PurisAir is an air-cleaning unit supported by an Air Quality Monitor. It can be wall-mounted or free-standing. It uses electro-foil filtration technology to remove contagious viruses, bacteria, and dust particles from an indoor space. The Air Quality Monitor measures the level of air eCo2 in an enclosed area. The monitor evaluates risk and offers guidance to individuals. The sensors are connected to provide data to a cloud-based platform which can be viewed by in real-time via Bluetooth. P4 PurisAir air cleaning technology acts as the third level of prevention for enclosed areas where an asymptomatic individual may be present. It reduces the risk of close proximity transference of infectious particles, and the need for maximum social distancing.
