Abstract
An apparatus, system and method to facilitate fluid flow across a filter. The apparatus includes a filtration layer coupled to a support layer to form a composite filter. The support layer includes a hydroentangled cellulosic material forming a plurality of apertures. The apertures form channels to facilitate fluid flow across the filter while the support layer provides structural support to the filtration layer to enable lateral flow while preventing pleat deformation and collapse.
