Multi stage smoke filtration device

Abstract

A filtration apparatus and method used for the inhalation of smoke that is created from burning substances in a water pipe or similar, useful for reducing the harshness of smoke, removing toxins from smoke and flavoring smoke. A two stage filtration apparatus originates with a mouthpiece adapted to seal off the opening of the inhalation tube of a typical water pipe. A first stage tubular filter housing is attached to the bottom end of the mouthpiece located inside the inhalation tube. A second stage tubular filter housing is attached to the bottom of the first stage housing. Smoke passes into the second stage housing and through circular second stage then first stage disposable filter medium packets held into place by the filter housings. A method of pressing the lips against the mouthpiece portion seals off the inhalation tube opening and frees both of the user's hands so that one hand can support the water pipe while the other ignites and reignites the burned substance.

1 . A mouthpiece portion of sufficient size to allow the lips of the mouth to form a seal around its top end. 
     
     
         2 . The mouthpiece portion of  claim 1  comprising a means for sealing off the opening of the inhalation tube portion of a typical water pipe or similar, said means including but not limited to a conical surface of sufficient size and pitch such that its largest and smallest circumferences allow for said conical surface to seat said mouthpiece portion partially outside and partially inside said inhalation tube opening such that said top end of said mouthpiece is seated outside of said inhalation tube opening and the bottom end of said mouthpiece is seated inside said inhalation tube opening, said bottom end having threading on its outer surface. 
     
     
         3 . A method for keeping said mouthpiece held tightly against said inhalation tube opening without use of the user's hands comprising pushing said lips of the mouth against said mouthpiece such that said mouthpiece is thereby pressed against the inner circumference of said inhalation tube opening. 
     
     
         4 . The device according to  claim 1  including a first filtration housing comprising a tube with internal threading on its top and bottom ends, each set of said internal threads terminating internally in a filter support ring and each set of said internal threads being of a corresponding pitch to said external threads of said mouthpiece portion. 
     
     
         5 . The filter support ring of  claim 4  comprising a circular protrusion extending inwardly from the inner circumference of said first filtration housing such that a filter support disc can be placed against it. 
     
     
         6 . The filter support disc of  claim 5  comprising a disc of sufficient circumference such that it can be inserted into said first filtration housing and be held into place by said filter support ring and comprising a plurality of small perforations. 
     
     
         7 . The filter support disc of  claim 5  comprising a disc of sufficient circumference such that it can be inserted into the opposite end of said first filtration housing from which the filter support disc of  claim 6  has been inserted and be held into place by said filter support ring and comprising a plurality of small perforations. 
     
     
         8 . A second filtration housing comprising a tube with external threading on its top end, said threading being of a corresponding pitch to the internal threading of said first filtration housing. 
     
     
         9 . The mouthpiece portion bottom end of  claim 2  comprising a sufficient size and shape with which to crimp the outer circumference of a circular filtration medium packet against said filter support. 
     
     
         10 . The second filtration housing top end of  claim 8  comprising a sufficient size and shape with which to crimp the outer circumference of a circular filtration medium packet against said filter support.
