Baldwin PA3440 Cabin Air Filter

The Baldwin PA3440 is a rectangular automotive cabin air filter designed to clean incoming air for vehicle HVAC systems. It fits applications requiring these exact dimensions for proper sealing and airflow.

Critical fit dimensions 21 1/4 by 5 29/32 by 2

The single specification that decides fit is the overall size of 21 1/4 in length, 5 29/32 in width and 2 11/16 in height. Verify these three measurements against your vehicle manual before ordering.

Simple element swap with common sealing errors

Installation typically involves opening the glove-box or cowl access panel and sliding the old element out. The most frequent mistake is inserting the filter upside down or leaving the housing clips unlatched, which lets unfiltered air bypass the media.

Questions about this item

How does the 21 1/4 in length affect fitment in my vehicle?

The 21 1/4 in length must match the housing slot exactly; measure the old filter or check the service manual before ordering.

What does the rectangular cabin air filter design mean for airflow?

The rectangular panel sits flat in the HVAC housing and seals on all four edges to direct all intake air through the media.

Will the 5 29/32 in width and 2 11/16 in height fit my existing clips?

Those dimensions set the outer frame size; compare them to the old filter's frame to confirm the retaining clips will engage.
