Abstract
A method of manufacturing a filter that includes providing a tube having a cylindrical wall and a hollow interior. The method forms a first indentation within the tube in which a first portion of the of the cylindrical wall concaves into the hollow interior, and forms a second indentation within the tube in which a second portion of the cylindrical wall concaves into the hollow interior. The first and second indentations create 1) a first chamber and a second chamber in the tube that are separated by both indentations and 2) a path within the hollow interior formed between the first and second indentations that fluidly couples both chambers together.

A method of manufacturing a filter comprising:
- providing a tube having a cylindrical wall and a hollow interior;
- forming a first indentation within the tube in which a first portion of the cylindrical wall concaves into the hollow interior;
- and
- forming a second indentation within the tube in which a second portion of the cylindrical wall concaves into the hollow interior,
- wherein the first and second indentations create 1) a first chamber and a second chamber in the tube that are separated by both indentations and 2) a path within the hollow interior formed between the first and second indentations that fluidly couples both chambers together.
A tube filter for smoking a smokable substance, the tube filter comprising:
- a receiving section having a receiving chamber dimensioned to receive the smokable substance;
- a smoke section having a smoke chamber to output smoke produced while the smokable substance is ignited, wherein the smoke section has a first open end into the smoke chamber and the receiving section has a second open end into the receiving chamber that is opposite to the first end;
- and
- a first indentation and a second indentation that separates the receiving chamber from the smoke chamber, the first indentation formed from a first concave portion of a wall of the tube filter and the second indentation formed from a second concave portion of the wall of the tube filter, wherein the first concave portion and the second concave portion are only partially radially aligned about a center longitudinal axis of the tube filter with one another, wherein the first indentation and the second indentation form a path inside the tube filter that fluidly couples the receiving chamber to the smoke chamber and that runs diagonally through the center longitudinal axis of the tube filter.
