Material: Nonwoven fabric (Vliesstoff) + Activated carbon (Aktivkohle) Key benefits Dual-action filtration: the nonwoven layer provides mechanical capture of dust and particles; activated carbon adsorbs odors and many volatile compounds. Improved comfort and airflow: lightweight, breathable construction helps maintain airflow while adding filtration. Versatile and unobtrusive: thin, flexible materials integrate into filter assemblies or mask pockets without adding bulk. What this material does Particle control: traps dust, pollen and other airborne particulates through the nonwoven fabric. Odor and gas adsorption: activated carbon reduces odors, smoke and many common airborne contaminants by adsorption to its high-surface-area structure. Layered performance: combining both materials balances mechanical filtration with chemical adsorption for broader air quality improvement. Important attributes Material: Vliesstoff (nonwoven fabric) + Aktivkohle (activated carbon) — no additional components are claimed. Function: mechanical particle filtering plus adsorption of odors and volatile compounds. Form factor: flexible, lightweight layers suitable for incorporation where a nonwoven + activated carbon layer is required. Typical applications Mask inserts: useful as an additional layer to help reduce odors and particulate load in personal face coverings. Portable air cleaners and filter cartridges: functions as a filter layer or supplement in compact purification units or hobby filter builds. Small-space odor control: appropriate for inserts or liners in pet areas, closets or kitchen vents to help reduce smells. Handling and performance notes Avoid prolonged exposure to moisture, which can reduce adsorption capacity. Replace the material when odor control or filtration performance noticeably declines, as activated carbon becomes saturated over time.
