Abstract: An HVAC system includes one or more air quality sensors, each configured to measure an air quality and a thermostat communicatively coupled to the one or more air quality sensors. The thermostat receives indoor air quality measurements from the one or more air quality sensors. An indoor air quality score is determined based at least in part on the received indoor air quality measurements. The thermostat determines, based at least in part on the indoor air quality score, a mitigation action, wherein the mitigation action comprises one or more actions selected from the group of: (i) a filtering action comprising filtering air provided to the space using an air purification subsystem, and (ii) a ventilation action comprising ventilating the space using a ventilation subsystem. The mitigation action is executed, or implemented, by adjusting one or more components of the HVAC system.
