UV Whole Home Induct Air Purification – EnviroAire IAQ Testing Results. Test results from Airmid Healthgroup (a certified allergy testing lab) have proven the effectiveness of the EnviroAire UV Whole Home In-Duct Air Purification System.The tests verified that the device was capable of both sterilizing microorganisms and reducing volatile organic compounds (VOCs), and confirmed that the EnviroAire's UV light was "highly effective" at ...
Electrical substation - Wikipedia substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels.
