Verdict

The TROTEC B 5 E is a 2-in-1 ultrasonic humidifier and air purifier designed for rooms up to 30 m² (75 m³), operating with a 4-litre water tank and a low power consumption of 25 W to 32.7 W. It delivers a maximum humidification performance of 7.2 litres per day, offering up to 13 hours of continuous operation using standard tap water. Main characteristics and pros include a 360-degree rotating mist nozzle, a built-in ioniser to enhance air quality, three adjustable mist intensity levels, touch controls with a digital humidity display, and integrated smart functions like automatic operation, baby/night modes, a timer, and switchable LED tank lighting. However, a potential con is that the continuous fine mist can cause localized water condensation on nearby moisture-sensitive objects if not placed carefully, and regular manual maintenance is required to wash the air filter and prevent microbial growth in the tank.
