DAIKIN ’ S PATENTED STREAMER TECHNOLOGY INACTIVATES
MORE THAN 99.9 % OF THE CORONAVIRUS
bold statement indeed , but one backed by science .
A Daikin can now confidently confirm the effectiveness of their patented streamer technology , which successfully inactivates more than 99.9 % of the novel coronavirus after irradiating the virus .
Daikin ’ s 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 removes odours , bacteria and indoor air pollutants such as formaldehyde .
“ Ventilation and air purification technologies have proven to play an important role in limiting the spread of Covid-19 . Public confined spaces have shown to be the biggest risk for the spread of the virus . Improving indoor air quality has always been part of Daikin ' s focus . We do not only want to provide a comfortable indoor temperature , we also aim to provide healthy air . This has been a focus for many years . An example of this is the streamer technology .
“ Over the years we have been continuously working on proving the effectiveness of this technology against various viruses and bacteria . We are proud to announce that our Daikin streamer technology inactivates more than 99.9 % of the coronavirus ( SARS-CoV-2 ) after irradiating the virus for only 3 hours with streamer discharge . We expect that this technology will support us in future in providing solutions that will play an important role in reducing the spread of this , and similar viruses in general ,” says Koen Van Wynendaele , managing director of Daikin South Africa .
The study has been conducted by Daikin Industries Ltd in co-operation with professor Shigeru Kyuwa from the Department of Biomedical Science of the University of Tokyo , and a group of researchers led by professor Shigeru Morikawa from the department of Microbiology at the Okayama University of Science .

The research team conducted an experiment where the viruses were irradiated for a duration of three hours with Daikin Flash Streamer technology . The results of this experiment showed that :
• Flash streamer discharge inactivated 93,65 % of coronavirus ( SAR-CoV-2 ) after an irradiation time of 1 hour .
• Flash streamer discharge inactivated 99,97 % of coronavirus ( SAR-CoV-2 ) after an irradiation time of 3 hours
