the lowest mist setting. Expect noticeably less on high output or in a dry room.

Does it shut off when the water runs out?

It has no humidity sensor or auto mode. Check the water level yourself rather than relying on the unit to stop at a set humidity.

Tap water works, but minerals in hard water can leave white dust on furniture. Distilled water avoids that and cuts cleaning.

Rinse the tank and wipe the base every few days, and do a deeper clean weekly. Standing water in a warm room builds film and odor fast.

It suits a bedroom or small living room. For a large open-plan space, expect to run it high and refill more often.

Ultrasonic misting is quiet at low output. On high settings you will hear more gurgling and fan noise, which some light sleepers notice.
