Wilfa Lotus HU4-4W Steam Humidifier - White

The Wilfa Lotus HU4-4W Humidifier – White is a steam humidifier designed for rooms up to 30 m². It outputs moisture at a rate of 200 ml per hour to increase ambient humidity. Proper dispersion requires placement approximately one metre above the floor. The unit uses a heating element to generate steam, and a standard mains connection supplies the necessary power.

Construction consists of a white plastic housing intended for flat surfaces. A built-in water level indicator shows when the reservoir needs refilling. An indicator light provides basic operating status feedback. This model lacks a programmable timer, a dedicated sleep mode, and smartphone remote support, relying entirely on manual operation. The absence of air purification or ioniser capabilities means the unit focuses strictly on adding humidity.
