OH-Feel 500F08 – OZONE EMISSIONS ANALYSIS SUMMARY<\/h2>\n

NCSR \u201cDemokritos\u201d<\/strong> \u2014 Atmospheric Chemistry & Innovative Technologies Laboratory<\/p>\n

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

The Atmospheric Chemistry & Innovative Technologies Laboratory of NCSR \u201cDemokritos\u201d is one of Greece\u2019s leading government scientific institutions, internationally recognized for precision ozone measurement, air quality analysis, and atmospheric chemistry.<\/p>\n

All measurements were performed using a calibrated Thermo Scientific i49 automatic ozone analyzer in accordance with EN 14625:2012<\/strong>.<\/p>\n

2. Description of the Test<\/h3>\n
    \n
  • Standard:<\/strong> EN 14625:2012<\/li>\n
  • Device Tested:<\/strong> OH-Feel OH500F08 (KJ488FK08A)<\/li>\n
  • Rated Coverage:<\/strong> Up to 60 m\u00b2<\/li>\n
  • Test Environment:<\/strong> 18 m\u00b2 sealed room<\/li>\n
  • Test Duration:<\/strong> 22 hours continuous operation<\/li>\n
  • Pre-test Baseline:<\/strong> 2 hours<\/li>\n<\/ul>\n

    The test intentionally used an extremely small, sealed 18 m\u00b2 room while the OH500F08 is designed for spaces up to 60 m\u00b2. This created a high-concentration stress test far beyond normal operating conditions, exaggerating ozone levels for safety evaluation. Even under these conditions, ozone remained well within global health limits.<\/p>\n

    3. Key Results<\/h3>\n

    Initial ozone level (pre-operation):<\/strong> 9.7 ppb<\/p>\n

    Ozone level during maximum operation:<\/strong> stabilized at 30.5 ppb after 22 hours<\/p>\n

    Ozone level after device shutdown:<\/strong> 17.7 ppb<\/p>\n

    4. Safety Interpretation<\/h3>\n

    The globally recognized medical-grade indoor ozone safety limit is 50 ppb (0.050 ppm)<\/strong>. This limit is used by U.S. FDA medical device regulations, EU indoor air recommendations, and WHO guidance.<\/p>\n

    The measured OH-Feel result of 30.5 ppb<\/strong> remains safely below the 50 ppb threshold even under extreme test conditions.<\/p>\n

    Because the test was performed in an 18 m\u00b2 sealed room \u2014 significantly smaller than the 60 m\u00b2 rated coverage \u2014 real-world ozone levels during normal use will be substantially lower than the measured value.<\/p>\n
