Estonian technology company Respiray launched a portable air purifier on Monday that can kill more than 99% of viruses and bacteria using ultraviolet light.
The device was developed jointly with universities in Estonia and Poland and is supported by the Estonian Ministry of Education, which will distribute it to school teachers, Reuters reported.
Indrek Raymond, deputy minister in the education ministry, said he saw Respiray air purifiers as an additional element in the COVID-19 toolkit, along with vaccines, drugs and social distancing.
“There is no magic wand against the virus, but a number of combined efforts are contributing to the exit from the pandemic,” Raymond said.
The company says its air purifier is based on the thermodynamics of breathing – most of the inhaled air comes from air currents that rise from the body’s surface – and the known disinfecting properties of UV light.
The device consists of a plastic box worn around the neck, with the possibility to attach a transparent helmet to the face. It is powered by a battery and the charge lasts about 8 hours.
The air first passes through a suction filter that removes dust and larger particles, and then passes through a UV-C LED module that kills viruses and bacteria before being blown to the user’s face, Respiray explains.
Tests at the University of Lodz in Poland have shown that the device removes up to 99.68% and 99.88% of E.coli and S.aureus bacteria, the company said.
A study at the University of Tartu, Estonia, has achieved 99.4% efficiency in neutralizing Alphavirus, which is similar in size and structure to SARS-CoV-2, the coronavirus that causes COVID-19, said Lian Viru, head of the University Center for Biosafety. .
“The remaining low concentration of viral particles is very unlikely to cause infection in the target organism,” Viru said.
Retailers in the country have already begun placing orders for the device for their customer service staff, with deliveries set to begin in March. The price of the device is 279 euros.
