Influence and Analysis of Aerosol Concentration on Filtration Efficiency of Air Filter Media
The particle counter is one of the commonly used methods to test the filtration efficiency of air filter media.In order to verify the relationship between aerosol concentration and the minimum efficiency and the most penetrate particle size(MPPS)of air filter medias,the aerosol concentration was varied by changing the flow rate of aerosol and sheath gas,and different types of filter medias were tested.The conclusion was drawn that when the aerosol concentration changes,the filtration efficiency of filter media will also change.
