50 Cities Inc. Creates Ultraviolet Air Purification System

After five-plus years of research and development scientists at 50 Cities Inc. announced the successful development, installations and testing of a scalable solution to purify the air in areas where people gather.

Through the innovative use of Ultraviolet Germicidal Irradiation (UVGI) over 400-plus pathogens types can be disabled (unable to reproduce or infect by damaging their DNA). Eliminating bacteria, mold and viruses from the air. Software-enabled airflow modeling optimizes the pathogen exposure to UVC thereby exchanging the air in a 1,000 square foot room every 20 minutes continuously, 24/7/365.
