The Smoking Slim Active filters of the Spanish manufacturer contain activated carbon from coconut shells.

These filter out various toxic and harmful particles through their surface structure and thus give the cigarette a milder taste. The ceramic caps indicate how to properly insert the activated carbon filter. The filters can be used several times and thus pollute the environment less. Speaking of the environment, the Smoking Active filters belong to the Brown series of the traditional brand, which means they are biodegradable. With a length of 27 mm, they can also be perfectly twisted into king size papers, while their diameter of 6 mm also perfectly fits thin cigarettes.
