The said apparatus includes a telescopic cigarette holding unit for holding a cigarette which may be retracted into a housing when the apparatus is not in use. The apparatus includes a filtration unit to filter the smoke from the cigarette before being discharged. The apparatus includes one or more fans to introduce fresh air into the housing to allow for the cigarette to burn and also to suck smoke out of the housing. The apparatus also includes an ignition coil to light the cigarette and a wire mesh to trap ash from the burning of the cigarette. The apparatus further includes a valve assembly having one or more one-way exhaling valves for exhaling the smoke out and one one-way for inhaling valve for inhaling the smoke from the burning cigarette because users like resistance when inhaling but not when exhaling. ## Claims ### Claim 1 A cigarette filtration apparatus, comprising: a valve assembly mounted to a housing that includes a filtration unit therein, said housing includes a combustion compartment opening that leads to a combustion compartment, said housing also includes a filtration compartment, said combustion compartment receives a tube that is mounted to said valve assembly, said filtration compartment includes said filtration unit, said combustion compartment includes a heating element, said valve assembly has a bottom end that is secures a cigarette having a tip and a butt, said bottom end secures said butt, said heating element is raised within said combustion compartment a height sufficient to light the tip of said cigarette, said heating element is powered by a battery located within said housing, and a fan located within said housing, said valve assembly includes a top end and a bottom side, said top end includes a top channel that leads to an inhaling valve, said top channel receives a mouthpiece, said bottom end includes a cigarette channel that receives the butt of said cigarette, said cigarette channel travels within said valve assembly, at least one exhaling valve mounted, adjacent said cigarette channel. ### Claim 2 (depends on 1) The filtration unit of claim 1 including an upper and a lower filtration unit. ### Claim 3 (depends on 2) The filtration unit of claim 2 wherein said upper or lower filtration unit is made of activated carbon and said upper or lower filtration unit is made of fiber material. ### Claim 4 (depends on 1) The housing of claim 1 having a bottom that includes filtration escape openings adapted to allow filtered air to be suctioned by said fan. ### Claim 5 (depends on 1) The housing of claim 1 wherein said battery is hermetically sealed within said housing in its own compartment. ### Claim 6 (depends on 1) The valve assembly of claim 1 wherein said inhaling valve cooperates with an inhaling valve flapper and said exhaling valves work with corresponding exhaling valve flappers. ### Claim 7 (depends on 1) The valve assembly of claim 1 wherein said top channel travels between said inner side walls, at least one orifice located along said inner side walls located adjacent to said top channel that cooperate with said exhaling valves. ### Claim 8 (depends on 1) The valve assembly of claim 1 wherein said tube is mounted to said valve assembly using a tube attachment portion located adjacent to said cigarette channel. ### Claim 9 (depends on 1) The cigarette filtration apparatus of claim 1 wherein at least two fans are located within said housing. ### Claim 10 (depends on 1) The cigarette filtration apparatus of claim 1 wherein said heating element is an ignition coil. ### Claim 11 (depends on 1) The cigarette filtration apparatus of claim 1 wherein a removable wire mesh is positioned under said heating element configured to catch ash and debris that falls from said cigarette. ### Claim 12 (depends on 1) The cigarette filtration apparatus of claim 1 wherein said tube is telescopic and said combustion compartment is long enough to completely house said tube. ### Claim 13 (depends on 1) The cigarette filtration apparatus of claim 1 wherein said heating element is raised within said combustion compartment a height sufficient to light the tip of said cigarette using a support column. ### Claim 14 (depends on 13) The cigarette filtration apparatus of claim 13 wherein said tube has a first diameter and said support column has a second diameter, wherein said first diameter is greater than said second diameter. ### Claim 15 (depends on 1) The cigarette filtration apparatus of claim 1 wherein said tube includes an O-ring adapted to keep said tube supported and sealed within said combustion compartment. ### Claim 16 (depends on 1) The cigarette filtration apparatus of claim 1 wherein said inhaling and exhaling valves are one-way valves. ### Claim 17 (depends on 1) The cigarette filtration apparatus of claim 1 wherein said valve assembly includes an inhaling valve that is configured to be disposed in a closed position when a user exhales into said tube through a mouthpiece, said valve assembly includes exhaling valves that are configured to being disposed in an open position when said user exhales into said tube using said mouthpiece. ### Claim 18 (depends on 1) The cigarette filtration apparatus of claim 1 wherein a level of resistance to a user inhaling or exhaling through said tube is adjusted by adding more or less inhaling or exhaling valves. ### Claim 19 (depends on 1) The cigarette filtration apparatus of claim 1 wherein said housing includes a step therein that provides access between the combustion compartment and the filtration compartment.
