Development of a UV-LED air purifier for indoor air

Indoor air is contaminated by a variety of chemical and microbial contaminants. These contaminants can be effectively removed or inactivated using a process known as photocatalysis. In this method, a photocatalyst is chemically activated using ultraviolet (UV) radiation and readily degrade the contaminants when coming in contact with them. The application of newly emerged ultraviolet light-emitting diodes (UV-LEDs) as the radiation source for photocatalytic air purification is investigated in this project. A UV-LED-based air purifier concept is developed, and the engineering design is optimized using simulation tools. Then, a prototype with an optimal design is fabricated and is experimentally tested for removing several chemical and microbial contaminants. The outcome of this work is important for improving the indoor air quality by removing chemical and microbial pollutants in the air.
