1. The working principle of wet film humidifier

Wet film humidifier (also known as evaporative humidifier) is a kind of equipment that uses the principle of water evaporation to increase the humidity of air. Its core component is the wet film (usually made of plant fibre, glass fibre or metal materials), the working principle is as follows:

Water circulation system: the water pump transports water to the top of the wet film, so that the water is evenly distributed and flows downwards along the surface of the wet film.

Air flow: Dry air is drawn in through the fan, and when it passes through the humidified wet film, the water naturally evaporates into the air, thus increasing humidity.

Filtration and purification: The wet film can also adsorb dust and particles in the air during the humidification process, playing a certain role in air purification.

Since the wet film humidifier does not produce water mist or white powder, it is suitable for places with high air quality requirements, such as offices, data centres, hospitals, laboratories and so on.

3. Advantages of wet film humidifier

(1) energy saving and environmental protection

Wet film humidifier only relies on the natural evaporation of water, without heating or high-frequency vibration, power consumption is much lower than electric and ultrasonic humidifier, long-term use can significantly reduce energy costs.

(2) No white powder pollution

Ultrasonic humidifier if the use of ordinary tap water, may precipitate calcium and magnesium ions to form ‘white powder’, while the wet film humidifier only through evaporation humidification, will not produce such problems.

(3) Air purification

Wet film in the humidification process can adsorb dust and particles in the air, improve air quality, especially suitable for high cleanliness requirements of the environment.

(4) Low maintenance cost

Wet film humidifier structure is simple, low failure rate, only need to regularly clean the wet film and water tank, low maintenance costs.

(5) Wide applicability

Applicable to office space, data centres, greenhouses, textile factories, electronic workshops and other environments, especially suitable for scenes that require stable humidity but should not have excessive water mist.

4. Conclusion

Wet film humidifier has become an ideal choice in modern humidification technology by virtue of its energy-saving, non-polluting, low-maintenance advantages. Compared with ultrasonic and electric humidifiers, it is more economical and healthier in long-term use, especially suitable for application scenarios that are sensitive to air quality and energy consumption. In the future, as the demand for energy saving and environmental protection rises, wet film humidification technology is expected to be widely used in more fields.
