It uses ultrasonic technology to convert water into a fine mist of 1–5 µm particles, ensuring even distribution of moisture. The unit has a 5 L water tank, a rated power of 30 W and a humidification output ranging from 100 to 250 ml/h. A touch control panel with indicator LEDs and a 4-step intensity adjustment lets you set output to match room conditions. The device includes automatic shut-off when the water level is low, operates at a maximum noise level of 38 dB and can run up to 50 hours on a single fill. Cable length is 1.5 m and the appliance is supplied in white finish.

Advantages

The ultrasonic system produces very fine mist particles (1–5 µm) for effective humidification without raising surface wetness. Low energy consumption (30 W) and a large 5 L tank reduce refill frequency and operating costs. The touch panel with LED indicators and 4-step intensity control provides simple, precise adjustment of humidity output. Built-in automatic shut-off enhances safety and prevents dry operation. With a maximum noise level of 38 dB, the unit is suitable for bedroom and office use where quiet performance is required.

Suitable for

• Living rooms and bedrooms to maintain comfortable indoor humidity
• Nurseries and children's rooms where low noise is important
• Small offices and workspaces requiring stable humidity

How to use

Place the humidifier on a flat, stable surface away from direct sunlight and heat sources. Fill the 5 L tank with clean water and securely close the tank according to the user instructions. Use the touch panel to select one of the four intensity levels; the LED indicators will show the chosen setting. The unit will produce a cool mist that disperses into the room; adjust the intensity based on room size and current humidity. The humidifier will automatically switch off when the water level is low. Unplug the device before cleaning or refilling.

Usage recommendations

For best results, use clean tap or filtered water and perform regular cleaning to prevent scale or mineral buildup. Place the humidifier at least 30 cm from walls and furniture to avoid moisture accumulation on surfaces. Operate on lower intensity during night-time for quieter performance and extended running time. Follow the manufacturer’s maintenance instructions to preserve efficiency and warranty coverage.
