This research paper examines the effects of air purifiers on air quality and filter performance. Air pollution is a major problem in many parts of the world, and outdoor air quality is no exception. Many people spend a significant amount of time indoors, making it essential to have clean air to breathe. Air purifiers have become increasingly popular as a means of improving outdoor quality. This study investigated the effectiveness of air purifiers in removing air pollutants, such as particulate matter, volatile organic compounds, and allergens. Additionally the paper examines the performance of air filters in trapping pollutants and extending the life of the air purifier Growing industrialization in urban areas is leading to increased air pollution, with contaminants such as industrial dust, smog, and traffic-related particles affecting the quality of the air we breathe. To address this issue, individuals can opt for air purifiers to clean the air inside their homes. However, many air purifiers available today use filters that contribute to waste and ultimately end up in landfills. This not only contributes to poor outdoor air quality but also leads to a smaller filter supply and higher costs for consumers on a daily basis. This project focuses on designing and developing a novel outdoor air purifier that incorporates principles of human design and eco-design. It employs various methods commonly utilized in the design process to ensure a reliable and user-centered outcome that meets the needs of the users. The project also led to the creation of a patented filter design that allows consumers to clean it themselves, removing the need to purchase new filters. Moreover, this filter consumes less energy and has a smaller, more compact size compared to its market competitors. As a result, it minimizes material usage, ultimately reducing the negative environmental impact.
