1. A filter element, comprising:

  • a filtration media;

    an upstream filtration media support positioned upstream from and in contact with said filtration media; and

    a multi-layer downstream filtration media support positioned downstream from said filtration media, said multi-layer downstream support including a first downstream support layer and a second downstream support layer, wherein;

    (a) said first downstream support layer is in contact with said filtration media and is interposed between said filtration media and said second downstream layer, said first downstream support layer is fabricated so as to minimize points of surface contact with said filtration media; and

    (b) said second downstream support layer is in contact with said first downstream support layer and is fabricated so as to facilitate lateral fluid flow relative to said multi-layer downstream pleat support.
