Every year there seems to be another threat to our health that the media exploits. As most people are aware, the air in our homes sometimes is more contaminated than the outdoors. LeBlanc Heating has been investigating this issue for years. After researching many products, we have chosen Sanuvox air purifiers for several reasons. Using proprietary UV technology, the Sanuvox In-Duct Ultraviolet Air Sterilization System is designed to maximize exposure time between the air and the UV germicidal energy. The UV system has been proven to deliver the optimal UV germicidal dosage, penetrating the cell membrane, destroying the DNA structure of the virus.
