The air filter assembly includes a body having a bracket and a frame. The bracket is configured to mount to a bicycle frame. The frame defines a tapered opening having a windward side and a leeward side. The tapered opening is larger on the windward side than on the leeward side. A removable air filter cartridge is mounted within the opening of the frame such that a force acting on the air filter cartridge on the windward side tends to wedge the air filter cartridge in the opening. A foam member is attached to an outer periphery of the air filter cartridge and is disposed between the air filter cartridge and the frame. The foam member is compressible so as to hold the air filter cartridge in the opening of the frame. The foam member compresses to a greater degree on the leeward side of the opening than on the windward side of the opening. The air filter assembly is mountable to a handle bar of a bicycle. ## Claims ### Claim 1 An air filter assembly, comprising: a body having a bracket and a frame, the bracket constructed and arranged to mount to a bicycle, the frame defining a tapered opening having a windward side and a leeward side, the tapered opening being larger on the windward side than on the leeward side; and, a removable air filter cartridge mounted within the opening of the frame such that a force acting on the air filter on the windward side tends to wedge the air filter in the opening. ### Claim 2 (depends on 1) The air filter assembly of claim 1, further comprising a foam member disposed between the air filter cartridge and the frame, the foam member being compressible so as to hold the air filter cartridge in the opening of the frame. ### Claim 3 (depends on 2) The air filter assembly of claim 2, wherein the foam member is attached to an outer periphery of the air filter cartridge. ### Claim 4 (depends on 2) The air filter assembly of claim 2, wherein the foam member compresses to a greater degree on the leeward side of the opening than on the windward side of the opening. ### Claim 5 (depends on 1) The air filter assembly of claim 1, wherein the air filter cartridge includes a first side and a second side, the first side of the air filter cartridge including a filter membrane and the second side of the air filter cartridge including activated carbon, the air filter cartridge being mounted into the opening such that the first side of the air filter cartridge is positioned on the windward side and the second side of the air filter cartridge is positioned on the leeward side. ### Claim 6 (depends on 1) The air filter assembly of claim 1, wherein the tapered opening is round and has a first diameter on the windward side and a second diameter on the leeward side, the first diameter being greater than the second diameter. ### Claim 7 (depends on 1) The air filter assembly of claim 1 wherein the bracket includes a first bracket piece integrally mounted to the frame and a second bracket piece fastenable to the first bracket piece. ### Claim 8 (depends on 7) The air filter assembly of claim 7, wherein the first bracket piece and the second bracket piece define a hinge end, the hinge end being constructed and arranged to allow the second bracket piece to move relative to the first bracket piece. ### Claim 9 (depends on 8) The air filter assembly of claim 8, wherein the hinge end is constructed and arranged to allow the second bracket piece to be removed from the first bracket piece. ### Claim 10 (depends on 9) The air filter assembly of claim 9, wherein the first bracket piece and the second bracket piece define a fastener end, the fastener end being constructed and arranged to receive a removable fastener. ### Claim 11 (depends on 1) The air filter assembly of claim 1, wherein the air filter assembly is mountable to a handle bar of a bicycle. ### Claim 12 (depends on 11) The air filter assembly of claim 11, wherein the air filter assembly is mountable to the handle bar of the bicycle such that the frame is positioned downward. ### Claim 13 An air filter assembly, comprising: a body having a bracket and a frame, the bracket constructed and arranged to mount to a bicycle, the frame defining a tapered opening having a windward side and a leeward side, the tapered opening being larger on the windward side than on the leeward side; a removable air filter cartridge mounted within the opening of the frame such that a force acting on the air filter cartridge on the windward side tends to wedge the air filter cartridge in the opening, wherein the air filter cartridge includes a first side and a second side, the first side of the air filter cartridge including a filter membrane and the second side of the air filter cartridge including activated carbon, the air filter cartridge is mounted into the opening such that the first side of the air filter cartridge is positioned on the windward side and the second side of the air filter cartridge is positioned on the leeward side;
