Baldwin PA5649 Cabin Air Filter

This Baldwin PA5649 is a rectangular automotive cabin air filter designed to clean incoming airflow for the passenger compartment. It fits vehicles that specify this exact part number and dimension set. Buyers needing an engine air filter or a different cabin filter size should verify their application before ordering.

Installation and Common Issues

The element installs into the vehicle's cabin filter housing, typically accessed behind the glove box or under the dashboard. No tools are usually required beyond opening the housing door. The most common issue is ordering the wrong dimensions; this filter measures 18 1/2 in length by 4 9/16 in width by 2 1/4 in height, so confirm the housing matches exactly.

Pre-Purchase Checks

Check your vehicle service manual or the existing filter for the part number PA5649 and the listed dimensions. Ensure the housing accepts a rectangular element of this specific length, width and height. This product is not for buyers who need a different filter shape, size or part number.

Questions about this item

How can I confirm the Baldwin PA5649 cabin air filter is installed correctly?

After installation, verify the filter sits flush in the housing with the 18 1/2 in length and 4 9/16 in width aligned to the frame, then run the HVAC system to check for unrestricted airflow and no unusual noise.

What comes with the PA5649 air filter and what must I purchase separately?

The box contains the rectangular cabin air filter element only; no housing, clips, or installation hardware are included, so reuse existing fasteners or buy them separately if they are worn.

Which version of the Baldwin PA5649 should I choose for my vehicle?

The PA5649 is a single specification — 18 1/2 in long, 4 9/16 in wide, 2 1/4 in high — so select it only when your service manual lists those exact dimensions for the cabin air filter slot.
