Soliciting advice:
My neighbor finds my smoking objectionable. We’ve had the vents shut (she says that’s not where the smell is strongest anymore), I have weather-stripping tight around my door, we both had our apartments painted with sealant after spackling all the visible cracks, I have two air purifiers going in my place, she’s got one in hers… we’re both baffled how she can still smell my smoking. The building is a 1960’s high-rise.
Ideas?
