Baldwin Filters PA3900 cabin air filter

The Baldwin Filters PA3900 is a rectangular automotive cabin air filter measuring 12 1/2 in length, 6 1/2 in width and 1 3/4 in height. It is designed for vehicle owners and technicians replacing the cabin air element during routine maintenance.

Sustained filtration performance

Under continuous airflow the filter media traps dust, pollen and road debris without collapsing or bypassing. The rectangular element maintains its seal throughout the service interval so airflow to the HVAC system remains steady.

Thermals, noise and power draw

As a passive component the filter adds no electrical load and generates no noise. It simply sits in the housing and lets air pass while capturing contaminants, leaving cabin temperature and fan sound unchanged.
