Aw man that's tough. I noticed my neighbour standing in the garden sniffing in the air, so I checked my filter by sticking my nose in the pipe, and it stunk bad enough, so scared me into buying the best biggest filter I could and an in-line ozone generator, and several smaller filters to put around the house, still worries me, but I don't think the smell is any worse now than from what I'm actually smoking, well that's what I'm telling myself anyway :-/
