- How long does one fill last?
- About 8 hours on a lower setting. Higher fan speeds drain the 0.2-gallon tank faster.
- Does it shut off by itself?
- Yes. It stops automatically when the tank runs dry, which matters for nursery use.
- What size room is it for?
- Small spaces such as a nursery, bedroom or office. It is not meant for large open rooms.
- Is it a warm or cool mist humidifier?
- Cool mist only. There is no warm mist setting.
- How often should I clean it?
- Rinse the tank and wipe the base regularly, and descale when you see mineral buildup. Ultrasonic units need this more often with hard water.
- Does it need a filter?
- No filter is required. That keeps upkeep simple compared with evaporative humidifiers.
- Where is the Crane Ultrasonic Cool Mist Humidifier EE-5951 cheapest?
- At Campingworld, for $49.99, as of our latest check.
