Atomized mist: The Nano Cool Mist humidifier uses ultrasonic technology to atomize the water molecules into super small particles so that the ultra-fine mist can be more easily absorbed and e.g. counteract dry skin and mucous membranes in dry air. Nice mood light: With warm white LED light and 2 different spray modes to best meet different needs. Very quiet operation: The humidifier has a noise level of only 10 dB. Low consumption and minimal noise make the humidifier perfect for sleeping, resting or reading.  Automatic shut-off: Thanks to the built-in water level sensor, the ultrasonic humidifier automatically shuts off when the water level is low. User-friendly design: The container holds a full 500 ml of water that lasts a long time. With two modes, intermittent spray mode (intervals) and continuous spray mode. Both the main motor and the water tank are removable and easy to clean and use. The humidifier is compatible with most USB power sources (5V low voltage input).  Change filters regularly: We recommend replacing your air filter after 2-3 months of use (depending on usage and water quality, in case of hard water you will need to change a little more often). Suitable filter (refill 10-pack): item no. HF-GX101-12 Specifications: Color: white Weight: 236 g Size: 12.9 / 9.5 / 9.5 cm IMPORTANT: 1. Soak the cotton swab for 3-5 minutes before first use. 2.
