Filter for Smoking Article

Abstract

A filter for a vapour generating article includes a filter body having: a first end arranged as a mouthpiece; a second end opposite the first end arranged for attachment to a vapour generating article; the filter further including a cavity located within the filter body between the first and second ends, the cavity configured to allow a fluid including water to flow through the filter body from the second end to the first end; wherein the cavity includes a filter portion arranged to filter the fluid as it flows through the filter body; and wherein the filter portion is arranged to remove at least some of the water from the fluid as it flows through the filter body.

1 . A filter for a vapour generating article comprising:
 a filter body comprising:
 a first end arranged as a mouthpiece; and 
 a second end opposite the first end arranged for attachment to a vapour generating article; and 
   a cavity located within the filter body between the first and second ends, the cavity configured to allow a fluid comprising water to flow through the filter body from the second end to the first end;   wherein the cavity comprises a filter portion arranged to filter the fluid as the fluid flows through the filter body; and   wherein the filter portion is arranged to remove at least some of the water from the fluid as the fluid flows through the filter body.   
     
     
         2 . The filter of  claim 1 , wherein the filter portion comprises a selective filter medium arranged to selectively filter water from the fluid. 
     
     
         3 . The filter of  claim 2 , wherein the selective filter medium comprises a water-absorbing medium. 
     
     
         4 . The filter of  claim 3 , wherein the water-absorbing medium comprises silica. 
     
     
         5 . The filter of  claim 3 , wherein the water-absorbing medium comprises a molecular sieve. 
     
     
         6 . The filter of  claim 3 , wherein the water-absorbing medium comprises a hydrophilic sponge material. 
     
     
         7 . The filter according to  claim 1 , wherein the second end of the filter is releasably attachable to a vapour generating article. 
     
     
         8 . A vapour generating article comprising:
 a first end arranged for connection with a vapour generating device;   a filter according to  claim 1 , wherein the filter is attached to a second end of the vapour generating article.   
     
     
         9 . A vapour generating system comprising:
 a filter according to  claim 1 ;   a vapour generating article comprising a first end arranged for connection with a vapour generating device, wherein the filter is attached to a second end of the vapour generating article; and   a vapour generating device configured to receive the vapour generating article.
