Ok. Maybe I'll have to try it. As I've said before, my Mom is a cancer survivor and still has a very sensitive nose - even after 10+ years. I'd like to be able to use more than my emow and evod
tanks inside since the difference in vapor production is huge between those and my subtank and magma. I'm also trying to filter out some of my Dad's cigar smoke that wafts down the steps from his study to where my computer and TV sit.
