This is a college course project in an effort to understand the design process that is followed to design any product for general consumers. The topic selected for the project was the redesign of an air purifier for the Indian middle-income group. The concise brief can be quoted as “To design a range of air purifiers for middle-income groups, keeping in mind usability, serviceability, portability, ergonomics, aesthetics, interface or navigation, and visual semantics as features." The issues targeted were selected based on interviews that were conducted during the project. Air quality is deteriorating around the globe rapidly, and to mitigate that problem for metropolitan cities, an air purifier remains the only solution. As a necessity, that product becomes an integral part of our lives. Following the design principles of Dieter Rams, who said, "Good design is often invisible," the goal is to make the product with the best possible interaction for the user to make it invisible.
