- How long does the tank last?
- At low output it can run through a night; on high it typically empties in well under a day. Expect to refill most days in continuous use.
- Is it safe for a baby's room?
- It is BPA-free, cool-mist only, and shuts off automatically when empty, which suits a nursery. Keep it out of reach and clean the tank regularly.
- Does it need distilled water?
- Distilled or filtered water reduces the white mineral dust that ultrasonic humidifiers can leave. Tap water works but may coat surfaces and the unit.
- How often should I clean it?
- Rinse the tank and wipe the base every few days, and descale weekly with a vinegar solution. Standing water in a warm room encourages buildup.
- Does it have a humidistat or timer?
- No. It has no built-in humidistat, timer or warm-mist setting, so you control output manually and switch it off yourself.
- What rooms does it suit?
- It is best for a bedroom, nursery or small office. The 480-square-foot rating is generous for a 0.5-gallon tank; expect it to serve one modest room.
