This isn't necessarily a direct answer to your question, but in my pickup, I use a Csonka Smoker Cloaker. I turn it on during the blessed event, and let it run about 24 hours afterward. Very effective. They have other lines available for the home in different sizes. If you live in California, you will have to be...mmm...creative...in getting one, as the tree huggers get all spastic when you mention the words 'ozone generator'...
