1. A porous media assembly for controlling air passing therethrough, the porous media assembly comprising: a housing comprising a cavity formed therein, wherein the housing is disposed within an aperture of an enclosure, wherein the enclosure is suitable for potentially explosive environments, and wherein the housing and the enclosure are configured to form a flame path where the housing and the enclosure join;a porous media positioned within the cavity and coupled to the housing; anda reinforcement structure coupled to an end of the housing and adjacent to a top end of the porous media. 2. The porous media assembly of claim 1, wherein the housing further comprises an exterior surface, wherein the exterior surface comprises threads for mating with corresponding threads disposed on a perimeter of the aperture of the enclosure. 3. The porous media assembly of claim 2, wherein the porous media comprises sintered material. 4. The porous media assembly of claim 1, wherein the porous media has a density sufficient to allow at least 0.01 cubic feet per minute of the air to pass through. 5. The porous media assembly of claim 1, wherein the reinforcement structure comprises at least one rib extending inward from a perimeter of the reinforcement structure towards a center of the perimeter along the top end of the porous media. 6. The porous media assembly of claim 5, wherein the at least one rib comprises at least one contact point in contact with the top end of the porous media. 7. The porous media assembly of claim 6, wherein the at least one rib further comprises at least one elevated portion adjacent to the at least one contact point, wherein the at least one elevated portion creates an air gap between the top end of the porous media and the at least one rib. 8. The porous media assembly of claim 5, wherein at least two ribs are joined at the center of the perimeter of the reinforcement structure by a boss, wherein the boss is configured to facilitate rotational movement of the porous media assembly. 9. The porous media assembly of claim 8, wherein the boss is further configured to receive a fastening device, wherein the fastening device couples a shroud to the porous media assembly, wherein the shroud is configured to cover portions of the porous media assembly that are external to the enclosure. 10. The porous media assembly of claim 1, wherein the porous media comprises a bottom end, wherein the bottom end of the porous media is coupled to an inner surface of the housing in the cavity. 11. The porous media assembly of claim 10, wherein the porous media is coupled to the inner surface of the housing in the cavity by at least one selected from a group consisting of welding, using epoxy, brazing, press fitting, mechanically connecting, threading, using a flat joint, and using a serrated joint. 12. The porous media assembly of claim 1, wherein the reinforcement structure is welded to the housing. 13. The porous media assembly of claim 1, wherein the reinforcement structure includes at least one notch for draining fluid from the top end of the porous media, wherein the at least one notch is located along a perimeter of the reinforcement structure. 14. The porous media assembly of claim 1, wherein the reinforcement structure is constructed of a material selected from at least one of a group consisting of steel, aluminum, plastic, and an alloy metal. 15. The porous media assembly of claim 1, wherein the controlling the air passing through the porous media assembly comprises at least one selected from a group consisting of containing a fire, suppressing a fire, removing dust and other particles from the air, removing moisture from the air, and cooling the air. 16. A method for controlling air passing through a porous media assembly, the method comprising: receiving the air at a first porous media assembly end;passing the air through the porous media assembly to generate controlled air; andpassing the controlled air through a second porous media assembly end,wherein the porous media assembly comprises: a housing comprising a cavity formed therein, wherein the housing is disposed within an aperture of an enclosure, wherein the enclosure is suitable for potentially explosive environments, and wherein the housing and the enclosure are configured to form a flame path where the housing and the enclosure join;a porous media positioned within the cavity and coupled to the housing; anda reinforcement structure coupled to a housing end and adjacent to at least one of the porous media ends. 17. The method of claim 16, wherein the housing further comprises an exterior surface, wherein the exterior surface comprises threads for mating with corresponding threads disposed on a perimeter of the aperture of the enclosure, and wherein the porous media comprises sintered material. 18. The method of claim 16, wherein the reinforcement structure comprises at least one rib extending inward from a perimeter of the reinforcement structure towards a center of the perimeter along the at least one of the porous media ends, wherein the at least one rib comprises: at least one contact point in contact with the at least one of the porous media ends; andat least one elevated portion adjacent to the at least one contact point, wherein the at least one elevated portion creates an air gap between the at least one of the porous media ends and the at least one rib. 19.
