The fibres are extremely pure due to a complex extraction process during production. The fineness of the individual product types is determined by special grinding and fibrillation of the various fibres.

CelluFluxx^® F15 has extra short fibres for sharp filtration and germ-reducing filtration. These fibres are used instead of or in combination with the product type CelluFluxx^® F25 to specifically increase the clarity.
