Estonian tech firm creates wearable air purifier

Estonian tech company Respiray has launched a wearable air purifier

that uses ultraviolet light to kill viruses and bacteria in the air inhaled by its wearer

(SOUNDBITE) (English) RESPIRAY CO-FOUNDER, ROBERT ARUS, SAYING: “It sucks in air from the bottom part where there is an intake filter to remove larger dust particles. And after that, the air is led through our patented pending disinfection modules, which inactivate various viruses and bacteria. And after it blows air towards your face at a maximum speed of 55 liters per minute."

The company said tests of the device at the University of Lodz in Poland

achieved reductions of over 99% against E.coli and S.aureus bacteria

(SOUNDBITE) (English) RESPIRAY CO-FOUNDER, ROBERT ARUS, SAYING: "This is a non-medical device, as this is not meant for, like, let's say a doctor to wear. But in an environment where the concentration of viruses or potential danger is not that high, I think yes, this device can replace regular face masks."

Retailers and the Estonian education ministry have placed orders

with deliveries due to start in March

The device retails for around $340
