CZ02 Formaldehyde, Benzene & TVOC Removal Test Summary<\/h2>\n

OH-Feel CZ Series CZ02<\/strong><\/p>\n

Guangdong Detection Center of Microbiology (GDDCM)<\/strong><\/p>\n

Standard:<\/strong> QB\/T 2761-2006<\/p>\n

Test Chamber:<\/strong> 1.5 m\u00b3<\/p>\n

Report No.:<\/strong> 2020FM11788R02D<\/p>\n

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

The Guangdong Detection Center of Microbiology (GDDCM) is a nationally recognized testing laboratory in China specializing in chemical pollutant analysis, microbiological safety, and indoor air quality evaluation.<\/p>\n

It is widely used for independent third-party verification of air purification systems.<\/p>\n

2. Description of the Test<\/h3>\n
    \n
  • Standard Used:<\/strong> QB\/T 2761-2006 (Air purifier chemical removal test standard)<\/li>\n
  • Device Tested:<\/strong> OH-FEEL Hydroxyl Air Protection System (Model: CZ02, representative of CZ series variants)<\/li>\n
  • Test Chamber Volume:<\/strong> 1.5 m\u00b3<\/li>\n
  • Pollutants Tested:<\/strong> Formaldehyde, Benzene, Total Volatile Organic Compounds (TVOC)<\/li>\n
  • Exposure Duration:<\/strong> 12 hours<\/li>\n
  • Comparison Method:<\/strong> Pollutant concentration after 24 hours in a blank cabin compared with an OH-FEEL operating cabin<\/li>\n<\/ul>\n

    3. Key Results<\/h3>\n

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

      \n
    • Blank cabin concentration: 1.28 mg\/m\u00b3<\/li>\n
    • Test cabin concentration: 0.590 mg\/m\u00b3<\/li>\n
    • Reduction rate: 53.9%<\/strong><\/li>\n<\/ul>\n

        \n
      • Blank cabin concentration: 0.826 mg\/m\u00b3<\/li>\n
      • Test cabin concentration: 0.325 mg\/m\u00b3<\/li>\n
      • Reduction rate: 60.7%<\/strong><\/li>\n<\/ul>\n

        Total Volatile Organic Compounds (TVOC):<\/strong><\/p>\n

          \n
        • Blank cabin concentration: 4.82 mg\/m\u00b3<\/li>\n
        • Test cabin concentration: 2.03 mg\/m\u00b3<\/li>\n
        • Reduction rate: 57.9%<\/strong><\/li>\n<\/ul>\n

          4. Summary Statement<\/h3>\n

          Testing performed by the Guangdong Detection Center of Microbiology confirms that the OH-FEEL Hydroxyl Air Protection System<\/strong> significantly reduces indoor chemical pollutants, including formaldehyde, benzene, and total volatile organic compounds (TVOCs), in a sealed 1.5 m\u00b3 chamber over a 12-hour operating period.<\/p>\n

          These results demonstrate effective breakdown of harmful chemical gases using hydroxyl radical oxidation and support the OH-FEEL system\u2019s role in improving indoor air quality.<\/p>\n
