A pair of vehicle door panels defines a cavity. An air sensor has an air inlet protruding into the cavity and senses an air pressure within the cavity. A shield covers the air inlet, has at least one side wall extending away from the air inlet, and defines a chamber configured to collapse in response to an increase in the air pressure to excite the air sensor.

Embodiments of the present disclosure help to increase the reliability of differential static pressure sensor readings used to remotely monitor the performance of an HVAC air filter. Embodiments of the present disclosure solve two problems, one related to degraded reliability of a differential pressure sensor and the second due to airflow properties such as turbulence impacting the accuracy and repeatability of differential pressure readings. Sensor reliability and lifetime are improved by reducing the access to and accumulation of dust at the sensor element by design of the air column to the sensor. The loss of accuracy and repeatability of sensor readings produced by properties of the airflow such as turbulence, among others, is reduced by a design and placement of a manifold that extends into the incoming air flow from the filter frame.
