Fibertex synthetic nonwovens and nanofiber treated products are suitable for use in various functional layers in protective face masks and respirators. Functions include moulding supports, particulate efficiency layers and barriers against viruses and bacteria and liquid penetration. Fibertex activated carbon products are highly effective in the control and absorption of odours, smoke and liquids.

Mask materials are available up to FFP3 / N95 efficiency levels and respirators materials up to HEPA 13 efficiency level.

Filtration - Protective clothing

Fibertex nanofiber treatment in depth loading filters offer exceptional filtration efficiency, with low pressure drop, without any electrical charge. Pure mechanical filtration ensures no efficiency loss during the lifetime of the mask or respirator, which normally results from electrical discharge caused by pollution and humidity.

Fibertex depth filtration media – which extends service-life of the filter – have a gradient structure, comprising an initial pre-filter layer, a dust holding layer and the final nanofiber layer. Media are available in various thicknesses, depending on end-use requirements.
