Vapor Genie is the world�s first vaporizer pipe that uses a patented high purity inert silicon carbide ceramic flame filter, made of silicon and carbon. The flame filter acts as a heat transport where heat and cool air are combined to create vapors! The Vapor Genie will not be clogged with tar, because very little tar is produced by vaporization! The Vapor Genies flame filter does not burn or deteriorate, since it doesn�t contain metals, thus eliminating replacement! Nevertheless, for added filtration, Vapor Genie uses a 316 stainless steel mesh screen - the most chemically inert alloy of stainless steel. Simply, twist off the top portion of the pipe containing the flame filter to unveil the herb bowl. Loosely pack the bowl with grounded herbs, twist the flame filter back on, and apply flame while inhaling to create vapors.
