It's 7:00 AM in New Delhi. The sun struggles to pierce through a dense gray haze, and the air smells of burning metal. Aarav, a bright-eyed 9-year-old, stares out of his apartment window. Instead of bustling streets and playing with children, he sees a ghostly, muted world. His mother hands him an inhaler. Another day, another battle to breathe.In a country where over 1.67 million people died from air pollution-related causes in 2021 alone, Aarav's story is tragically common. The invisible enemy lurking in India's atmosphere affects rich and poor alike, but access to clean air remains a luxury few can afford. What if I told you that a simple, low-cost innovation—a box fan and some filters—could offer hope? A jaw-dropping twist that might change how India fights air pollution forever.
