Asia is one of the regions of the world that is most impacted by atmospheric pollution, with five countries that are hit particularly hard: China, India, Pakistan, Indonesia and Bangladesh. Close-up on three start-ups that have joined the fight against this phenomenon.
The Nasofilter anti-particle nose filter
According to a recent survey, seven of the ten most polluted cities in the world are in India. A worrying situation, in terms of both health and the environment. Following this observation, a team from the Indian Institute of Technology has developed a nasal respiratory filter that filters out air pollution, right down to fine particles. The filter is inserted directly in the nostrils, offering an alternative to conventional respiratory masks. Made of recyclable materials, the filter prevents 90% of fine particles from being absorbed. And it can last for up to 12 hours.
