Portable inhalant filter device

Abstract

A device and method of use thereof enable a portable device to be moveably disposed between a smoker and an output access point of a smoking pipe. The device temporarily forms a channel for inhalants to pass from a smoking pipe to a user's mouth. The smoking pipe may be selected from at least two different pipe structures. A cross section of the channel may be circular, orthogonal or elliptical. The device may include a particulate filter positioned between an inhalant input location and inhalant output location of the device. The filter may be insertable and removable from the tube. A source ledge may extend outward from the inhalant input location and/or a mouth end ledge may extend beyond a cross-section of the channel. A plurality of removable mouthpieces may be alternatively coupled and removed from the inhalant output location. The mouthpiece or a source piece may be elastic.

         7 . The device of  claim 1 , wherein the source piece aperture has a cross sectional area less than one half of a cross sectional area of the source end. 
     
     
         8 . The device of  claim 1 , wherein the source piece aperture has a cross sectional area less than one quarter of a cross sectional area of the source end. 
     
     
         9 . The device of  claim 1 , wherein the source piece further comprises a ledge that extends outwardly from the central axis and beyond the tubular sidewall. 
     
     
         10 . The device of  claim 1 , wherein the source piece further comprises a ledge that extends outwardly from the central axis and beyond the tubular sidewall. 
     
     
         11 . The device of  claim 10 , wherein the source piece ledge is elastic. 
     
     
         12 . The device of  claim 10 , wherein the source piece ledge comprises silicone. 
     
     
         13 . The device of  claim 10 , wherein the source piece ledge extends outwardly from the central axis and away from the tube. 
     
     
         14 . The device of  claim 10 , wherein the source piece ledge forms a surface area larger than the cross-sectional area normal to the central axis of the tube. 
     
     
         15 . The device of  claim 1 , wherein the source piece is detachably coupled with the tube. 
     
     
         16 . The device of  claim 15 , further comprising a plurality of source pieces, wherein each source piece of the plurality of source pieces is detachably attachable with the tube. 
     
     
         17 . The device of  claim 15 , wherein the source piece further comprises a ledge that extends outwardly from the central axis and beyond the tubular sidewall. 
     
     
         18 . The device of  claim 15 , wherein the source piece ledge forms a surface area larger than the cross-sectional area normal to the central axis of the tube. 
     
     
         18 . The device of  claim 1 , wherein the mouth piece comprises silicone. 
     
     
         19 . The device of  claim 1 , further comprising a plurality of mouth pieces, wherein the mouth piece and each mouth piece of the plurality of mouth pieces is detachably attachable with the tube. 
     
     
         20 . The device of  claim 1 , further comprising a filter, the filter disposed within the tube. 
     
     
         21 . The device of  claim 20 , wherein the filter comprises activated carbon. 
     
     
         22 . The device of  claim 20 , wherein the filter comprises a particulate filtering material. 
     
     
         23 . The device of  claim 20 , wherein the filter comprises a filtering paper.
