Zinsser or Kilz for Cigarette smoke

[Prachi Metha]

My newly purchase house has a Cigarette smoke from the previous owner. Ozone treatment and duct cleaning is done, it helped but still smoke is there. Next step is I am moving to get house paint with Zinsser or Kilz primer. Can someone point me extact product I should look into since there are many version of it. I could Kilz Restoration Interior Primer but not sure if this is going to work or should I look into Zinsser. Please advice.

@Prachi Metha - I recently took ownership of a home with the same issue. My contractor did the work. As @Rick Albert mentioned, we wiped down EVERYTHING with TSP. We also had the ducts cleaned, replaced carpeting, replaced blinds (they were yellow from the smoke), and then painted. I think he used Kilz primer, although he may have cut a corner there, to be honest. In the end, the smoke smell was gone. Although we talked about it we never used or needed the Ozone machine.
