Air pollution takes more than 7 Million lives globally every single year. Over 5% of premature children's deaths occur due to air pollution in developing countries. Everyone has relied on governments or experts to solve the problem, but most solutions up until today have either been too expensive or too ineffective. Praan is an attempt at making the future cleaner, healthier, and safer for the generations to come.
