The role of the fan in the air purifier is not only to promote the flow of air, but also to improve the efficiency and effect of purification.

• Air circulation: The fan is responsible for pushing the air flow in the air purifier. Through the fan, the air is drawn into the purifier, which is processed by a filtration system before the clean air is discharged into the room. This process ensures that the air in the room is evenly circulated and purified.

• Improve purification efficiency: the wind speed and gas flow of the fan directly affect the working efficiency of the purifier. Stronger fans can speed up the flow of air, allowing more air to pass through the filter, thus improving purification efficiency. The fan speed can usually be adjusted to suit different air quality needs and environmental conditions.

• Optimized filtration: In air purifiers, filtration systems (such as HEPA filters, activated carbon filters, etc.) work by capturing pollutants in the air. The presence of a fan allows air to flow through the filter more quickly, thereby increasing the filter's effectiveness and longevity.

• Enhanced air distribution: The fan helps distribute clean air evenly throughout the room, avoiding the problem that the air purifier may cause when local areas are fresh and other areas are still dirty. This helps to improve the air quality throughout the room.

• Reduced downtime: The operation of the fan helps maintain air circulation, reducing the burden of the purifier when dealing with high pollution levels, allowing the purifier to work steadily for a longer period of time, extending the service life of the equipment.
