Daikin confirms the effectiveness of its patented streamer technology, which successfully inactivated more than 99,9% of Novel Coronavirus (SARS-CoV-2) after irradiating the virus for 3 hours.
The study has been conducted by Daikin Industries Ltd in cooperation with Professor Shigeru Kyuwa from the Department of Biomedical Science of the University of Tokyo, and a group of research led by Professor Shigeru Morikawa from the Department of Microbiology of the Okayama University of Science.
The tests described herein only concern the patented Streamer Technology. The effects of products equipped with Streamer Technology or the effects in actual use environment may differ. For more information on the Daikin products incorporating the Streamer Technology, please refer to the relevant product information.
EXPERIMENTAL RESULTS
The research team conducted an experiment where the viruses were irradiated for a duration of 3 hours with Daikin Flash Streamer technology.
The results of this experiment showed that:
Flash Streamer discharge inactivated 93,65% of coronavirus (SARS-CoV-2) after an irradiation time of 1 hour
Flash Streamer discharge inactivated 99,97% of coronavirus (SARS-CoV-2) after an irradiation time of 3 hours

ABOUT STREAMER TECHNOLOGY

Streamer technology, developed by Daikin in 2004, performs an oxidative decomposition of harmful substances. The Streamer discharge is a type of plasma discharge featuring an innovative air purification technology that stably generates high-speed electrons.
Its oxidative decomposition capability is much higher than the conventional plasma discharge (glow discharge). Moreover, when combined with air components, these high-speed electrons have a capability for powerful oxidative decomposition that continuously remove odours, bacteria and indoor air pollutants such as formaldehyde.
Every year in May we will provide an update of this text.
