Mann+Hummel new air filter is made from recycled fibres

Filtration major Mann+Hummel has developed a new air filter medium made from recycled synthetic fibres.

"One square metre of the filter medium contains the plastic from around two 1.5-litre PET bottles. The filter therefore makes an important contribution to the conservation of resources," says Dr Till Batt, expert in synthetic air filter elements at Mann+Hummel. "Our aim is to increase the amount of recycled fibres in new developments to 80 percent."

The new Mann-Filter C 24 005 air filter 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 millimetres. By way of comparison, a human hair measures 0.05-0.07 millimetres. 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 characterised by its flame-retardant properties.

The C 24 005 looks different to other air filters, with the green colour 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. The company says, further air filters with the innovative medium are already in preparation.
