‘Disinfectant Electrolyzed Mist’ Internal assessment by SANYO Electric Co., Ltd.
 
  1. Tests have been performed on the efficacy of a) Electrolyzed Water, b) the Electrolyzed Disinfectant Element (as used in the Commercial Use Virus Washer and c) the Electrolyzed Disinfectant Mist (as used in the Home Use Virus Washer).
  2. Suppression (reduction) rates are from the treated sample.
  3. Testing method: Mould particles were suspended in an approximately 9-cubic metre test chamber and disinfectant electrolytic mist was released into the chamber. An air sampler was used to evaluate the number of residual airborne mould particles. Testing organisation: Japan Food Research Laboratories.
  4. Testing method: Disinfectant electrolytic mist was released into a 0.275-cubic metre test chamber containing pollen particles, and the reduction in the number of pollen particles was evaluated by the enzyme antibody method. Testing organisation: Osaka Medical College.
  5. Testing method: Disinfectant electrolytic mist was released into a 0.275-cubic metre test chamber containing dust mite particles, and the reduction in the number of dust mite particles was evaluated by the enzyme antibody method. Testing organisation: Kobe University School of Medicine.
  6. Testing method: Disinfectant electrolytic mist was released into a 0.275-cubic metre test chamber containing dog and cat dander allergens, and the reduction in the number of dander allergens was evaluated by the enzyme antibody method (ELISA). Testing organisation: Oriental Yeast Co., Ltd.
  7. Test method: Three chemicals with different odours (acetaldehyde, acetic acid and ammonia) were released into a 0.275-cubic metre test chamber and passed through a disinfectant element. The percentage of residual gas was then measured. Testing organisation: SANYO Electric Co., Ltd.
  8. Test method: Four chemicals with different odours (ammonia, acetic acid, trimethylamine and methyl mercaptan) were released into a 0.275-cubic metre test chamber and passed through a disinfectant element. The percentage of residual gas was then measured. Testing organisation: SANYO Electric Co., Ltd.
  9. More than 99.9% of airborne bacteria removed after 5 minutes. Test method: Bacteria were suspended in a 2-cubic metre test chamber and the air purification system (Virus Washer with Disinfectant Element) was operated. Microbes remaining in suspension were trapped periodically and the change over time was evaluated by the pour plate method. Testing organisation: Gunma Prefectural Institute of Public Health and Environmental Sciences with SANYO Electric Co., Ltd.
  10. More than 99% of airborne viruses were removed after one passage through the disinfectant element. Test method: Air containing suspended viruses was passed through the Disinfectant Element containing electrolyzed water, after which the remaining airborne viruses were trapped and residual virus populations were evaluated in cell cultures by TCID50 assay. Testing organisation: Gunma Prefectural Institute of Public Health and Environmental Sciences.
  11. Airborne Viruses 98% reduction. A Virus Washer with Disinfectant Element was operated in a 8-metre square laboratory, where virus was sprayed into the air for 30 minutes. Fifty minutes after the spraying was stopped, the viruses were collected and their infectious strength was measured with cultured cells. Testing organisation: The Kitasato Institute Medical Centre Hospital, Research Centre for Medical Environment.
  12. Test method: Disinfectant Electrolytic Mist was released into a 1-cubic metre test chamber containing airborne viruses. The viruses were collected and their infectious strength was measured by TCID50 Assay. Testing organisation: The Kitasato Institute Medical Centre Hospital, Research Centre for Medical Environment.
  13. Test method: Disinfectant Electrolytic Mist was released into a 1-cubic metre test chamber containing airborne bacteria. An air sampler was used to evaluate the number of residual airborne bacteria. Testing organisation: The Kitasato Institute Medical Centre Hospital, Research Centre for Medical Environment.
