Pure physical filtration

Pure physical filtration

Dual Filtration System

The dual physical filtration structure intercepts and adsorbs certain harmful substances such as tar and nicotine present in the smoke, separating and filtering them without involving any chemical changes. The pure physical filter will not alter the taste and flavor of the cigarette. It merely filters out some harmful substances in a physical manner, allowing smokers to enjoy the original flavor of the cigarette while reducing damage to their health. At the same time, by reducing the emission of harmful substances, it not only benefits the health of the smokers themselves but also decreases the harm of secondhand smoke to those nearby, having certain environmental protection significance.
