The resistance of a new air filter is called the initial resistance. As more particles are absorbed, the resistance increases. This leads to higher wind resistance, greater wind pressure loss, reduced wind speed and airflow, and increased fan power consumption, which is not conducive to energy conservation. To maintain or reduce the increase in wind resistance, it is necessary to frequently replace or clean the air conditioner filter, which increases maintenance costs. During the daily operation of the air conditioner, air humidity can also contribute to wind resistance. When humidity rises, dust particles on the filter material can clump together, further blocking airflow.
