I would consider adding a positive pressure to your living space with the fresh air being pulled from a wall on the opposite side of the house. I have installed this type of fan in several multi family-family dwellings to keep smoke stink out. The ones iI have used are quite small squirrel cage-cage blowers that operate with a pressure switchswitch; I think it was based on 2 or 3” water column.

The slight positive pressure pushes air out through light fixtures  , switches and outlets. The only negativedownside I remember: because these are small, if you open a window or door for long you looselose the advantage of the positive pressure. I did a hand fullhandful and put each one in a wall next to an existing outlet so no new circuits needed to be run.

I don’t know if you can really seal things but the positive pressure fan worked. I had 1 customer have me install them Inin 3 different houseshouses; the last one was a single family-family home but she said she liked the fresh air (that house had no make up air electric baseboards) and it made her feel better, so those little positive pressure-pressure fans do work.

The slight positive pressure pushes air out through light fixtures, switches and outlets. The only downside I remember: because these are small, if you open a window or door for long you lose the advantage of the positive pressure. I did a handful and put each one in a wall next to an existing outlet so no new circuits needed to be run.
