Low emissions electronic smoking device and emissions filtering device

Abstract

The present disclosure provides, in one embodiment, an electronic smoking device comprising a mouthpiece; a vaporizer portion in communication with the mouthpiece; a filter cartridge assembly in communication with the mouthpiece; an inlet check valve; and an outlet check valve. The vaporizer portion comprises a heating element for heating a smoking material housed within the vaporizer portion. The inlet check valve permits air to be inhaled from the vaporizer portion into the mouthpiece, but substantially prohibits air from being exhaled through the mouthpiece into the vaporizer portion. The outlet check valve permits air to be exhaled through the mouthpiece into the filter cartridge assembly, but substantially prohibits air from being inhaled from the filter cartridge assembly into the mouthpiece.

1 . A filter cartridge assembly for filtering emissions, the filter cartridge assembly comprising:
 a mouthpiece into which emissions can be exhaled into the filter cartridge assembly; and   a porous filter in communication with the mouthpiece such that substantially all emissions that are exhaled into the filter cartridge assembly pass through the porous filter.   
     
     
         2 . The filter cartridge assembly of  claim 1 , wherein the porous filter comprises a mesh filter. 
     
     
         3 . The filter cartridge assembly of  claim 2 , wherein the mesh filter comprises a stainless steel material. 
     
     
         4 . The filter cartridge assembly of  claim 2 , wherein the mesh filter comprises a polymer material. 
     
     
         5 . The filter cartridge assembly of  claim 2  wherein the mesh filter comprises a HEPA filter.
