Abstract Filter media have been well used in a variety of industrial applications, where the dust concentration and system velocity are always different and varying. Thus, it is important to understand the effect of different application environments on filter performance in order to help guiding the filter media and test methods design. A series of experiments have been carried out to study the effect of different dust loading rates on filter pressure drop. The objective was to figure out if there is any influence of dust loading rate on affecting the pressure drop over filter media with loaded mass. High efficiency filter media have been utilized in this study. Two different filter media loaded with medium size dust under two different face velocities (10 cm/s and 20 cm/s) and four different dust loading rates were studied here. For each combination of dust loading rate, face velocity and filter media, one curve indicating pressure drop vs. dust mass loaded was obtained. The study verifies the dust feeding rates do have effects on filter pressure drops evolution with loaded dust mass. Membrane filter media has a much stable pressure drop under different dust feeding rates, but glass fiber filter has an obviously distinct pressure drop under different dust feeding rates. Besides, dust loading rate brings a much significant difference on pressure drop for glass fiber filter under low face velocity than higher face velocity.
