DEVICE AND METHOD FOR MONITORING HVAC AIR FILTER

The present disclosure is directed to an air filter sensor system that can monitor a status of a filter and provide information to a remote system regarding the filter's status. The system can receive, by a computing server via one or more computer networks and from each of a plurality of sensor assemblies coupled to a corresponding plurality of air filters, information indicative of filter contamination levels respectively associated with each corresponding air filter of the plurality of air filters. Each of the respective filter contamination levels being provided by one sensor assembly of the plurality of sensor assemblies based at least in part on a difference in detected air pressure between first and second sides of the corresponding air filter. The system tracks the respective filter contamination levels over a first period of time and determines, by the computing server and based at least in part on the tracking of the respective filter contamination levels, a schedule for one or more maintenance events associated with a first air filter of the plurality of air filters.
