Meet 2 Delhi Teens Who Turn Classroom Fans Into Rs 140 Air Purifiers

Two Delhi teenagers have found a way to turn an ordinary classroom fan into an air purifier for Rs 140. Their tests suggest it can sharply cut fine-particle pollution.

They say thousands of students are already using the filters. But the hardest part was still ahead: convincing schools to give them a chance."Schools are understandably skeptical of new technology being presented by high schoolers," Krish Aggarwal and Samarth Meattle told NDTV.

"Our biggest hurdle today is getting approvals and cutting through bureaucracy."Krish, a Class 12 student at Sanskriti School, and Samarth, a Class 11 student at Vasant Valley School, are the founders of Project Vayu. Krish has been named to the 2026 Diana Award Roll of Honour for the initiative.The idea came from growing up in a city where toxic air has become a winter reality."What bothered us was that some schools can buy air purifiers and thousands of students in under-resourced schools just sit in the same air all day with nothing.
