Engineers develop pollution filter that can be jammed in the nostrils

Air pollution is among one of the major factors threatening severe health consequences for people in several parts of the world. As people struggle to breathe in several cities and governments introduce measures to improve air quality, many are trying to find ways to survive pollution.

Now engineers have developed a pollution filter that people can stick inside their nostrils and block 90 per cent large pollution and 70 per cent finer particles. The device is almost invisible and is being sold in the US in packs of 10.

The filter can be worn for 12 hours and captures air particles and more by using electrostatic filters. Such inventions are important when air pollution is having a devastating effect largely in cities of India and China.
