    What is Porosity? - Universal Air Filter

    The term porosity, measured in PPI (Pores Per Inch) designates the number of pores in one linear inch. Counting the pores is a visual indication of porosity which directly coincides with an airflow tested measurement that defines a range of …

    Does Depth Affect A filter's porosity?
    Filters whose porosity decreases with depth are often more efficient at removing solute from a fluid than filters with a uniform porosity. We investigate this phenomenon via an extension of homogenization theory that accounts for a macroscale variation in microstructure.

    Are pore-size graded multilayered membrane filters effective in reducing foulant retention?
    Binan Gu 1,*, Lou Kondic 2,†, and Linda J. Cummings 2,‡ Pore-size graded multilayered membrane filters have shown improved performance in terms of foulant retention and filtrate production. In this work, we model such a filter as a network of circularly cylindrical pores, whose radii decrease linearly across several layers of membrane material.

    Do higher porosity filters increase tortuosity?
    Before closing, we note in passing some perhaps unexpected features of the results. First, comparing Fig. 12, Fig. 12, we observe that filters with higher porosity show a smaller increase in tortuosity with β.

    Does a constant porosity gradient separate a reservoir?
    As discussed in the Introduction, a quantitative understanding of this behaviour is an open question. Specifically, we consider an industrial process whereby a filter with a unidirectional constant porosity gradient separates two reservoirs, and a flow is induced through the filter in the same direction as the gradient in porosity.

    What is the performance of a filter with unbiased pore distribution?
    Performance of a filter with an unbiased pore distribution ( α = 0, N top = N bottom = 100 and N int = 500) and interconnectivity distance d = 18, with particle size a = 0.7 (red dotted), a = 0.8 (blue dashed) and a = 0.9 (black solid).

    How can porosity be controlled indirectly?
    According to the definition of porosity, porosity is the percentage of hole volume to the volume of the outer contour. Therefore porosity can be controlled indirectly by controlling the volume of the part entity as a percentage of the outer contour volume.
