Amid rising concern about the effects of indoor air pollution, Emerald Air is seeking crowd-funding for a new smart air system for

offices and homes. The Emerald Air consists of two devices that can operate together or independently of each other: an Emerald air sensor that monitors pollutant, temperature and humidity levels, displaying the results on a smartphone app; and an Airadicate smart air purifier that filters out allergens, carcinogens and other pollutants and uses UV LED disinfection technology to kill viruses and bacteria.
