Japanese Test Results

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

The tests described herein only concern the patented Streamer Technology. The effects of products equipped with Streamer Technology or the effects in actual use in an environment may differ. 

Measurement method 1:

Antibacterial test/bacterial removal test;
Testing organization: Japan Food Research Laboratories; Test  result certificate number 203120769-001;
Result of experiment: 99.99% removal/mould removal test; Testing organization: Japan  Food Research Laboratories; Test result certificate 204041635-001;
Result of experiment: 99.9% removal/Virus removal test; Testing  organization: Kitasato Research Center for Environmental Science; Test result certificate 21_0026 (issued by same organization); 
Result of experiment: 99.9% removal. These results will differ from actual location where product will be used. 2

Conditions of  experiment: Allergens were irradiated by streamer discharge and the breakdown of protein in the allergens was verified using the  ELISA method, cataphoresis, or an electron microscope. (Joint research with Wakayama Medical University.)

Measurement method 3: 
Virus removal test; Testing organization: Kitasato Research Center for Environmental Science; Test result certificate 21_0026 (issued  by same organization);
Result of experiment: 99.9% removal.

Test method 4: constant generation method; Test room: 22 to 24 m³;  Temperature: 23 ± 3°C; Humidity: 50 ± 20%; Ventilation condition: When concentration of 0.2 ppm is continually emanated, a removal  capacity of 0.08 ppm is maintained at 36 m³/h, which is within the guideline of the Ministry of Health, Labour and Welfare (Japan).  (This equates to the ventilation capacity of an approximately 65 m³ room.)
