Abstract
Systems and methods are provided for predicting failure of an air filter within an HVAC installation. Also provided are methods for calibrating the systems described. The system provided typically includes air filters and vents, and a processor at an application server configured to implement methods described. Each vent may include various sensors, such as a temperature sensor or a sensor for evaluating indoor air quality. The method may receive information about a total volume of air pumped by an HVAC system over time, determine the volumetric quantity of air passing through a particular filter, and compare that quantity of air to a threshold amount representing the lifetime, or some percentage of the lifetime of the filter. Where the system includes multiple vents and multiple filters, the system may implement a model for calculating the volumetric quantity of air associated with each individual filter.
