The cannister as claimed in claim 3, said internal chamber being generally cylindrical in shape, said tube being generally centrally located within the cylindrical internal chamber. 5. The cannister as claimed in claim 4, said wall presenting at least one drainage aperture formed therein. 6. The cannister as claimed in claim 5, said at least one drainage aperture being positioned in the wall adjacent the first end panel. 7. The cannister as claimed in claim 3, said absorbent core being located within the internal chamber between the wall and the tube and extending between the end panels. 8. The cannister as claimed in claim 1, said absorbent core being formed of an oil-specific sorbent particulate. 9. The cannister as claimed in claim 8, said sorbent particulate being operable to absorb at least tenfold its own weight in grease. 10. The cannister as claimed in claim 1, said coupling mechanism including a flexible member pivotal between a retention position and removal position when the cannister is coupled to the fan, said member forming a first angle relative to horizontal when in the retention position, said member forming a second angle relative to horizontal when in the removal position, said first angle being more acute than said second angle. 11. The cannister as claimed in claim 10, said coupling mechanism being dimensioned and configured so that when the cannister is coupled to the fan the coupling mechanism is slidably removable from the fan when the flexible member is in the removal position and generally prevented from being removed from the fan when the flexible member is in the retention position. 12. The cannister as claimed in claim 11, said flexible member being fixed relative to the cover. 13. The cannister as claimed in claim 11, said coupling mechanism further including a locking pin removably coupled relative to the flexible member when the cannister is coupled to the fan so that when the pin is coupled relative to the flexible member, the coupling mechanism is generally prevented from being slidably removed from the fan. 14. The cannister as claimed in claim 1, said cover being threadably coupled to the receptacle. 15. A ventilation assembly comprising: an exhaust fan including an impeller operable to generate an airstream, a shroud operable to separate any fluid in the airstream from the airstream when the airstream engages the shroud, and a fluid conduit in fluid communication with the shroud; and a disposable fluid collection cannister for collecting the fluid separated from the airstream generated by the exhaust fan including a container, a fluid absorbent core, and a coupling mechanism, said container including an open-top receptacle that presents an internal chamber adapted to contain fluid, said container further including a cover that at least substantially covers the open-top of the receptacle, said container presenting a fluid access opening in fluidic communication with the fluid conduit when the container is coupled to the fan, said fluid absorbent core being located within the chamber of the receptacle, said coupling mechanism operable to couple the container to the fan and permit manual removal of the container from the fan without contacting the receptacle, said coupling mechanism being adapted to non-threadably couple the container to the fan so that the container is coupled to and removed from the fan without twisting. 16. The ventilation assembly as claimed in claim 15, said fluid conduit comprising a fluid collection surface generally located at the bottom of the shroud and an aperture defined in the shroud generally adjacent the surface and fluidly co mmunicating with the fluid access opening and the surface. 17. The ventilation assembly as claimed in claim 16, said coupling mechanism including a flexible plate slidably received in and slidably removed from the aperture in the shroud. 18. The ventilation assembly as claimed in claim 17, said plate including a flange that engages the inside surface of the shroud when the plate is slidably received in the aperture in the shroud to generally prevent slidable removal of the coupling mechanism from the shroud. 19. The ventilation assembly as claimed in claim 18, said plate pivotal into and out of a removal position wherein the flange is disengaged from the inside surface of the shroud to generally permit slidable removal of the coupling mechanism from the shroud when the plate is received in the aperture in the shroud. 20. The ventilation assembly as claimed in claim 19, said plate biased out of the removal position when the coupling mechanism is received in the aperture in the shroud. 21. The ventilation assembly as claimed in claim 18, said plate further including a cover section extending opposite the flange, said cover section of the plate being fixed relative to the cover of the container. 22. The ventilation assembly as claimed in claim 17, said fluid conduit including a trough fluidly communicating the surface with the fluid access opening via the aperture, said trough including a pair of spaced apart trough walls extending from the opposite sides of the aperture. 23. The ventilation assembly as claimed in claim 22, said coupling mechanism further including a pair of spaced apart sidewalls extending between the plate and the cover and being configured to receive the trough walls therebetween. 24. The ventilation assembly as claimed in claim 23, each of said sidewalls being fixed relative to the cover and dimensioned to space the container from the surface so that the chamber is at least in part positioned below the surface when the cannister is coupled to the fan. 25. The ventilation assembly as claimed in claim 23, said coupling mechanism further including a locking pin removably received through the sidewalls and the trough walls so that when the pin is received therein, the coupling mechanism is generally prevented from being slidably removed from the aperture in the shroud. 26. A disposable fluid collection cannister for collecting fluid separated from the airstream generated by an exhaust fan, the cannister comprising: a container including a receptacle that presents an internal chamber, with the chamber being adapted to contain fluid and being in fluidic communication with the fan when the container is coupled to the fan; a fluid absorbent core located within the chamber of the receptacle; and a coupling mechanism operable to couple the container to the fan and permit manual removal of the container from the fan without contacting the receptacle, said coupling mechanism including a manually shiftable retention catch that is shiftable between a retention position in which the catch is operable to engage the fan and thereby retain the container on the fan, and a release position in which the catch is disengaged from the fan and permits removal of the container from the fan. 27.
