- Is the Classic 100 worth it?
- Yes, if you need a quiet humidifier for one bedroom or nursery and do not want smart features. At $25.00 at eBay as of November 3, 2026, it is a low-cost way to add cool mist to a small room.
- How big a room will it humidify?
- Levoit rates it for roughly 107 to 290 sq ft, which is a bedroom, office or nursery. It is not a whole-house unit, so open-plan spaces will not see much change.
- How often do I refill the tank?
- The tank holds 2.4 L and the unit puts out up to 250 ml/h. At full speed expect to refill roughly every 8 to 9 hours; on low it lasts longer.
- Does it work with tap water?
- It can, but hard tap water can leave white mineral dust on surfaces. Distilled water avoids that and is the safer choice for the ultrasonic plate.
- Does it have a timer and auto shutoff?
- Yes. It has a timer, adjustable humidity control and automatic shutoff when the water runs out. There is no app or Wi-Fi control.
- When is it cheapest?
- Small humidifiers like this drop most in fall and winter sales and around Prime Day-style events. The current $25.00 at eBay as of November 3, 2026 is already near the bottom of its usual range.
