Making sure I am smell proof

The neighbour said something today that terrified me at first, saying there was a strange smell in their attic that she couldn't seem to get rid of. Their house has been recently renovated (six months ago) and I suspect it is new carpets or something like that. She can't identify it, just says it's strange, goes away for a bit when she vacuums with carpet freshener but comes back eventually.

Now, logic tells me it almost certainly isn't me, but I worry nonetheless. I am venting into the chimney on the other side of the house from the join with this particular neighbour, but I worry it might be seeping through brickwork or whatever. Could I just be "immune" to the smell? Are there any tips out there for checking for smelly-proof-ness?

I almost certainly am being paranoid over nothing, but better safe than sorry.

Also, I plan on getting some ONA gel to put in a bowl and place in the exhaust ducting to double-up my odour control (in addition to carbon filter). Does anyone know if the fresh linen gel actually smells like fresh linen? I am using ONA Pro at the moment but it smells WEIRD and something a little more natural would be good.

Thanks in advance.

Negative pressure pulled through a carbon filter, thru fan, then inline ozone generator, then minimum 20 ' of duct and then exhausted out a roof vent. You could also toss a scrubber setup in the room to help cut the odor.

You do get used to the smell living with it.

What he said... ^

Carbon filter and a fan and you got 99 problems but odor an't one.

you need to measure your room and get the cubic feet per meter then buy a fan and carbon filter to go along with it and create negative pressure like snapsprovolone said. the way it works is that all the air leaving the room gets pushed through that so the smell cant escape any where else since its all being sucked through the fan and pushed out through the filter.

Already got the carbon filter and inline fan and negative pressure, but it's not always 100% effective, when humidity has been high, it is letting a lot of smell through. Ozone is a very expensive option that leaves a telltale smell of its own, two reasons I'd like to avoid it if possible.

Regarding the 20' of ducting, what's the reason for this please? I'd always heard you should have as short a ducting as possible to minimize the strain on the fan?

Do you mean a second carbon filter with inline fan attached inside the tent, or something else, please Snaps?

20' is minimum for post inline ozone generator to allow o3 time to do it's work. A few bends really help mix. I'm pulling off several 8" hoods with inline ozone and no cf, there is no skunk smell outside the vent.

Scrubber is a fan on a carbon filter just recirculating room air.

Ok thanks, so i guess go for the long duct if I end up with o3, otherwise keep it as short as poss.

I do have a spare carbon filter as I upgraded, but not a spare inline fan alas.
