Delhi schoolchildren fashion budget air purifier from basic fan for 140 rupees

A homemade air purification solution developed by schoolchildren in Delhi has gained traction online, demonstrating how basic engineering principles and readily available materials can address air quality concerns at minimal cost. The device, assembled for approximately 140 rupees, transforms a conventional fan into a functional air purifier using affordable components.

The innovation comes as air pollution remains a persistent concern across India's metropolitan areas, particularly during winter months when air quality indices frequently reach hazardous levels. With commercial air purifiers ranging from several thousand to tens of thousands of rupees, budget-friendly alternatives have garnered interest among cost-conscious households.

The project exemplifies the growing trend of jugaad—India's traditional approach to frugal innovation—adapted for contemporary environmental challenges. The device's viral circulation on social media reflects public interest in accessible solutions to everyday problems, particularly among young innovators exploring practical applications of scientific concepts.

While the device's effectiveness compared to certified air purifiers remains unclear, the initiative highlights how basic engineering knowledge and creative problem-solving can contribute to addressing household air quality concerns. Similar low-cost environmental innovations have emerged across India as awareness of indoor and outdoor air pollution increases.
