carbon filter or no carbon filter???

Hi guys Iâ??m new around here and just wanted some advise on my 1st grow before I start to flower. I have a small front of the house witch I have a grow closet in I keep the door/window closed and have stuck a double mattress over the window so that no heat or smell will leave the room.

I have 3 plants that are about 8 weeks old they are skunk no 1 so will pong a bit me thinks lol i am useing cfls so no heat worrys. I have uploaded a layout of the top floor of my flat that is on the 2nd floor and i have the 1st and 2nd floors but have a shop that is open 9-till 5 under me.

I have no real ventilation just to big pc case fans in the back of the closet and i was thinking on installing a short bit of ducting that will connect the exsorst fan to a carbon filter but i was just wondering is there much point in pumping air out though my carbon filter into a small room? i could install an extra bit of ducting to then take it from the filter out though the roof but not sure if that is over kill for just 3 plants? I was also going to invest in some air fresheners and possible some of them ona gel pot things

Any advise will be appreciated thanks

Just mount the carbon filter inside the room and let it continuosly recycle the air in the room rather than venting it outside.

thank you very much for your replay i was thinking that was the best idea jsut wanted a second opinion thanks again
