A filter and replaceable filter leaf apparatus are provided. The filter includes a housing defining a cavity having fluid inlet and outlet ports and a lid member with a manifold coupled to the outlet port and being adapted to conduct a fluid flow between the outlet port and a plurality of attachment areas. Replaceable filter leafs are selectively movable through an opening into the housing cavity and attachable with the manifold at the plurality of attachment areas. The replaceable filter leafs include a filter envelope consisting of a single substantially rectangular filter panel, a nozzle member on the filter panel and defining a passageway adjacent an opening in the filter envelope for conducting fluids therethrough, and a porous grid member contained within the filter envelope. The nozzle member is selectively attachable onto the manifold of the polishing filter apparatus at one of the plurality of attachment areas. In one form, the filter envelope includes a folded rectangular filter panel with the nozzle member disposed at an outer edge thereof. In another embodiment, the nozzle member is located at a crease line formed in the filter panel. In yet another, a pair of filter panels are connected at their edges with the nozzle member located along a selected edge as desired. The filter leaf apparatus are installed onto the manifold along attachment axes extending through the housing opening.

The invention claimed is: 1. A replaceable filter leaf apparatus for use in an associated filter system including a housing having a cavity with fluid inlet and outlet ports for conducting a flow of fluids into and out from the housing and having a manifold operatively coupled with the outlet port, the filter leaf apparatus comprising:a drainage grid member defining a plane and comprising at least one channel for directing a fluid to flow in one or more directions substantially parallel with the plane defined by the drainage grid member;a porous filter media disposed adjacent the drainage grid member for filtering the fluid entering the grid member; and,a nozzle adapter member operatively coupled with the drainage grid member and the porous filter media, the nozzle adapter member defining an elongate passageway for conducting fluids therethrough along a first direction within the nozzle adapter member, the nozzle adapter member adapting the filter leaf apparatus for selective slidable connection with the manifold of the associated filter system in a second direction substantially perpendicular to the first direction, wherein a sealing portion of the nozzle adapter member is configured to generate a seal in a sealing plane between a margin surface surrounding an outlet of the elongate passageway of the nozzle adapter member and the associated manifold by biasing the nozzle adapter member against the associated manifold along an axis substantially perpendicular to the sealing plane.
