Automotive air media

Fibertex synthetic nonwovens and nanofiber treated products are available for a wide range of automotive air filtration applications, both as surface filtration and depth filtration media.

Filtration efficiencies range from Iso Coarse / MERV 10 with standard polyester nonwoven, up to E11 / MERV 17 with nanofiber treatment.


Fibertex nanofiber treatment in-depth loading filters offer exceptional filtration efficiency, with low pressure drop, without any electret charge. Pure mechanical filtration ensures no efficiency loss during the lifetime of the filter, 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.
