Activated Carbon for Cigarette Filter

Activated carbon is a common and effective application for cigarette filters. Its main purpose is to improve the filtering effect and reduce the inhalation of harmful substances. 

The role of activated carbon in cigarette filters:

1. Adsorption of harmful gases: Activated carbon has a developed pore structure and ultra-high specific surface area, which can effectively adsorb toxic and harmful gases such as carbon monoxide, hydrocyanic acid, benzene, formaldehyde, etc. in smoke.

2. Improve taste: By reducing irritating components, activated carbon helps smokers feel that the smoke is smoother and softer.

3. Extend filter life: Compared with traditional filters, activated carbon can extend the filtration time and improve filtration efficiency.

4. Customizable performance: Activated carbon with different particle sizes, pore structures and surface characteristics can be customized according to the needs of different brands and markets.

Usage form:

- Granular activated carbon: Most commonly used in cigarette filters, installed in the cavity in the middle of the filter.
- Rod or spherical carbon: used in high-end cigarette products to improve adsorption performance and appearance design.
- Composite materials: activated carbon is compounded with other materials (such as cellulose acetate) to improve versatility.

Development trends:

As consumers' health awareness increases and regulations become stricter, more and more cigarette brands use activated carbon filters to reduce risks. Some countries also have clear standards for the type and amount of activated carbon added to cigarette filters.
