Alternative to a carbon filter?

Okay first of all I'm not going to jail for 2 or 3 plants. Its canada. Also I don't want any pointless comments like using my bathroom fan for exhaust that's just stupid. And like I said before I can't use a carbon filter it just can't be done. I called my local hydroponics store today and they have ONA and something else to remove smell. I'm gona cheak it out soon and post again peace,

you don't need to vent out the exhaust....just use a carbon filter to scrub the air...just hook up the fan right to the filter and it just recycles the air in the room

problem solved read your replys more carefully.. you dont need to vent the air out of your closet just vent it period.

Got one of these. Not perfect but close. It's a scrubber and requires no outside venting. $$$ though.
