Masking emitter

Hello, I have got question about making cigarette smoke. I wish I could make emiter like a “point”, but smoke is around it. This big bulb of smoke at the beggining should not be there, any suggestions how to get rid of it? I tried this torus as a emiter with negative pressure to suck in some smoke, it made it thiner but the issue with emitter is still there.

We released a new update today with emitter smoothness that may help with this. Also using (add (dropdown)) instead of replace for smoke may help in the emission settings.
