ABSTRACT:
Disclosed is a smoker's module for isolating, containing, venting, and filtering tobacco smoke with a self-contained expandable modular structure adapted for use as both a freestanding unit and as an addition within an existing structure. The smoker's module comprises a plurality of joinable panel assemblies forming a tobacco smoke isolating enclosure having a plurality of walls, a roof, and at least one sealable user entry door. The panel assemblies each comprise a metal frame having a gasketed transparent safety glass panel mounted therein. A plurality of intake vent apertures extend through panel assembly frames proximal the floor. An exhaust vent aperture, having an electrically powered fan mounted therein, causes fresh air to be drawn into the enclosure through the intake apertures while tobacco smoke-laden air is simultaneously expelled through the exhaust vent aperture. The exhaust aperture also has a porous filter element mounted therein whereby tobacco smoke particles are removed and retained prior to the air being released outside the enclosure.
