A "Safer" Cigarette, 1950s–2010s
Throughout the 1950s, cigarette manufacturers developed proprietary filter technology that promised lower tar and nicotine content and a “safer” cigarette.

Of the early filtered brands, Kent and its “Micronite” filter were the most popular. It was later discovered that the filter contained a particularly dangerous variety of asbestos.
