OH-Feel 500A – Airborne H1N1 Flu Virus Reduction Test<\/h2>\n

SUMMARY<\/strong><\/p>\n

OH-FEEL 500A<\/strong><\/p>\n

Guangdong Detection Center of Microbiology \u2013 GB 21551.3-2010 Appendix A<\/p>\n

1. Testing Facility Credibility<\/h3>\n

The Guangdong Detection Center of Microbiology (Gmicro) is a government-operated laboratory with international accreditation from CNAS and ILAC-MRA. It is widely recognized as one of China\u2019s most authoritative microbiological testing institutions, specializing in virology, environmental microbiology, and air purification performance testing. Its reports are accepted internationally for regulatory submission and scientific verification.<\/p>\n

2. Description of Tests Conducted<\/h3>\n

Testing was conducted in accordance with GB 21551.3-2010 (Appendix A)<\/strong>, using Influenza A (H1N1), strain A\/PR\/8\/34<\/strong>, propagated in MDCK cells.<\/p>\n

A sealed 30 m\u00b3 test chamber<\/strong> was used. The OH-Feel Hydroxyl Air Protection System<\/strong> was operated at maximum wind speed (level 5), with 0H1 and 0H2 modes<\/strong> activated for a continuous 2-hour treatment period<\/strong>.<\/p>\n

Airborne virus particles were quantified using the TCID method<\/strong>. Three control samples were collected at 0 hours, and three test samples were collected after 2 hours of operation. Natural viral decay was mathematically removed to ensure that all observed reductions were attributed solely to the OH-Feel system.<\/p>\n

3. Key Results<\/h3>\n

Initial airborne H1N1 concentration (0-hour control):<\/strong><\/p>\n

    \n
  • 1.73 \u00d7 105<\/sup> TCID\/m\u00b3<\/li>\n
  • 1.44 \u00d7 105<\/sup> TCID\/m\u00b3<\/li>\n
  • 2.44 \u00d7 105<\/sup> TCID\/m\u00b3<\/li>\n<\/ul>\n

    After 2 hours of OH-Feel operation:<\/strong><\/p>\n

      \n
    • 2.44 \u00d7 103<\/sup> TCID\/m\u00b3 \u2192 99.17% reduction<\/li>\n
    • 1.94 \u00d7 103<\/sup> TCID\/m\u00b3 \u2192 99.37% reduction<\/li>\n
    • 4.06 \u00d7 103<\/sup> TCID\/m\u00b3 \u2192 99.21% reduction<\/li>\n<\/ul>\n

      Average H1N1 removal rate:<\/strong> 99.25%<\/p>\n

      4. Summary Statement<\/h3>\n

      The results demonstrate that the OH-Feel Hydroxyl Air Protection System effectively eliminates airborne H1N1 influenza virus under controlled environmental conditions, achieving near-total viral removal within a two-hour treatment period.<\/p>\n
