2. Spread of serious illnesses Need for air purification is expanding worldwide New H1N1 influenza pandemic Concern over a pandemic of a human form of the avian flu Substantial increase in people allergic to mold and dust mites in homes Worsening of epidemics in schools, hospitals, and old age homes

3. By electrolyzing tap water containing chloride ions, 2 types of active oxygen are generated, namely hypochlorous acid and the OH radical What is electrolyzed water? SANYO’s electrolyzed water technology and its benefits Tap water Electrolyzed water Chloride ions (CI-) Hypochlorous acid (HCIO) + OH radicals

4. 1987 2000 2001 History of SANYO’s electrolyzed water technology Electrolyzed water bacteria-eliminating system for cup-type beverage vending machines Pool water purification system (Aqua Clean) Electrolyzing phosphorous-eliminating device Electrolytic nitrogen removal system Washing machine with detergent-less setting Expanding development for products that purify water and air using electrolyzed water technology Creation of products equipped with virus washer 2008 Air purifier for household use (disinfectant electrolyzed mist) Humidifier (disinfectant filter) Humidifying ceramic fan heater (disinfectant filter) Duct-type air purification system for movie theaters (disinfectant element) Portable air purifier (disinfectant electrolyzed mist) 2006 Air purification system for commercial use (disinfectant element) 2007

5. virus washer’ technology concept Protect your loved ones from viruses.

6. Air purification system for commercial use Two types of ‘virus washer’ technology Air purifier for household use Application of electrolyzed water for air purification (1) Disinfectant element technology Disinfectant element Electrode Pump Disinfectant electrolyzed mist technology Airborne viruses are inactivated all year long, through the use of a long-lasting mist of electrolyzed water that reaches every corner of the room (2) Electrolyzed mist generation (3) Electrolyzed mist spouted Ultrasonic vibrator Electrode (1)Electrolyzed water is created Airborne viruses are inactivated by circulating air through an element containing electrolyzed water Electrolyzed water trickling down where the electrolyzed water is generated

7. Effect of contact with a disinfectant element soaked with electrolyzed water [ Joint research with the Gunma Prefectural Institute of Public Health and Environmental Sciences] Inactivates virus infectivity by 99% or more! Disinfectant element technology Verification of effectiveness against the Influenza virus (H1N1) Effect of contact with a disinfectant electrolyzed mist made from electrolyzed water [ Joint research with the Gunma Prefectural Institute of Public Health and Environmental Sciences] Swab Inactivates more than 99% Inactivates more than 99% Before passing through the disinfectant element After passing through the disinfectant element Viral infectivity residual ratio (%) 100 % 0 % Before mist treatment After mist treatment Vital infectivity residual ratio (%) 100 % 0 % Disinfectant electrolyzed mist technology 99 % 減少 99 % 減少

8. Norovirus (FCV used as a surrogate for testing) Avian flu virus (H5N3) Influenza virus (H1N1) Outline of virus inactivation verification (1) Envelope type virus (lipid membrane structure) Non-envelope type virus (no lipid membrane structure) Structural types of viruses Direct contact with electrolyzed water Disinfectant electrolyzed mist Disinfectant element

9. Representative infectious diseases Disinfecting property Structure Structural types for infectious airborne (droplet / aerosol) viruses Verification of infectivity inactivation for both types of viruses! Lipid membrane structure (envelope) New H1N1 influenza Avian flu Influenza Measles virus Spikes Structural protein (capsid) Genomes Envelope (outer wall of the lipid membrane) Alcohol: Effective No lipid membrane structure (non-envelope) Norovirus (infectious gastroenteritis) Alcohol: Low effectiveness Spikes Structural protein (capsid) Genomes Adenovirus (pharyngoconjunctival fever) Hypochlorous acid: Effective Outline of virus inactivation verification (2)

10. Destruction and elimination of the virus protein (Spike) were confirmed. Transmission electron microscope photograph of the influenza virus. < collaboration with Gunma Prefectural Institute of Public Health and Environmental Sciences > Possible scheme of the virus inactivation (1) 【 Before the contact with the electrolyzed water 】 【 After the contact with the electrolyzed water 】

11. Mechanism for inactivation of viruses using electrolyzed water Possible scheme of the virus inactivation (2) Virus spikes Damaged spike Infection by sticking to the cell Receptor Human cell (inside) Cannot stick to the cell (No infection) Viral infection Infection occurs when the “spikes” on the surface of a virus adhere to receptors on a human cell. Before exposure to electrolyzed water Neutralizing viruses with electrolyzed water The electrolyzed water destroys the virus spikes. The virus is no longer able to adhere to a cell, and it is neutralized. After exposure to electrolyzed water Electrolyzed water Receptor Human cell (inside) HClO ･ OH HClO HClO HClO HClO ･ OH ･ OH

12. Inactivates airborne viruses and allergens such as pollens using the power of water to “wash air” soaks in and oxidizes sticks on the surface and denatures acts on viruses & bacteria OH radicals viruses / floating bacteria allergens (pollen etc.) Hypochlorous acid odors (pet, cigarette, and other odors) Other outstanding functions of electrolyzed water inactivates more than 99% inactive disinfection inactivates reduction inactivates more than 99% 以上抑制 99 % 以上抑制 99 %

20. - It is good to have clean air, since you can easily catch a cold in crowded places. (Woman in her 20’s) - My child has a house dust allergies and gets symptoms in dusty places, so I am glad to able to come and watch a movie without worrying. (Woman in her 40’s) - I came down with the flu last January after watching a movie, and it was awful. I hope you will continue this effort since there has been a lot of concern about swine flu recently. (Woman in her 50’s) - Although I have been worried about catching the flu, I was able to relax and enjoy the movie.
