The PHI Package Unit by RGF® is designed to eliminate sick building syndrome risks by reducing odors, air pollutants, VOCs (chemical odors),
smoke, mold bacteria and viruses*. Why Use RGF’s Photohydroionization Technology? Germicidal UV light rays have been used for decades by the medical industry as a method for destroying micro-organisms (germs, viruses,
bacteria). UV light is dependable and can be easily installed in HVAC systems. Germicidal UV light is effective in reducing only the
airborne micro-organisms that pass directly through the light rays. However, germicidal UV light has little to no effect on gases, vapors
or odors. Photohydroionization Advanced Oxidation, which is an active system, on the other hand, is very effective on gases, vapors, VOCs, and odors within the occupied space. Important for the Alehouse employees and guests is that actual lab tests show over 99% reductions of airborne bacteria, mold, odors and viruses. The purchase and installation of this system was made possible with a grant from the Michigan Occupational Safety and Health Administration (MIOSHA) and the Alehouse thanks that group for their support in helping us install this and other equipment to keep our employees and guest as safe as possible.
