- Is this humidifier good for a bedroom?
- Yes. Ultrasonic mist is quiet and the 30 W draw is low, so it suits a bedroom. Its output is best for one room rather than a whole floor.
- Does it shut off when the water runs out?
- Yes. It has automatic shutdown, so the unit stops when the tank is empty. That protects the transducer from running dry.
- Can I use tap water in it?
- You can, but hard water leaves white mineral dust on surfaces and can build up on the transducer. Distilled water keeps the mist cleaner and the unit easier to maintain.
- Does it have a humidistat or timer?
- No. You set the mist level by hand and switch it off yourself. Rivals in this class often add a humidistat, timer or remote.
- How often do I need to refill the tank?
- The 1.32-gallon tank lasts roughly a day or more at low output and less at high output. Expect to refill every day or two in continuous use.
- How much maintenance does it need?
- Plan to rinse the tank and wipe the base every few days and to descale monthly. Ultrasonic units build up mineral film if cleaning is skipped.
