This 260ml Ultrasonic USB Humidifier and Aromatherapy Diffuser is designed to improve comfort in small spaces such as bedrooms, offices and cars. Built from durable PP and ABS plastics with a soft-touch silicone seal, it uses ultrasonic technology to create a fine, cool mist at approximately 40 ml/h. The 200 ml water tank offers up to 5-10 hours of continuous use, while the low-noise operation (under 36 dB) keeps it discreet in work or sleep environments.
