Claim 20:
21. A filtration device for filtering a fluid, comprising:
a first barrier member having a plurality of openings through which the fluid can penetrate the first barrier member, the first barrier member having a plurality of edges including a first edge;
a second barrier member having a plurality of openings through which the fluid can penetrate the second barrier member, the second barrier member having a plurality of edges including a first edge; and
an ion-dispersing thread in the first barrier member,
wherein the first barrier member and the second barrier member are in an overlay relationship relative to each other such that the fluid penetrating one of the plurality of openings in the first barrier member penetrates one of the plurality of openings in the second barrier member,
the first barrier member is at least one selected from the group consisting of: a filtering screen, a porous membrane, a porous film, a fluid permeable mat, and an air permeable mat,
the second barrier member is at least one selected from the group consisting of: a filtering screen, a porous membrane, a porous film, a fluid permeable mat, and an air permeable mat,
a portion of the ion-dispersing thread extends in a direction,
the direction is non-parallel to the first edge of the first barrier member, and
the direction is non-perpendicular to the first edge of the first barrier member.
