Airinum in Stockholm, Sweden is a successful company that offers an anti-pollution breathing mask
to poor air quality, one of the world’s largest indirect health risks according to the World Health
Organization . The company has also been boosted by the ongoing COVID-19 pandemic and the
global demand for breathing masks.
The key to the protection is five layers of protection, each layer with different density in order to
filter particles of different sizes. The technology is tested at the RISE R&D center in Sweden, one of
the world’s most advanced filter laboratories.
