Built to original equipment form, fit and function, the Wesfil Cabin Pollen Filter covers Mazda3 models built from 2019 to 2021. The Activated Carbon media captures pollen, road dust and brake particulate down to 15 micron. Replacing this filter every 20,000km restores air conditioning airflow and reduces musty smells at start-up. Element size is approximately 250mm x 120mm and slides into the factory housing behind the glovebox. The frame is treated to resist mould and bacterial growth in humid conditions. An activated carbon layer reduces exhaust odour and diesel fumes in traffic. New stock, 24 Months warranty, and dispatched from our Australian warehouse.
