Ultra Violet Devices Inc. (UVDI) is one of the oldest and most respected ultraviolet disinfection companies in the world. It all began with the hard work and ingenuity of a single man. Three generations ago Luis Veloz was an engineer for Westinghouse when their R&D engineers developed and patented the first commercial ultraviolet lamps. Luis was excited by this new technology and in 1949 he purchased a Westinghouse UV lamp dealership. Early applications were difficult to develop, but Luis had a vision of how ultraviolet light might be widespread and effective. He formed Aquafine Corporation to focus on water disinfection. In 2003, UVDI launched its ALTRU-V line of air disinfection products. We have talked a good bit with past guests about the potential benefits and drawbacks for specific airstream UV disinfection with IAQ experts for three years it is time we hear from a respected manufacturer for their perspective. Let's see what they have to say and contribute we can contribute the discussion our own unique way on IAQ Radio.
