OH-Feel 500A – TVOC & Formaldehyde Purification Test Summary<\/h2>\n

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

Guangdong Detection Center of Microbiology \u2013 JG\/T 294-2010<\/strong><\/p>\n

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

The Guangdong Detection Center of Microbiology (Gmicro) is a CNAS- and ILAC-MRA\u2013accredited, government-operated laboratory recognized internationally for environmental, chemical, and microbial testing. Gmicro\u2019s results are accepted for regulatory submissions, air quality evaluation, and product performance verification worldwide.<\/p>\n

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

Testing followed JG\/T 294-2010, evaluating TVOC and formaldehyde purification efficiency in a controlled 30 m\u00b3 chamber.<\/p>\n

Pollutants Tested:<\/strong><\/p>\n

    \n
  • Formaldehyde (HCHO)<\/li>\n
  • Total Volatile Organic Compounds (TVOC)<\/li>\n<\/ul>\n

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

      \n
    • Initial pollutant concentration measured at 0h.<\/li>\n
    • Chamber sealed and the OH-Feel hydroxyl generator operated for 1 hour.<\/li>\n
    • Natural decay was recorded in a blank chamber to calculate net purification efficiency.<\/li>\n<\/ul>\n

      3. Key Results<\/h3>\n

      Formaldehyde (HCHO) Reduction:<\/strong><\/p>\n

        \n
      • Control chamber natural decay: 0.9%<\/li>\n
      • Initial concentration: 1.16 mg\/m\u00b3<\/li>\n
      • After 1 hour with OH-Feel: 0.18 mg\/m\u00b3<\/li>\n
      • Total decay: 84.3%<\/li>\n
      • Net purification efficiency: 83.4%<\/li>\n<\/ul>\n

        TVOC Reduction:<\/strong><\/p>\n

          \n
        • Control chamber natural decay: 1.0%<\/li>\n
        • Initial concentration: 4.80 mg\/m\u00b3<\/li>\n
        • After 1 hour with OH-Feel: 1.02 mg\/m\u00b3<\/li>\n
        • Total decay: 78.8%<\/li>\n
        • Net purification efficiency: 77.8%<\/li>\n<\/ul>\n

          Overall Result:<\/strong> The OH-Feel Hydroxyl Air Protection System achieved strong chemical purification performance, removing formaldehyde by 83.4% and TVOC by 77.8% within one hour in a 30 m\u00b3 chamber.<\/p>\n
