A new air filtration system is being installed at Union Hospital to eliminate airborne pathogens such as COVID-19.

The Energy Harness Active-Airflow fixture demonstrated Monday at the hospital draws in air and filters it using ultraviolet light before returning clean air to the room. The fixture is installed into standard ceiling grids found in most office buildings, schools and medical facilities.

One filter can clean a 16-feet by 16-feet room in 17 minutes, Energy Harness managing director Patricio Daneri said during the demonstration.
