What is the orientation of the air conditioning filter?
1 Answers
Air filter products usually indicate the inlet and outlet. On the side of the filter, there is a small arrow indicating the direction of airflow. During installation, the top is generally the inlet, and the bottom is the outlet. More details are as follows: 1. Most air conditioning filters available on the market today have arrows on the side indicating direction. The most common indicators are 'air-flow' with an arrow, while another method uses 'UP' with an arrow. 2. These two indicators convey different meanings. 'Air-flow' with an arrow represents the direction of airflow, whereas 'UP' with an arrow indicates the installation direction is upward. In fact, the installation directions for these two types of air conditioning filters are opposite.
