Kent (1 mg / Charcoal Filter) /KS-20-H/ - USA
This brand prides itself to be able to claim a minimal 1mg of tar from each cigarette, (depending on how you smoke it of course), through the use of an innovative charcoal filter that is much better at absorbing excess Carbon Monoxide and tar.
However, the Carbon Monoxide is not as high as some brands who have adopted placing prosthetic Haemaglobin within the filter, which absorbs nearly all the Carbon Monoxide, but then you're left with the tar. It's one or the other, until or course we get 'Double Filter' Brands, it's a matter of time.
