Entrepreneur Ankit Agarwal tackles India's air crisis by creating an affordable purifier that turns collected pollutants into sustainable tiles, offering a dual solution to environmental challenges.
In a world where air pollution is becoming an increasingly pressing public health issue, innovative solutions are desperately needed. One such solution comes from India, where entrepreneur Ankit Agarwal has developed an affordable air purifier that not only cleans the air but also repurposes the waste collected into useful building materials like tiles.
Air pollution is a silent killer. According to the World Health Organization (WHO), it is responsible for approximately 7 million premature deaths annually, with low- and middle-income countries bearing the brunt of this burden. In India, air quality in many cities often exceeds safe levels, leading to respiratory diseases, cardiovascular problems, and other health issues.
Ankit Agarwal, a passionate environmentalist and entrepreneur, saw an opportunity to address this crisis with a practical and sustainable solution. He founded the company "Greener Solutions" and developed a low-cost air purifier that can be used in homes and public spaces. The device is designed to be user-friendly and accessible, making it a viable option for communities that are most affected by poor air quality.
The air purifier operates on a simple principle: it draws in polluted air, filters out harmful particles such as PM2.5 (fine particulate matter), and releases clean air back into the environment. What sets this device apart is its waste management system. Instead of discarding the collected pollutants, which can be toxic if not disposed of properly, the purifier stores them for recycling.

The waste collected by the air purifiers is sent to a facility where it undergoes a process that transforms it into raw materials for making tiles. These tiles are durable and can be used in construction projects, thereby reducing the demand for new, resource-intensive materials. This innovative approach not only helps mitigate air pollution but also promotes circular economy practices.
The impact of this technology extends beyond just improving air quality. By providing a low-cost solution, Ankit's purifiers are making clean air more accessible to underserved communities. Moreover, the recycling process creates jobs and supports local economies, fostering a sense of community engagement and environmental stewardship.
While the initial results are promising, there are still challenges to overcome. Scaling up production and distribution to reach a broader audience will require significant investment and collaboration with government agencies and non-profit organizations. Additionally, ensuring that the recycling process is efficient and environmentally friendly is crucial for maintaining the sustainability of the project.
Ankit Agarwal's innovation is a testament to the power of creative thinking and community-driven solutions. As we face the growing threat of air pollution, it is essential to support and scale up such initiatives. By investing in clean technology and sustainable practices, we can create healthier environments for all.

About the author
Amara's entry point into AI was an epidemiology role at a London research hospital, where she spent five years studying how digital health tools reached — or conspicuously failed to reach — underserved communities. Watching early algorithmic systems in healthcare quietly entrench existing inequalities, she redirected her career toward the systemic consequences of AI at scale. She covers AI through an unflinching lens: who benefits, who bears the cost, and what evidence actually says versus what the press release claims. Her writing is calm and precise, but she doesn't mistake balance for neutrality.
