Webster and Ron talk with Dan about UV light. What’s so good about UV light? Well, it kills pathogens. But using UV light in the indoor environment requires engineering for safety and effectiveness. Dan explains the use of UV light along with the use of controls and sensors for room occupancy, toxin and virus levels, fans, and filters. And don’t forget that old technology - opening your window.
