1. A filter assembly comprising: a housing; anda filter held within the housing, the filter comprising: a spacing member; anda filter element comprising two layers laminated together with the spacing member such that the spacing member extends between the filter element layers, wherein the spacing member spaces apart the filter element layers to define an opening between the filter element layers, the opening comprising an end, the spacing member defining a boundary at the end of the opening that closes the end of the opening. 2. The filter assembly according to claim 1, wherein the filter element layers are spaced apart by the spacing member approximately the same amount along an approximate entirety of opposing surfaces of the filter element layers. 3. The filter assembly according to claim 1, wherein the filter element layers extend approximately parallel to each other. 4. The filter assembly according to claim 1, wherein each of the filter element layers extends a length along an approximately spiral path. 5. The filter assembly according to claim 1, wherein the filter comprises one of a circular filter, a rectangular filter, and a radial flow filter. 6. The filter assembly according to claim 1, wherein the spacing member comprises at least one of an adhesive, an adhesive tape, an adhesive string, and an adhesive plastic. 7. The filter assembly according to claim 1, wherein the end of the opening is an intake end, the opening further comprising a discharge end, the opening being configured to discharge fluid that has traveled through one of the filter element layers through the discharge end. 8. The filter element assembly according to claim 1, wherein the filter element layers are first and second filter element layers, the opening is a first opening, and the spacing member is a first spacing member, the filter further comprising a second spacing member, the filter element further comprising a third layer, the first, second, and third filter layers being laminated together with the first and second spacing elements such that the second spacing element extends between the second and third filter element layers, wherein the second spacing member spaces apart the second and third filter element layers to define a second opening between the second and third filter element layers, the first and second openings comprising intake ends and discharge ends, the first spacing member forming a boundary at the intake end of the first opening that closes the intake end of the first opening, the second spacing member forming a boundary at the discharge end of the second opening that closes the discharge end of the second opening. 9. The filter element assembly according to claim 1, wherein one of the filter element layers has opposite first and second edge portions, the spacing member being a first spacing member comprising a strip of material that extends a length along the first edge portion, the filter comprising a second spacing member comprising a strip of material that extends a length along the second edge portion. 10. A filter comprising: first and second spacing members; anda filter element comprising first, second, and third layers extending approximately parallel to each other, the first, second, and third filter element layers being laminated together with the first and second spacing members such that the first spacing member extends between the first and second filter element layers and the second spacing member extends between the second and third filter element layers, wherein the first spacing member spaces apart the first and second filter element layers to define a first opening between the first and second filter element layers, and the second spacing member spaces apart the second and third filter element layers to define a second opening between the second and third filter element layers, the second filter element layer comprising opposite first and second edge portions, the first spacing member extending adjacent the first edge portion of the second filter element layer, the second spacing member extending adjacent the second edge portion of the second filter element layer. 11. The filter according to claim 10, wherein the second filter element layer is inverted relative to the first filter element layer and relative to the third filter element layer. 12. The filter according to claim 10, wherein the first and second openings comprise intake ends and discharge ends, the first spacing member forming a boundary at the intake end of the first opening that closes the intake end of the first opening, the second spacing member forming a boundary at the discharge end of the second opening that closes the discharge end of the second opening.
