Product description

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 this humidifier quiet for bedroom use at night?

This humidifier runs quietly, but its high mist output is best for medium to large rooms. To prevent moisture buildup and minimize any slight operational sounds, place it away from your bed and nightstand.

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

Is the humidifier stable and rollable after filling?

Equipped with a sturdy base and 4 wheels, it offers stable mobility. Designed for hard, level floors; not recommended for carpets.
