The company will use two different versions of the filter, both of which feature three layers. The outer layer of the first variant uses plant-derived polyphenols that attach themselves to receptors of allergens. The other version of the filter employs modified proteins to achieve a similar effect.
The remaining two layers are common to both versions of the new filter. The second layer contains microfibres that trap and remove tiny particulates from the air, while the third layer is made up of activated carbon that catches gaseous impurities.

In the UK, the new filtration system will offered from June on the Audi A1, A3, Q3 and TT models, and the system will also be fitted to the Audi Q2 when it launches there. Owners of existing Audis can have the new filtration system retrofitted during regular servicing.
We're still waiting to hear back from Audi Australia as to when the new air filtering system will be available down under.
