"Flair" makes an excellent combo ozone generator/ionizer. 1 unit will cover a small home and will easily handle a grow room. They are kind of expensive but at the cost of about an oz of fine bud you can own one of these and not worry about the aroma's escaping from the room any more. I've had mine for 3 years now and it's still on the job...easy maintinence too.
