Mann-Filter presents innovative filter medium


The new Mann-Filter C 24 005 air filter offers a new filter medium made from recycled synthetic fibers.

“One square meter of the filter medium contains the plastic from around two 1.5 liter PET bottles. The filter therefore makes an important contribution to the conservation of resources,” explains Dr. Till Batt, expert in synthetic air filter elements at MANN+HUMMEL. “Our aim is to increase the amount of recycled fibers in new developments to 80 percent.”

The air filter achieves excellent filtration thanks to the multi-layer MICROGRADE A-S medium and removes at least 99.5 percent of dirt particles in the range from 0.001 – 0.352 millimeters. By way of comparison, a human hair measures 0.05 – 0.07 millimeters. Thanks to its high dirt holding capacity throughout the entire service interval, the air filter requires only 30 percent of the filter medium area of traditional air filters based on cellulose media. The C 24 005 meets the replacement intervals prescribed by the vehicle manufacturer even under dusty conditions, and is characterized by its flame-retardant properties. The C 24 005 looks different to other air filters, with the green color of its recycled fibers giving it a distinctive appearance. The new Mann-Filter C 24 005 air filter will be available in original equipment quality on the European market from November 2017 for various Toyota models. Further air filters with the innovative medium are already in preparation.

Filtration expert MANN+HUMMEL has been championing sustainable forestry for a number of years with environmentally friendly filter media for air filters. As well as meeting technical specifications, it is a priority for the company to conduct its business in a sustainable and environmentally friendly manner. The conservation of resources is an important factor in this context. MANN+HUMMEL has therefore had two production locations certified in accordance with the guidelines of the Forest Stewardship Council® (FSC) in order to be able to manufacture products with wood content from certified sources.

MANN+HUMMEL enhances its filter media on an ongoing basis in cooperation with the various filter media manufacturers in order to remain at the cutting edge of technology.
