- How long does one fill last?
- Expect a few hours of mist per fill, depending on the model and setting. The tank is small, so plan on refilling it once or twice during a workday.
- Can I use tap water?
- Tap water works but leaves mineral dust and scale. Distilled or filtered water keeps the mist cleaner and the unit running longer.
- Does it shut off by itself?
- Yes. It stops automatically when the water level drops too low, which protects the unit from running dry.
- Will it humidify a whole bedroom?
- No. It is a personal humidifier for the area right around it, roughly a desk or bedside. For a full room, look at a larger ultrasonic or evaporative unit with a bigger tank.
- Can I run it from a power bank or car?
- Most versions run from USB power, so a power bank, laptop or car adapter works. Check the connector on the version you buy.
- How often should I clean it?
- Rinse the tank and wipe the mist outlet every few days, and descale with a vinegar soak about once a month. Skipping this causes odors and weak mist.
