1. An air filter condition monitoring system for periodically or continuously monitoring the condition of a flexible air filter over the life of the air filter when air is flowing through the filter, the air filter condition monitoring system comprising:

  • (a) an air filter having a peripheral frame and an interior filtering region;

    (b) a fixed support structure for receiving the air filter and maintaining the perimeter of the filter frame in a generally fixed position while allowing the interior filtering region to flex in response to air flow through the filter; and

    (c) a force measuring device mounted on the downstream side of the filter adjacent the interior filtering region in a fixed position relative to the supporting structure, wherein as the interior filtering region flexes in response to air flow through the filter, the interior filtering region exerts a force on the force measuring device that increases with the degree of clogging of the filter.
