ABSTRACT:
A first stream of contaminated air containing solid impurities including reusable tobacco particles is exhausted from a machine for the making of smokers' products and is caused to pass first through a first filter which separates therefrom all of the impurities, and the thus decontaminated air is caused to pass through a cooler and back to the machine. The separated impurities are caused to pass through a second filter which segregates therefrom the reusable tobacco particles, and such particles are reintroduced into the machine. The first stream of contaminated air can receive a second stream of contaminated air from a second machine, and such second stream is introduced into the first stream ahead of the first filter.
