Daikin has been collaborating with universities and public research institutes to demonstrate the effectiveness of this technology for highly virulent influenza viruses (A-type H5N1), weakly virulent influenza viruses (A-type H1N1), mouse norovirus, and toxins and bacterias that cause food poisoning.
From the latest study, Daikin has confirmed that Streamer technology inactivates more than 99.9% of coronavirus (SARS-CoV-2) after irradiating the viruses for three hours with Streamer Discharge. This demonstration shows the results of experiments using a device that generated Streamer discharge under test conditions and does not indicate the effectiveness of an actual Streamer product in use under actual conditions.
Study done by Daikin Industries, Ltd., in cooperation with Professor Shigeru Kyuwa, Department of Biomedical Science, Graduate School of Agriculture and Life Science, the University of Tokyo, and a group of research professors led by Professor Shigeru Morikawa, Department of Microbiology, Faculty of Veterinary Medicine, Okayama University of Science.
Study Method: The team conducted an experiment, wherein they irradiated the viruses for three hours with Streamer Discharge.
Streamer Technology: is a type of plasma discharge featuring an innovative air purification technology that stably generates “high-speed electrons,” a feat which had proven difficult up to that time. Its oxidative decomposition capability is much greater than that of conventional plasma discharge (glow discharge). Moreover, when combined with air components, these high-speed electrons have a capability for powerful oxidative decomposition, and this capability enables Streamer discharge to continuously remove odors, bacterias, and indoor air pollutants such as formaldehyde.
