Weed smell capture

That won't do shit. I'll give you the run down on what will actually work and last forever. Go to a hardware store and get a quarter or half inch threaded end metal pipe and some 90 degree connectors to fix to it. Then go to jew mart and in the fish section there is activated carbon for fish filters. Now go home and attach one of the connectors and plug it with cotton. Now the fill the pipe with the carbon and run some water through it to activate the shit. Let the excess water get out of the bitch and connect other connector. Take cotton out of cotton end and replace by stuffing dryer sheets in the ends of both connectors to prevent carbon from falling out and it'll help with an residual smell although there shouldn't be. Blow through the tube. I recommend using a one hitter and clearing it in one hit. Also a wax warmer will make your room smell good and cover up any fuck ups. Replace carbon about once a month.
