DeLonghi UHX17 is a compact and efficient warm steam humidifier designed to improve indoor air quality by providing consistent and hygienic humidity levels suitable for small to medium-sized rooms up to approximately 60 m³. The device operates using MicroDrop technology which produces a gentle mist of sanitized warm steam at temperatures around 55–65 °C, effectively reducing airborne bacteria and allergens while ensuring a comfortable level of moisture in the environment. It features a 1.6 liter water tank that allows up to seven hours of continuous operation on a single fill, and delivers a humidification output of approximately 230 ml per hour, translating to around 5.5 liters per day. The humidifier is powered by a 200 W heating element, and it incorporates safety mechanisms including an automatic shut-off when the water level is low, a built-in thermostat, and overheat protection, making it safe for home use including in bedrooms and living areas.

The UHX17 also integrates an aromatherapy compartment where a few drops of essential oils can be added, allowing the released steam to carry a subtle fragrance throughout the room, combining both humidification and air freshness in one unit. The water tank is easily removable and washable, ensuring convenient refilling and cleaning while maintaining hygiene. A pre-filter is included to trap dust and larger particles, helping to protect the internal components and maintain optimal performance. The device is mechanically controlled, making it simple to operate without complex settings, and is relatively quiet during operation, with noise levels around 35 dB.

In terms of design, the DeLonghi UHX17 is compact and lightweight, measuring approximately 31 × 20.1 × 20.1 cm and weighing around 1.3 kg, making it portable and suitable for placement on tables, shelves, or bedside surfaces. Its sleek Italian design combines functionality and aesthetics, ensuring it blends well with modern interiors. The warm steam mechanism avoids the white mineral residue often associated with ultrasonic humidifiers, providing clean vapor that does not settle on furniture or floors. While the device lacks digital controls or automatic humidity regulation, it offers straightforward operation and effective humidification along with the added benefit of aromatherapy, making it an excellent choice for those seeking a hygienic, safe, and fragrant indoor environment without complex electronics. The combination of warm steam, aroma diffusion, quiet operation, compact design, and safety features makes the DeLonghi UHX17 a versatile and reliable option for maintaining comfortable and healthy indoor air quality.
