Abstract
Disclosed is a porous device adapted to remove particulates from a fluid passed through the device. The device includes a porous filtration medium. The medium has a first surface having an area which is adapted to receive the fluid for passage through the medium and a second surface from which the fluid exits the medium. The device is configured to variably increase the area of the first surface in response to a differential in fluid pressure between the first surface and the second surface so as to extend the life of the device. In some embodiments the device is adapted to retain the increase in surface area which acts as a visual indication that the device is reaching its capacity to retain particulates.
