Aww that's really bad luck mate, so sorry to hear this :-( result with the caution for that many though. But hope you don't mind me asking, but how did it come on top?
@Dosmokethereefa,
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 :-/
@Jaysee, my stupid complacency runnin a 4x4 and a 3x5 sucking air out both and blowing it thru a 2x2 no carbon filter on to be fair I did know u could smell it 3 doors up, and I live in a detached at that 😆
