actiTube Slim 7mm

7 mm is considered by many to be the ideal diameter. With it we developed the world’s first real activated charcoal joint filter and later set standards for some imitators. Like its older brother, the 7 mm SLIM filter is well-filled and filters almost as well as its larger model. Nevertheless, it has a very handy size and therefore enjoys the greatest popularity among our filters. Like all actiTube products it is made in Germany.
