An air monitor made by researchers at Washington University in St. Louis can detect COVID-19 in a room with an infected person within 5 minutes.
July 10, 2023 –
The team overcame that challenge using a technology called wet cyclone that samples the equivalent of 176 cubic feet of air in 5 minutes. A light on the device turns from green to red when the virus is detected, which the researchers said indicates that increased air circulation is needed. Current methods used for detecting viruses in the air take between 1 and 24 hours to collect and analyze samples. The existing methods usually require skilled labor, resulting in a process that doesn’t allow for real-time information that could translate into reducing risk or the spread of the virus, the researchers wrote.
