Beginning June 2016, compact Audi models will roll off the assembly line with a new filter in the air- conditioning system. The new air filter not only removes fine particulates and harmful gases from the air, it also neutralises a majority of all allergens.

The new air-conditioning filter will be used in the Audi A1, A3, Q3 and TT model series beginning in June. The new Q2 will be equipped with the filter at market launch. Customers can also have their cars in the respective model series retrofitted with the new filter as part of their regularly scheduled service intervals.

The filter is available in two versions, each of which comprises three layers. They work differently, however. Their new outer carrier layer features an additional anti-allergen effect. One variant reduces allergens by means of plant-derived, bio-active substances called polyphenols, which attach themselves to the receptors of the allergens. The other uses a modification of the protein structure to achieve the desired effect. Independent tests by specialised testing institutions such as SGS Fresenius, which investigates the allergenic properties, and Fiatec GmbH, which tests the filter properties, confirm the effectiveness of the new Audi filters.

Further, the two layers present in existing filters also make a significant contribution to the high air quality in the interior. The filtration layer made up of special microfibers removes even the tiniest of particulates from the air. Gaseous impurities are trapped in the activated carbon layer.

Moreover, the arrangement of the layers also ensures outstanding separation performance and conditioner air throughput over the life of the filter.
