Device for filtering smoke

A device for filtering smoke, with a wrap formed by a filter wrap paper, wherein at least a first section, a second section and a third section are provided in the wrap, wherein the second section is disposed between the first section and the third section, wherein

• a first nonwoven filter material is provided in the first section;
• a porous filter material is provided in the second section;
• and a second nonwoven filter material is provided in the third section;
• wherein a fourth section is provided in the wrap, wherein the third section is disposed between the second section and the fourth section, and wherein the fourth section is configured in a manner such that a pressure drop over the fourth section is smaller than a pressure drop over the third section as a flow of smoke passes through the wrap from the first section to the fourth section, wherein the fourth section has a support element that supports the wrap in the region of the fourth section;
• wherein the porous filter material is activated carbon;
• wherein the first section and the third section are disposed in a manner such that a pressure drop over the first section is greater than the pressure drop over the third section as the flow of smoke passes through the wrap, wherein the pressure drop over the first section is at least 1.5 times the pressure drop over the third section;
• and
• the first nonwoven filter material has a greater density than the second nonwoven filter material, wherein the density of the first nonwoven filter material is more than 1.4 times the density of the second nonwoven material.
