Since the structure of HI, AI and H1N1 virus are similar, Coway’s developed stronger ‘Anti-virus’ filter combinedwith more natural extracts based on pre-existing HI filter

Coway’s true HEPA filter has 99.9% efficiency on removing virus and bacteria, however, captured virus on filter can cause second contact to human beings

Additional separate custom filter for virus particularly for H1N1(Swine flu) influenza

Pre-existing HEPA filter can be replaced by anti-virus HEPA filter combined with natural extract for
