Smoking Room Ventilation

[Wharf Rat]

It's really meant to be built in, like a ceiling fan. Different models are, well, different and you need to check the specs. This one is 120 V, .7 A, so it could probably be added to most household circuits depending on how much load there already is on the circuit breaker.

I would emphasize the advice above that you need a lot of CFMs to control smoke while you are smoking. The best thing is to choose the number of air changes per hour you want and that leads to the CFM. If you just want something that helps a little bit, then a window fan or the like is sufficient. You always want more air flowing no to the outside because this will keep smoke from migrating into the rest of the house.
