Abstract

An air quality control system adapted for use with an entryway for a room, includes a touchless door adapted for association with the room and a door sensor associated with the touchless door to determine whether the touchless door is open or closed. An air purifier selectively deactivates pathogens and pollutants in air flowing through the air purifier and an air quality sensor positioned near the touchless door measures at least one parameter, whereupon the air quality sensor selectively activates and deactivates the air purifier based on whether a threshold level of the at least one parameter is exceeded or not.

Abstract

A sterilization system adapted for use with a selectively enclosed space includes a conduit having an inlet adapted to draw air in from the enclosed space and an outlet adapted to exhaust air into the enclosed space. An ionizer is maintained in the conduit and in close proximity to the outlet and a UV-C lamp is maintained in the conduit. A blower having a blower vent is adapted to exhaust ambient air into the enclosed space and an air quality sensor is maintained in the conduit and in close proximity to the inlet to measure at least two parameters and selectively controls the ionizer, the UV-C lamp, and the blower based on whether threshold levels of the at least two parameters are exceeded or not.
