The past few days have seen a high level of pollution across Delhi. A gray haze has settled across the city. The smoky, acrid air is harmful to all making it difficult to breathe. To highlight this public issue, Hike Messenger has introduced a face filter with the pollution mask. So get on Hike, click your pic and share it on Stories and Timeline on @Hikeappand facebook.com/hikeapp. Add your voice to #LetDelhiBreathe as we believe filters are best enjoyed only in-app and not in real life.
