Abstract

Abstract An adjustable tobacco smoke filter device for attachment to cigarettes, cigars and the like has a filter body with an internal passage and a mouthpiece with a similar internal passage. The mouthpiece has one end disposed adjacent the filter body with the internal passages in aligned relationship. Advantageously the mouthpiece is mounted for manual rotation relative to the filter body. A filter wrapper of resilient material is provided with a compressible tobacco smoke filter material disposed therein. The resilient filter wrapper is open at opposite ends and provides a smoke passage for tobacco smoke through the filter material. The filter wrapper is disposed in the internal passages of the filter body and the mouthpiece with one end fixed to the filter body and with its opposite end fixed to the mouthpiece. Upon manual rotation of the mouthpiece the filter wrapper is twisted to restrict the smoke passage therethrough.
