Personal smoke filter or smoke trap

Abstract

A personal smoke filter or smoke trap includes a hollow tube having an input opening to receive the smoke exhaled by a user, and an exit opening. The tube contains a paper filter; a first fiber filter; a carbon filter; and a second fiber filter. The fiber may be polyester. The smoke passes through the filters and out the exit opening, thereby filtering the smoke. Also included are end caps to seal the tube.

1 . A device to filter smoke, comprising:
 a hollow tube having an input opening adapted to receive the smoke, and an exit opening;   a paper filter within the tube;   a first fiber filter within the tube;   a carbon filter within the tube; and   a second fiber filter within the tube;   wherein the smokes passes through the paper filter, through the first fiber filter, through the carbon filter, through the second fiber filter, and out the exit opening, thereby filtering the smoke.   
     
     
         2 . The device of  claim 1 , wherein the first fiber filter includes polyester and the second fiber filter includes polyester. 
     
     
         3 . The device of  claim 1 , wherein the input opening is adapted to receive the smoke from a mouth of a user who blows the smoke into the device. 
     
     
         4 . The device of  claim 1 , further comprising:
 a first end cap to releasably seal the input opening; and   a second end cap to releasably seal the output opening.   
     
     
         5 . The device of  claim 1 , further comprising:
 an air space inside the tube between the input opening and the paper filter.   
     
     
         6 . The device of  claim 5 , wherein the air space is approximately 1.5 inches long. 
     
     
         7 . The device of  claim 1 , further comprising:
 an exhaust exit opening ring.   
     
     
         8 . A personal smoke filter, comprising:
 a paper filter;   a first polyester filter;   a carbon filter;   a second polyester filter;   a hollow tube having an input opening adapted to receive the smoke from a mouth of a person, and an exit opening, the tube containing the paper filter, the first polyester filter; the carbon filter, and the second polyester filter; and   an exhaust exit opening ring for the exit opening of the hollow tube.   
     
     
         9 . The filter of  claim 8 , further comprising:
 a first end cap for the input opening; and   a second end cap for the output opening.   
     
     
         10 . A method for filtering smoke, comprising:
 receiving the smoke from a mouth of a user who exhales the smoke;   passing the smoke through a hollow tube;   forcing the smoke in the tube through a paper filter, a first fiber filter, a carbon filter, and a second fiber filter; and   expelling the filtered smoke.
