- The four main types of filter tips are: cardboard (rolled) tips, cotton filter tips, cellulose acetate filter tips, and activated charcoal filter tips.
- Cardboard tips provide structure and keep loose material out of the mouth. They do not contain filtering media.
- Cotton and cellulose acetate tips contain filtering material that blocks particles from passing through.
- Activated charcoal tips contain carbon granules that adsorb certain compounds from the air stream.
- Each type works differently and serves a different function.
