"By strategically placing a PAC (portable air cleaner) in the ward, the trajectory of aerosols emitted during a patient's cough can be altered, causing them to move toward the side of the PAC.
Aerosols that are not effectively purified by the PAC can then be directed toward the outlet for removal..
the targeted aerosol removal capacity of the ventilation system can be enhanced by 38.5%–62.5 % through the placement of a PAC..
The implementation of PACs led to a remarkable 86.9 % decrease in the average viral load on the body surface of HCWs (healthcare workers)..
Combining PACs with a system that provides a ventilation rate of 15 ACH could effectively reduce the passive [virus] exposure risk to below 35.0 %..
After the installation of PACs, there was a substantial 58.9 % decrease in the average aerosol deposition rate on the walls..
PACs installed inwards led to an increase in energy efficiency of between 12.6 % and 31.1 % on typical winter and summer days.."
