Audi‘s compacts get improved air filtration to scrub allergens

Audi has announced plans to introduce improved cabin air filters across its entire compact lineup.

The filters feature three layers to remove harmful particles and gases from the air and neutralize allergens. Two variants are available, each distinguished by a unique active outer layer to deal with allergens.

One type integrates a plant-derived bioactive substances known as polyphenols, which are said to bind to receptors on allergens. The second design employs “a modification of the protein structure” to achieve similar effects.

“Independent tests by specialized 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 company said in a statement.

The other two layers, currently found in existing filters, include a microfiber particle filter and an activated carbon layer. The former removes particulates, while the latter entraps gasses.

Beginning in June, the enhanced filters will become standard on the A1, A3, Q3 and TT, while the Q2 will be equipped at launch later in the year. The filters are backwards-compatible with existing vehicles, available from dealers or installed during regular scheduled service.
