MULTI- FUNCTIONAL AIR POLLUTION TREATMENT DEVICE

Abstract

This paper presents the design and development of a multifunctional air pollution treatment device capable of removing dust, odors, airborne pollutants, and bacteria, while also regulating air temperature seasonally—cooling in summer and heating in winter. The device integrates multiple air treatment technologies, including HEPA filtration for particulate removal, UV light for sterilization, activated carbon for pollutant removal, water mist for cooling, and air heating for winter. Experimental results show the system achieves a PM2.5 filtration efficiency of up to 99.97%, a bacterial sterilization efficiency of 95%, and a VOC removal efficiency of 90%, while effectively maintaining seasonal air temperature balance. With its versatile operation and high efficiency, this device has significant potential for real-world applications, particularly in households, offices, hospitals, and other enclosed environments.
