"This cigarette filters out harmful ingredients in advance..."
The filter component that filtered it was asbestos...ㄷㄷㄷㄷㄷ

In the early days of production, it used a specially made filter called Micronite and advertised that it could remove harmful substances from cigarettes, attracting many users. At a time when the harmfulness of cigarettes was gradually being revealed through research and the smoking cessation rate was steadily increasing in the United States, Kent's marketing worked, and many smokers switched to Kent, and even those who had quit smoking started smoking Kent again. However, the main ingredient of that special filter called Micronite turned out to be asbestos, and eventually Kent quietly replaced the main ingredient of the filter with fiber four years later.
Asbestos has a high risk of carcinogenicity, but it has a very long latency period. As a result, smokers who smoked Kent's asbestos filter cigarettes began to develop cancer after more than 10 years and started living with illness or dying. (There are even reports of cases where it occurred in people who had quit smoking for over 20 years.) Due to this, they faced several civil lawsuits from smokers and their families, and it is said that they continue to this day as we enter the 2020s. Anyway, since 1956, asbestos filter cigarettes have been completely discontinued, and like other cigarette brands, fiber filters are used.
