Audi's small cars will soon all have a new style air filter to boost the filtration of a vast amount of substances.

New filter system for compact Audi models will help to bring relief to allergy sufferers

• Active substances in filter reduce allergens
• Additional layers against fine particulates and gaseous impurities
• Use in Audi A1, A3, Q3 and TT from June; in Audi Q2 at launch

From June 2016, compact Audi models will bring a breath of fresher air to their occupants thanks to a new air conditioning filter that not only removes fine particulates and harmful gases from the air, but also neutralises virtually all allergens. 

With the new filter, which will be used in the Audi A1, A3, Q3 and TT model series from June, Audi is setting a new standard worldwide in the premium compact segment.

The new Audi Q2 compact SUV 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.

Two versions of the filter will be used, each of which comprises three layers. What makes them special is the new outer carrier layer, which now features an additional anti-allergen effect. One variant reduces allergens by means of plant-derived, bioactive 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 specialist testing institutions such as SGS Fresenius, which investigates the allergenic properties, and Fiatec GmbH, which tests the filter properties, confirm the high effectiveness of the new Audi filters.

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

A comprehensive measurement series documents the high effectiveness of the filter system. The arrangement of the layers ensures outstanding separation performance and conditioner air throughput over the life of the filter.
