The Ardesto USH-H-4B is an ultrasonic humidifier designed to maintain a comfortable atmosphere in rooms up to 30 m². Its 4 L water tank is easy to refill thanks to the top-fill design, and it provides a steady mist output of 280 ml/h to keep the air hydrated. You can manage the device using the LED display and touch sensors or the included remote control, allowing you to choose from three steam intensity modes and set a timer from 1 to 8 hours. To ensure the environment stays exactly how you like it, the built-in hygrostat lets you adjust the target humidity between 45% and 90%. The black plastic housing measures 33 cm in height and 18 cm in width, making it a compact tabletop addition that weighs only 1.1 kg. For those who enjoy a personalized ambiance, it features an integrated aroma oil container and a backlight that cycles through 7 LED colors. When it is time to sleep, the night mode dims the display and reduces noise to avoid distractions. The system also monitors its own water levels, providing a shortage indication and shutting off automatically when the tank is empty to ensure safe operation. With a power consumption of 25 W, this device is a practical choice for anyone looking to regulate indoor humidity with minimal effort.
