From June 2016, newly built compact Audi models will feature a new filter in the air conditioning system. This filter removes not only fine particulates and harmful gases from the air, but also neutralises the majority of all allergens. With this new filter, Audi is setting a new standard worldwide in the premium compact segment.
This new air conditioning filter will feature in the Audi A1, A3, Q and TT model series from June while the new Audi Q2 will be equipped with the filter at market launch. Customers can also choose to have their cars in the respective model series retrofitted with the new filter as part of their regularly scheduled service intervals.
The filter will come in two different versions, each of which is made up of three layers. What makes them special is the new outer layer carrier, which now boasts and additional anti-allergen effect.
One variant uses plant-derived, bioactive substances called polyphenols which reduce allergens by attaching themselves to the allergen's receptors. The other uses a modification of the protein structure to achieve the desired effect. Independent tests by specialised testing institutions which investigate allergenic properties or tests filter properties, such as SGS Fresenius and Fiatec GmbH, confirm the effectiveness of the new Audi filters.
The two layers that exist in the current filters also make a significant contribution to the high air quality in a vehicles interior. The filtration layer, which is made of special microfibres, removes even the smallest of particulates from the air while gaseous impurities are trapped in the activated carbon layer.
A comprehensive measurement series records the high effectiveness of the filter system while the arrangement of the layers ensures outstanding separation performance and conditioner air throughput over the lift of the filter.
