Beschreibung
Zusammenfassung:	Systems and methods for monitoring the status of air filters are provided. One or more thermoelectric sensors are provided to have an upstream sensing surface positioned adjacent the inlet surface of the air filter, and a downstream sensing surface positioned adjacent the outlet surface of the air filter. Sensing circuitry are connected to the thermoelectric sensors, configured to receive signals from the thermoelectric sensors and process the signals to obtain status information of the air filter.
