With UV exposure being a safety issue, EcoQuest takes this seriously.  We have a UV light intensity meter in-house which is calibrated to national standards.  The safety agencies (CSA & ETL) accept our data.  The levels in the attached spreadsheet are 3-4 times below the maximum exposure levels set by the federal government, meaning that a person would have to stare at the reflected light coming from the Fresh Air UV Bulb for nearly 24 hours at less than 1” from the grill before their retina would have been over exposed to UV.
