  Abstract

The purpose of this study was to develop a filter and automatic power supply (APS) to remove volatile organic compounds (VOCs). Copper, lead, and aluminum were used as filter materials for the VOCs. However, lead poses potential health risks when exposed to the human body, and aluminum was not used because it does not effectively remove harmful substances when exposed to ultraviolet rays. Therefore, copper was selected as the final material for this study. The test results showed that Nano-TiO2 had a porous structure and effectively removed a significant amount of harmful gases without ultraviolet A (UV-A) irradiation. The removal of harmful gases, such as formaldehyde, increased by 85.9% upon irradiation. To design the power supply, an equation was derived to calculate the maximum power consumption per hour of the exhaust/intake system, various sensors, and safety devices used to purify harmful gases. Based on this equation, the discharge rate was measured after 48 hours. The developed APS retained 25% of the energy after 48 hours. Additionally, it met the standards set by the Institute of Electrical and Electronics Engineers (IEEE) and International Electrotechnical Commission (IEC) standards for Total Harmonic Distortion.
