1. A reduced-pressure treatment system comprising: a reduced-pressure canister comprising: a basin,a lid configured to mate with the basin to form a fluid reservoir, the lid having a plurality of apertures formed within, and integral with, an exit wall of the lid, each aperture extending through the exit wall of the lid and being in fluid communication with the fluid reservoir,an inlet for receiving fluids from a patient, the inlet in fluid communication with the fluid reservoir, anda hydrophobic coating applied to the plurality of apertures;a reduced-pressure source fluidly coupled to the fluid reservoir through the plurality of apertures; anda reduced-pressure delivery conduit fluidly coupled to the inlet for delivering fluids from the patient to the reduced-pressure canister. 2. The system of claim 1, wherein the plurality of apertures comprise a plurality of pores having a diameter in between about 0.5 and about 1 micron. 3. The system of claim 1, wherein the hydrophobic coating comprises a fluorocarbon. 4. The system of claim 1, wherein the hydrophobic coating comprises a coating selected from a group consisting of heptadecafluorodecylacylate, acrylates containing haloalkyl groups, acrylates containing perhaloalkyl groups, hexamethyldisiloxanes, and 1,2-epoxy-3-phenoxy-propane. 5. The system of claim 1, further comprising an anti-microbial coating over the plurality of apertures. 6. The system of claim 1, further comprising an anti-bacterial coating over the plurality of apertures. 7. The system of claim 1, further comprising a protease coating over the plurality of apertures. 8. The system of claim 1, further comprising a charcoal coating over the plurality of apertures. 9. The system of claim 2, wherein the plurality of apertures have a breakthrough pressure of about 500 mm Hg. 10. A reduced-pressure canister comprising: a basin;a lid comprising a plurality of apertures, the lid configured to mate with the basin to form a fluid reservoir in fluid communication with each of the plurality of apertures formed within, and integral with, an exit wall of the lid, each aperture extending through the exit wall of the lid;an inlet fluidly coupled to the fluid reservoir for receiving fluids from a patient; anda hydrophobic coating applied to the plurality of apertures. 11. The reduced-pressure canister of claim 10, wherein the plurality of apertures comprise a plurality of pores, each pore having a diameter of about 0.5 to about 1 micron. 12. The reduced-pressure canister of claim 10, wherein the plurality of apertures comprise a plurality of parallel slits. 13. The reduced-pressure canister of claim 12, wherein the plurality of parallel slits comprise a first plurality of parallel slits, the reduced-pressure canister further comprising: a grate member having a second plurality of parallel slits, the grate member having a hydrophobic coating; andwherein the grate member couples to the lid over the first plurality of parallel slits so that the second plurality of parallel slits substantially overlies and is perpendicular to the first plurality of parallel slits. 14. The system of claim 1, wherein the plurality of apertures comprise a plurality of parallel slits. 15. The system of claim 14, wherein the plurality of apertures further comprise: the plurality of parallel slits being a first plurality of parallel slits;a grate member having a second plurality of parallel slits, the grate member having a hydrophobic coating; andwherein the grate member couples to the lid over the first plurality of parallel slits so that the second plurality of parallel slits substantially overlies and is perpendicular to the first plurality of parallel slits. 16. The system of claim 1, wherein the plurality of apertures comprise a plurality of micro-holes. 17. The system of claim 1, wherein each micro-hole of the plurality of micro-holes has a diameter between about 0.25 and about 1 micron. 18. The canister of claim 10, wherein the plurality of apertures comprise a plurality of micro-holes. 19. The canister of claim 10, wherein each micro-hole of the plurality of micro-holes has a diameter between about 0.25 and about 1 micron.
