Characteristics of Submicron-sized Aerosol Filtration and Pressure Drop of an Electret Filter Installed in an Air Diffuser in a Residential Apartment Unit
Electret filter Filtration Pressure drop
2016/3/28
We investigated submicron-sized aerosol filtration and the pressure drop of an electret filter called a “Flimmer filter.”
The fibers of the filter are aligned parallel to the direction of the airflow...
