HOSPITAL ACCREDITATION ANALYSIS SUMMARY<\/h2>\n

Guangdong Detection Center of Microbiology (CNAS Accredited Laboratory)<\/strong><\/p>\n

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

The Guangdong Detection Center of Microbiology (GDDCM) is a CNAS-accredited national laboratory specializing in medical disinfection standards, microbiological testing, sterilization performance, and air-quality safety evaluations. It is one of China\u2019s leading recognized authorities for medical grade air disinfection validation and HVAC compliance. This accreditation ensures strict adherence to ISO\/IEC 17025 laboratory competence requirements.<\/p>\n

2. Description of the Tests Performed<\/h3>\n

The OH-Feel OH500F08 underwent multiple medical grade evaluations, including:<\/p>\n

    \n
  • Ozone concentration assessment \u2014 measured according to GB 28235-2020. Results across repeated sampling averaged 0.006 mg\/m\u00b3 (~3 ppb), confirming extremely low ozone output. (Page 3)<\/li>\n
  • Circulating air volume measurement \u2014 conducted using the GB\/T 14295-2008 Appendix B method. The OH500F08 achieved an average circulating air volume of 477.3 m\u00b3\/h. (Page 4)<\/li>\n
  • UV leakage safety test \u2014 measured at a 30 cm perimeter distance as required by GB 28235-2020. UV radiation leakage was recorded as 0 \u00b5W\/cm\u00b2, meeting the strict requirement of <5 \u00b5W\/cm\u00b2. (Page 4)<\/li>\n
  • Ultraviolet radiation intensity (operational) \u2014 measured for 10 minutes at 1 minute intervals. The sterilization UV lamp maintained a stable average intensity of 175.2 \u00b5W\/cm\u00b2. (Page 5)<\/li>\n
  • Airborne bacteria removal test \u2013 40 m\u00b3 test chamber \u2014 GB test method. Reduction of natural airborne microbes reached: 92.83% after 2 hours; 92.94% after 3 hours. (Page 6)<\/li>\n<\/ul>\n

    3. Staphylococcus albus Disinfection Test (Medical-Grade Standard)<\/h3>\n

    The OH500F08 was tested in a controlled 20 m\u00b3 aerosolized bacterial chamber following the Technical Standard for Disinfection (Ministry of Health P.R. China). This test evaluates professional hospital grade sterilization capability. (Page 7)<\/p>\n

    Results:<\/strong><\/p>\n

      \n
    • 1 hour: 99.79% kill rate (Staphylococcus albus)<\/li>\n
    • 2 hours: 99.97% kill rate<\/li>\n
    • 3 hours: 99.97% kill rate<\/li>\n<\/ul>\n

      These disinfection levels meet \u2014 and in many cases exceed \u2014 requirements for hospital air sterilization devices.<\/p>\n

      4. Summary Statement<\/h3>\n

      Based on the official medical grade evaluations performed by the CNAS accredited Guangdong Detection Center of Microbiology, the OH-Feel OH500F08 meets the standards for hospital level air disinfection systems. It demonstrates:<\/p>\n

        \n
      • Ultra low ozone emission (~3 ppb)<\/li>\n
      • Zero UV leakage<\/li>\n
      • High circulating air volume (477.3 m\u00b3\/h)<\/li>\n
      • Strong UV sterilization output (175.2 \u00b5W\/cm\u00b2)<\/li>\n
      • >99.97% microbial elimination performance<\/li>\n<\/ul>\n

        This confirms the OH500F08 is suitable for use in medical environments requiring validated air sterilization.<\/p>\n
