Filter component for smoking

Abstract

A filter component for tobacco smoking, comprises a filter body ( 1 ), a filter core material ( 2 ), and a filter closing layer ( 3 ). The filter body ( 1 ) is a hollow cylinder, and the filter core material ( 2 ) is built in the filter body ( 1 ). At least one end of the filter body ( 1 ) is closed by the filter closing layer ( 3 ). The filter core material ( 2 ) is a granular filter material, filament filter material, folded filter material, or similar filter material having a shape structure with a large specific surface area. The filter component for smoking can be widely used in the field of tobacco and can be built into cigarettes or arranged in related accessories. The filter component for smoking can effectively filter moisture and tar in smoke, and can also ensure good smoking feel and effect.
