Highlights:

  • Nano-respiratory filter involving a cost of Rs. 10
  • Nasofilters is capable of restricting up to 95 % of dust and air pollutants.
  • It is ready for commercialization
  • The device provides protection against the finest particulate pollutants that are present in the air
  • It gives protection for up to eight hours and reduces the risk of respiratory diseases
  • The filter will main good breathability and comfort
  • The filter protects the people from air pollution and allergies
  • The device will turn out to be a great benefit for industrial workers.
  • The device will restrict the entry of foreign particulate matter that includes PM 2.5 particles, bacteria and pollen allergens
  • The device will restrict the entry of foreign particulate matter that includes PM 2.5 particles, bacteria and pollen allergens
  • These particles are released from vehicles, particularly those with diesel engines, industries, as well as from natural sources.
  • The researchers involved in the project were recently awarded with the “National Startups Award” by President Pranab Mukherjee.

How the Device Was Made:

  • The project to develop the filter involved assembling millions of small – sized pores to create a thin flexible membrane.
  • The membrane could capture very small particles with high efficiency
  • It allows filters to be used for long hours while maintaining good breathability and comfort
