How does auto humidity control work?

It has a upgraded humidistat. You set desired humidity (40%-90%) and the unit automatically adjusts mist output to maintain that level When humidity reaches your set point it slows down or stops; when it drops, it restarts – no manual tweaking needed

Can I use essential oils? Where to put oil?

Yes. There is a dedicated aroma box on the back. Add a few drops of essential oil onto a cotton pad and place it inside the box. The mist will carry the fragrance. Do NOT put oil directly into the water tank or base – that may damage the humidifier

Is it quiet for bedroom use at night?

Yes, it's an ultrasonic humidifier at 30-40dB – quieter than a library, sleep-safe. Clean regularly per manual to prevent scale & keep it quiet. 1-16H timer & constant humidity mode make it perfect overnight.

What happens when water runs out? Is it safe?

Very safe. The humidifier has an auto-shutoff feature. When the tank is empty it turns off automatically and sounds a waterless alarm. No dry burning, no overheating – safe for homes with babies pets or elderly. You can leave it running without worry

How long does 4.5Gal (17L) last? Is it heavy to move?

At 12 hours/day of medium mist it can last 3-4 days It has 4 smooth-rolling wheels on the bottom so you can easily move it from room to room even for pregnant women or seniors. Also includes an extension tube to direct mist higher and avoid wet floor
