Specifications include, but are not limited to: Ultraviolet light (UV-c) systems that are capable of cleansing indoor air through both filtration and inactivation of pathogens and systems that that can in stationery locations as well as units that are mobile using their own systems to navigate indoor environments are desired. Other innovative indoor air cleansing and pathogen deactivation systems will be considered. Stationary units should be capable of purifying indoor air and decontaminate surfaces with a minimum capacity to control a space of 1000 square feet and be scalable from that minimum. Stationary units should be either concealed units or made of materials and designed to be easily placed in classrooms, offices, cafeterias, patient care areas and other indoor locations where air cleaning units are traditionally placed. The units should blend easily with standard institutional décor. Autonomous Units must be able to decontaminate surfaces in a minimum space of 10000 square feet.
