Frequently Asked Questions

Q: Can I use essential oils directly in the water tank of this mini humidifier?

A: Yes! This USB mini humidifier is also designed as an aroma diffuser. Simply add a few drops of your favourite essential oil to the water tank along with clean water to enjoy a gentle, fragrant cool mist throughout your space.

Q: How long does the battery or water last on one fill?

A: The 220ml water tank provides up to 8 hours of continuous cool mist on a single fill. Since it is USB-powered (not battery-operated), simply plug it into any 5V USB port — such as a laptop, power bank, or USB wall adapter — for uninterrupted use.

Q: Is this humidifier safe to use in a car?

A: Absolutely. The leak-proof sealed water tank and compact size make it ideal for car use. Just plug it into your car's USB port or a USB car adapter. The low 2W power draw means it won't strain your car's power supply.

Q: How do I clean this portable humidifier?

A: For best results, empty and rinse the water tank with clean water after each use. Periodically wipe the interior with a soft damp cloth. Avoid submerging the base unit in water. Using distilled or filtered water will help minimise mineral build-up over time.
