Daikin's streamer technology inactivates more than 99.9% of the novel coronavirus (SARS-CoV-2)

Streamer technology & Coronavirus

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.

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.
