Abstract
An air filtration and exhaust system is described. The system comprises a microcontroller, a power supply, and a series of sensors that detect the presence of airborne contaminants such as ultra fine particles, smoke, natural gas and radon gas. In the presence of these airborne contaminants, the system is designed to inactivate and prevent operation of nearby food preparation appliances. Once these contaminants have been safely removed, the operation of these appliances is restored. In addition, the ventilation system may be equipped with a purification subassembly, which safely and efficiently removes such containments from the area. The system may also comprise an alarm that is activatable in the presence of these contaminants.
