How do you make a reflector airtight?

I'm pulling air through the carbon filter, through the reflector, out the tent. Since the reflector is not airtight some air is leaking through and not going through the carbon filter first, allowing odor to escape. What can I do to fix this?
Thanks

Your options are:

1. Use some metal duct tape to seal the reflector (search for REFLECTIX on our website).
2. Relocate the filter to the opposite end of the duct run; i.e. put it outside the room and suck instead of push the air out of the room.
3. Buy a newer reflector. Many of the nicer reflectors we now sell have an improved hinged lid and gasket assembly which greatly reduces or eliminates leakage.
