Frequently asked questions

How long does the 220ml tank last per fill?
Runtime varies with mist setting and room conditions. Expect roughly four to six hours of continuous mist on a single fill. Use distilled water for the cleanest output.

Can I leave it running overnight?
The unit is designed for short, focused runs. Many users run it during sleep on a low setting; just make sure the tank has water and the unit sits on a flat, water-safe surface.

Will it leak if I tip it over?
Keep it upright. Tipping any USB humidifier can spill water through the air vent and damage the internal fan. Place it on a stable, level surface.

What water should I use?
Distilled or filtered water is best because it leaves less mineral buildup. Tap water works in a pinch; just clean the tank more often to prevent residue.
