Smoke and Odor Elimination Filters, Devices and Methods

Abstract

A pipe comprises a combustion bowl with bowl vents; an inhalation path for drawing smoke from the combustion bowl through the bowl vents during inhalation; an exhalation filter; and an exhalation path for forcing exhaled smoke through the exhalation filter during exhalation.

1 . A pipe, comprising:
 a combustion bowl with bowl vents;   an inhalation path for drawing smoke from the combustion bowl through the bowl vents during inhalation;   an exhalation filter; and   an exhalation path for forcing exhaled smoke through the exhalation filter during exhalation.   
     
     
         2 . The pipe of  claim 1 , further comprising a mouthpiece on both the inhalation path and the exhalation path. 
     
     
         3 . The pipe of  claim 2 , wherein the inhalation path includes a one-way inhalation valve between the combustion bowl and the mouthpiece. 
     
     
         4 . The pipe of  claim 1 , further comprising a lid over the combustion bowl, the lid creating a substantially airtight inhalation seal with the combustion bowl. 
     
     
         5 . The pipe of  claim 4 , wherein the lid includes a one-way inhalation valve. 
     
     
         6 . The pipe of  claim 2 , further comprising exhalation vents; and wherein the exhalation path includes a one-way exhalation valve between the mouthpiece and the exhalation vents. 
     
     
         7 . The pipe of  claim 6 , wherein the one-way exhalation valve is part of the exhalation filter. 
     
     
         8 . The pipe of  claim 1 , wherein the exhalation filter includes an exhalation filter cartridge. 
     
     
         9 . The pipe of  claim 1 , further comprising an internal lighter for providing a flame to the combustion bowl. 
     
     
         10 . The pipe of  claim 9 , further comprising a timed ignition switch for controlling the length of time that a flame is delivered to the combustion bowl. 
     
     
         11 . The pipe of  claim 1 , wherein the exhalation filter includes a housing, a HEPA filter, and a foam core. 
     
     
         12 . The pipe of  claim 11 , wherein the foam core includes a central bore extending the length of the foam core, and the foam core includes odor absorbing chemicals for removing the odor from the exhaled smoke. 
     
     
         13 . A method, comprising:
 burning a combustible substance in a combustion bowl having bowl vents, the burning combustible substance creating smoke;   channeling at least portions of the smoke from the combustion bowl through the bowl vents to a smoker;   receiving exhaled smoke from the smoker;   channeling the exhaled smoke to an exhalation filter; and   filtering the exhaled smoke by the exhalation filter.   
     
     
         14 . The method of  claim 13 , wherein the smoke from the combustion bowl is channeled to the smoker via a mouthpiece and the exhaled smoke is received through the same mouthpiece. 
     
     
         15 . The method of  claim 14 , further comprising preventing the exhaled smoke from being delivered to the combustion bowl. 
     
     
         16 . The method of  claim 14 , further comprising preventing the smoke from the combustion bowl from including air from the exhalation filter. 
     
     
         17 . The method of  claim 13 , further comprising controlling the length of time that a flame is delivered to the combustible substance in the combustion bowl. 
     
     
         18 . The method of  claim 13 , wherein the exhalation filter includes a housing, a HEPA filter, and a foam core. 
     
     
         19 . The method of  claim 18 , wherein the foam core includes a central bore extending the length of the foam core, and the foam core includes odor absorbing chemicals for removing the odor from the exhaled smoke.
