| Summary, etc. |
Air pollution is a global problem that continuously worsens as time passes.<br/>Unfortunately, it contributes significantly to various respiratory diseases and deaths<br/>around the world. To address this, many studies have shown that air purifiers can<br/>effectively improve air quality conditions. However, there is still a lack of research on<br/>their cost- effectiveness and use of sustainable materials. Therefore, this project study<br/>aimed to design, develop, test, and evaluate an air purifying system using both<br/>conventional and solar energy sources and locally available organic filters such as<br/>coconut husks and carbonized rice hull. The prototype was tested in a controlled room<br/>with an initial air quality measurements of 4.36 parts-per-million (ppm) TVOC,<br/>0.11ppm HCHO, and 29.1 PM10. After conducting series of tests, test results show that<br/>HCHO decreased from 0.11 to 0.09 ppm, and PM10 with a decrease from 29.1<br/>micrograms per cubic meter (μ g/m3<br/><br/>) to 22.1μ g/m3<br/><br/>. The results imply that the system<br/>is effective in reducing air contaminants. Moreover, thirty respondents, composed of<br/>industry experts and engineering students, evaluated the prototype and rated it as very<br/>acceptable (x̅=4.47), signifying that the system is functional, workable, durable, safe,<br/>aesthetic and economical. The primary beneficiaries of the project are the people<br/>working in an enclosed room with poor ventilation, and people with allergies, asthma<br/>and other respiratory diseases. The outcome of this project study aims to contribute to<br/>the United Nations Sustainable Development Goals 3 and 7, promoting good health and<br/>ensuring access to sustainable energy. |
