IIT-Delhi startup came up with cost effective respiratory filter

Just days before the toxic Delhi smog problem arises, an IIT- Delhi startup came up with a new idea of a respiratory filter. The respiratory device is called “nasofilter” that will cover your nostrils and will be available at a price of Rs.10 per filter. One filter will work for 7-8 hours. They are planning for a pan India launch on December 2 and the makers are hoping to provide the pollution stricken people some relief.
