The geometrical design of the system allows for a longer air-flow pathway inside the optical box to increase the exposure time. An electrostatic or ionizing structure, traps the bacteria and viruses and slows down their movement inside the mask, significantly increasing the light exposure time. In addition, the air can flow through thermal (heating or cooling) engines and sonic or ultrasonic exposure engines for increasing the whole system's effectiveness. The UV exposure unit, the electrostatic unit, the thermal unit, and the sonic/ultrasonic unit can be smartly activated or deactivated using an air flowmeter that significantly reduces the power consumption of the system and its generated heat. The flowmeter can also selectively control the power of each unit depends on the flow rate or flow direction of the air inside the system. ## Claims ### Claim 1 An air sterilizer system comprising of
