Abstract

The present invention relates to an air filter leak detection system for use in air circulation systems. The system comprises a control device, an actuator, and at least one sensor capable of measuring airflow velocity or air pressure. The control device periodically executes a computer program stored in its memory to activate the actuator to sequentially position the sensor at multiple locations across the filter surface to ensure full coverage. At each location, the sensor measures a leak detection parameter, which is compared by the control device against a threshold value which may be determined as an average of previously measured values. When a leak is identified based on the comparison, the system generates and transmits an alert to a user device, including the precise location of the leak. This system enables continuous, in-situ monitoring of filters, detecting both the occurrence and position of leaks without interrupting system operation.
