1. A filter for smoking, comprising:
a filter medium formed of heat resistant fibers that is a high efficiency filter capable of removing substantially 100% of particles and capable of delivering vapor components substantially completely; and
a heater heating the filter medium and a periphery of the filter medium, the heater completely surrounding the periphery of the filter medium and being capable of controlling the temperature within a range of between 125° C. and 150° C.,
wherein the filter medium selectively removes high boiling point components in a smoke.
2. The filter for smoking according to claim 1 , which further comprises a cooling section.
3. The filter for smoking according to claim 1 , which further comprises a charcoal filter.
4. The filter for smoking according to claim 1 , which comprises a first upstream filter medium set at a first temperature and a second downstream filter medium set at a second temperature lower than said first temperature, which selectively condenses a part of high boiling point components in a smoke.
5. The filter for smoking according to claim 1 , wherein the high boiling point components include benzo[a]pyrene and aromatic amines.
