New Delhi– Consumer goods company Unilever on Tuesday announced the acquisition of air purifying solutions company Blueair for an undisclosed sum.

“Blueair will be geared to help potentially billions of people rather than millions to create safer, healthier indoor environments as air pollution rises worldwide,” said Bengt Rittri, Founder, Blueair, in a statement.

According to a recent World Health Organisation (WHO) report, air pollution is now the world’s largest single environmental health risk that “Killed around seven million people in 2012 alone,” Rittri added.

Blueair will continue to operate under its existing brand name in all its markets, including India, Sweden, China, the US, Japan and South Korea.
