Pressure Loss of Air Filters for General Ventilation at High Relative

In anticipation of the new European standard EN 779.2012 for air filters, which classifies air filters based on their lowest filtration efficiency, this article discusses the effect that high humidity has on pressure loss during exposure to different dusts. For example, individual test data show that variations of relative humidity cause significant changes in pressure loss if NaCl is present in the loading aerosol.
