The present invention provides a cigarette smoke filtration apparatus. 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.
