3.1.3
efficiency
ratio of the amount of aerosol filtered by the filter element to the amount of aerosol before filtration when the filter element is tested
3.1.4
penetration
ratio of the aerosol concentration filtered by of the filter element to the aerosol concentration before filtration when the filter element is tested
3.1.5
separator-style filter
filter with the filter medium is folded back according to the required depth and forth into the filter element, which is supported and separated by a corrugated partition between the folded filter medium to form an air channel
