These tests cover the 500 Series, which is designed for demanding professional and large-scale applications, as well as the CZ02 series, which addresses the needs of smaller and medium-sized indoor spaces.<\/p>\n<p>The tests document the ability of OH-Feel generators to produce hydroxyl radicals (OH), a natural oxidative mechanism that contributes to the reduction of microbial load, odors, and airborne pollutants. The results confirm the consistent performance of each model group, highlighting the differences and advantages depending on the scope of application and the specific requirements of the space.<\/p>\n<div id=\"title-1442046363\" class=\"container section-title-container\" style=\"overflow:hidden;\"><h3 class=\"section-title section-title-normal\"><b ><\/b><span class=\"section-title-main\">View Efficacy studies<\/span><b ><\/b><\/h3><\/div>\n<div class=\"accordion\">\n\t<div id=\"accordion-443444452\" class=\"accordion-item\">\n\t\t<a id=\"accordion-443444452-label\" class=\"accordion-title plain\" href=\"#accordion-item-oh-feel-500-series,-cz-series,-fc08a,-qtv1\" aria-expanded=\"false\" aria-controls=\"accordion-443444452-content\">\n\t\t\t<button class=\"toggle\" aria-label=\"Toggle\"><i class=\"icon-angle-down\" aria-hidden=\"true\"><\/i><\/button>\n\t\t\t<span>OH Feel 500 Series, CZ Series, FC08A, QTV1<\/span>\n\t\t<\/a>\n\t\t<div id=\"accordion-443444452-content\" class=\"accordion-inner\" aria-labelledby=\"accordion-443444452-label\">\n\t\t\t\n<style>\n#divider-1418435656 {\n  max-width: 100%;\n  background-color: rgb(56, 183, 172);\n}\n<\/style>\n\n<style>\n#divider-2094069674 {\n  max-width: 100%;\n  background-color: rgb(56, 183, 172);\n}\n<\/style>\n\n<div id=\"divider-1418435656\" class=\"is-divider divider clearfix \"><\/div>\n\t<div id=\"stack-2549779885\" class=\"stack stack-col justify-start items-stretch\">\n\t\t\n<div class=\"row row-divided\"  id=\"row-1809937783\">\n\n\t<div id=\"col-57307358\" class=\"col medium-4 small-12 large-4\"  >\n\t\t\t\t<div class=\"col-inner\"  >\n\t\t\t\n\t\t\t\n<div class=\"report-summary\">\n<h4>Hydroxyl UV Lamp Efficacy &#8211;

500A<\/p>\n<p><strong>Testing laboratory:<\/strong> Guangdong Detection Center of Microbiology (Gmicro)<\/p>\n<p><strong>Test standard:<\/strong> GB 21551.3-2010, Appendix A <strong>Report number:<\/strong> 2020FM06362R02D <strong>Issue date:<\/strong> 2020-05-07<\/p>\n<h3>1. Testing facility credibility<\/h3>\n<p>The Guangdong Detection Center of Microbiology (Gmicro) is a government-operated microbiological laboratory with international accreditation from CNAS and ILAC-MRA. It is one of China\u2019s leading testing institutions for air purification, antimicrobial performance, and environmental safety, and its certifications are widely accepted in Europe, Asia, and international product compliance evaluations.<\/p>\n<h3>2. Description of tests conducted<\/h3>\n<p>Testing was conducted in accordance with <strong>GB 21551.3-2010 (Appendix A)<\/strong>, which evaluates the airborne bactericidal performance of air-cleaning devices. The test organism used was <strong>Escherichia coli (strain 8099)<\/strong>.<\/p>\n<p>A sealed <strong>30 m\u00b3 test chamber<\/strong> was conditioned, and the <strong>OH-FEEL Hydroxyl Air Protection System<\/strong> was operated at maximum airflow (\u201c0H1\u201d and \u201c0H2\u201d modes) for a total duration of <strong>2 hours<\/strong>.<\/p>\n<p>Air samples were collected using a <strong>JWL-6 six-stage microbial air impact sampler<\/strong> at a flow rate of <strong>28.3 L\/min<\/strong>. Control samples were collected for 1 minute, while test samples were collected for 5 minutes.<\/p>\n<p>Natural microbial decay was mathematically removed to ensure that all observed reductions were attributable solely to the operation of the OH-FEEL device.<\/p>\n<h3>3. Summary of test findings<\/h3>\n<p><strong>Initial airborne E. coli concentration (0-hour control):<\/strong><\/p>\n<ul>\n<li>9.9 \u00d7 10<sup>4<\/sup> cfu\/m\u00b3<\/li>\n<li>9.3 \u00d7 10<sup>4<\/sup> cfu\/m\u00b3<\/li>\n<li>9.7 \u00d7 10<sup>4<\/sup> cfu\/m\u00b3<\/li>\n<\/ul>\n<p><strong>After 2 hours of OH-FEEL operation:<\/strong><\/p>\n<ul>\n<li>8.2 \u00d7 10<sup>2<\/sup> cfu\/m\u00b3 \u2192 97.95% reduction<\/li>\n<li>9.6 \u00d7 10<sup>2<\/sup> cfu\/m\u00b3 \u2192 97.33% reduction<\/li>\n<li>8.5 \u00d7 10<sup>2<\/sup> cfu\/m\u00b3 \u2192 98.09% reduction<\/li>\n<\/ul>\n<p><strong>Average sterilization rate:<\/strong> 97.79%<\/p>\n<h3>4.

Description of the Tests Performed<\/h3>\n<p>The OH-Feel OH500F08 underwent multiple medical grade evaluations, including:<\/p>\n<ul>\n<li>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<li>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<li>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 &lt;5 \u00b5W\/cm\u00b2. (Page 4)<\/li>\n<li>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<li>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<h3>3. Staphylococcus albus Disinfection Test (Medical-Grade Standard)<\/h3>\n<p>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<p><strong>Results:<\/strong><\/p>\n<ul>\n<li>1 hour: 99.79% kill rate (Staphylococcus albus)<\/li>\n<li>2 hours: 99.97% kill rate<\/li>\n<li>3 hours: 99.97% kill rate<\/li>\n<\/ul>\n<p>These disinfection levels meet \u2014 and in many cases exceed \u2014 requirements for hospital air sterilization devices.<\/p>\n<h3>4. Summary Statement<\/h3>\n<p>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<ul>\n<li>Ultra low ozone emission (~3 ppb)<\/li>\n<li>Zero UV leakage<\/li>\n<li>High circulating air volume (477.3 m\u00b3\/h)<\/li>\n<li>Strong UV sterilization output (175.2 \u00b5W\/cm\u00b2)<\/li>\n<li>&gt;99.97% microbial elimination performance<\/li>\n<\/ul>\n<p>This confirms the OH500F08 is suitable for use in medical environments requiring validated air sterilization.<\/p>\n<p><strong>Report No.:<\/strong> 2022FM10597R01E<\/p>\n<p><strong>Test Completion Date:<\/strong> 2022-06-24<\/p>\n<p>This summary is provided for clarity.<\/p>\n<p>Refer to the original test report for full data and methodology.<\/p>\n<\/div>\n\t<a id=\"btn-1506160611\" href=\"https:\/\/ohfeel.gr\/wp-content\/uploads\/2025\/12\/OH-Feel-500F08-\u2013-Safety-Efficacy-\u2013-Hospital-Environmental-Performance-Evaluation-Ozone-Airflow-UV-Leakage-Microbial-Reduction-Tests-GB-28235-2020-\u2013-Summary-\u2013-2022.pdf.pdf\" class=\"button primary expand\" >\n                        <span>Download Summary<\/span>            \t<\/a>\n    \n<style>\n#btn-1506160611 {\n  border-radius: 99px!important;\n}\n<\/style>\n\t\n\n\t<a id=\"btn-3963867936\" href=\"https:\/\/ohfeel.gr\/wp-content\/uploads\/2025\/12\/OH-Feel-500F08-\u2013-Safety-Efficacy-\u2013-Hospital-Environmental-Performance-Evaluation-Ozone-Airflow-UV-Leak-Microbial-Reduction-Tests-GB-28235-2020-\u2013-Guangdong-Microbiology-Institute-\u2013-2022.-pdf.pdf\" class=\"button primary expand\" >\n                        <span>Download Study<\/span>            \t<\/a>\n    \n<style>\n#btn-3963867936 {\n  border-radius: 99px!important;\n}\n<\/style>\n\t\n\n\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\n\t\n\n<\/div>\n\n\t\t<\/div>\n\n        \n<style>\n#section_1403732466 {\n  padding-top: 30px;\n  padding-bottom: 30px;\n}\n<\/style>\n\t<\/section>\n    \t\n\t<\/div>\n\t\n\t\n\t<div id=\"ohfeel500508a-hospital-efficay-safety-popup\"\n\t     class=\"lightbox-by-id lightbox-content mfp-hide lightbox-white open-lightbox\"\n\t     style=\"max-width:800px ;padding:20px\">\n\t\t\n\t<section class=\"section\" id=\"section_9191774\" >\n\t\t<div class=\"section-bg fill\"  >\n\t\t\t        \n\t\t\t            \n\t\t\t\t\t\t\n\n\t\t<\/div>\n\n\t\t\n\n\t\t<div class=\"section-content relative\">\n\t\t\t\n\n<div class=\"row\"  id=\"row-2057728221\">\n\n\n\t<div id=\"col-548141328\" class=\"col small-12 large-12\"  >\n\t\t\t\t<div class=\"col-inner text-center\"  >\n\t\t\t\n\t\t\t\n\n<div class=\"ux-logo has-hover align-middle ux_logo inline-block\" style=\"max-width: 100%!important;
