Abstract One of the most frequently used methods to purify air contaminated by particles, in many industrial processes, is filter media. Although the performance of filter media is relatively well documented under standard conditions (humidity and ambient temperature), few studies are interested in the interaction between moisture and the deposition of particles collected. The proposed study aims to establish the performance of a fibrous media with aerosols composed of nanostructured solid… Expand

Effect of Humidity and Particle Hygroscopicity on the Mass Loading Capacity of High Efficiency Particulate Air (HEPA) Filters
The effect of humidity, particle hygroscopicity, and size on the mass loading capacity of glass fiber high efficiency particulate air filters was studied. Above the deliquescent point, the pressure… Expand
Modelling the pressure drop across HEPA filters during cake filtration in the presence of humidity
The modelling of the variation in the pressure drop across a HEPA filter during cake filtration in the presence of humidity was studied. A semi-empirical model was developed that considers the… Expand
Effect of relative humidity on loading characteristics of cellulose filter media by submicrometer potassium chloride, ammonium sulfate, and ammonium nitrate particles
Abstract This study aims to research the relative humidity (RH) effect of the cellulose filter media loading. The filter loading characteristics of test particles under various RHs (15%, 30%, 45%,… Expand
