Device and method for containing and filtering exhaled smoke

摘要

A device and method for containing and filtering exhaled smoke. When a smoker exhales smoke into the mouthpiece, the smoke is initially stored in a bag or bellows. Pressure on the bag or bellows, provided by the material itself, gravity, or a spring, forces the smoke through a filter before being released into the surrounding air.
