Abstract

Aerial pollutants including dust, pollen, pet dander, volatile organic compounds (VOCs), and even harmful microbes can build up as a result of poor ventilation or insufficient air movement. In order to help maintain a healthy indoor environment, this study intends to build an air purifying system that may be installed in a room. The outcomes of our research showed how well the built-in air purifier improved indoor air quality. The microorganisms in the airflow were significantly decreased by the device. With an average CADR of 200 CFM, the Clean Air Delivery Rate (CADR) measurements showed a considerable decrease in particle concentration with time. It was discovered that the starting particle concentration affected the decrease in particle concentration. Depending on the particle size and the length of operation, the concentration was reduced by 80%, 90%, or more than what was present in the room or surrounding area. The results shown here demonstrate that the device’s used air purifier successfully reduces the amounts of germs in the airflow.
