UVCBOX Light is lamp that is specially designed to be installed inside your existing HVAC system. It kills dangerous viruses and pathogens that are too small for regular filters to trap. HVAC Filters are not capable of removing small particles from the air such as coronavirus, influenza (flu) or rhinovirus (cold). UVCBOX is the first plug and play UVC system for HVAC. Your system does not need to be upgraded or changed. UVCBOX can be installed by a certified technician safely and easily in under an hour.
