Maintain ACX7020 Air Filter

Learn how to install and replace the air filter.

The ACX7020 router has an air filter installed on the side of the chassis. To ensure optimum cooling, you must regularly inspect the air filter. A dirty air filter restricts the airflow in the unit, producing a negative effect on the ventilation of the device. The filter degrades over time and you should replace it every 6 months.
