Electronic Portable Air Conditioner

Which portable air conditioners do not exchange air with the room? strictly circulate and cool it?

If one is smoking a cigarette, and doesnt want to disturb the roommate, which portable air conditioner will be perfect? looking for one that will not exchange air in the room, and keep the dual hoses strictly for cooling the condensor. which brands do so? if anyone has one, do a ?smoke test" for me, blow into the front vents, and see if any smoke goes through to the two hoses on the back somehow. lots do so wondering which are actually seperate...

1. They all have the ability to use Room air, or exhaust- Room air will cool better, look for the switch.
2. You have to exhaust the hot air outside or to another room other wise your just putting the heat from the cooled air back into the room.
3. Don't Smoke and you won't have to worry about it! An added bonus is all the money you will save by not purchasing tobacco products
