- Is it quiet enough for a bedroom?
- Yes. It uses ultrasonic vibration rather than a fan, so the mist is near-silent. Most owners run it overnight without complaint.
- How long does one fill last?
- Runtime depends on the mist setting. On low output it covers a night; on high output expect to refill sooner. It is best for small rooms.
- Can I use it as a humidifier?
- It adds some moisture to a small room, but the tank is small. For a large room or dry winters, a dedicated humidifier with a bigger tank works better.
- Does it need distilled water?
- Tap water works, but distilled or filtered water reduces mineral buildup and white dust. Clean the tank regularly either way.
- Does it have a timer or auto shut-off?
- It has simple controls rather than programmable timers. It stops misting when the water runs low, but check the manual for the exact behavior.
- What comes in the box?
- The diffuser unit, a power adapter and a measuring cup for filling. Essential oils are not included.
