    Abstract: An air filtration apparatus includes an airflow powerhead assembly including a fan assembly and a vane assembly, a filter assembly, and a separator chamber housing inside of which the filter assembly is disposed. The separator chamber housing has a chamber inlet at a first axial side and a clean air outlet at a second axial side of the separator chamber housing opposite the first axial side. The filter assembly has a first axial end adjacent the chamber inlet and a second axial end adjacent the clean air outlet. The separator chamber housing includes at least one debris ejection slot extension configured to eject debris from an inner space of the separator chamber housing. The filter assembly includes a debris catch tray disposed at the second axial end, the debris catch tray having a debris ejection slot aligned with the at least one debris ejection slot extension.

    Abstract: An air quality monitoring and control method includes providing at least one sensor inside of an enclosure; providing an advisor module configured to receive data from the at least one sensor; providing at least one airflow control valve regulating air between inside and outside of the enclosure; and controlling, by the advisor module, the at least one airflow control valve based on the data received from the at least one sensor to control air quality within the enclosure. Alternatively, the method includes providing at least one sensor inside of the enclosure, the at least one sensor including a dust sensor; providing a stand-alone recirculation filtration device in the enclosure; providing an advisor module configured to receive data from the dust sensor; and controlling, by the advisor module, the stand-alone recirculation filtration device or an HVAC fan based on the data received from the dust sensor.
