Mazda CX-30 Cabin Air Filter: Part Number & Replacement Guide

The cabin air filter in your Mazda CX-30 is a small, inexpensive part that has an outsized effect on the air you breathe inside the car. It traps pollen, dust, and road grime before they reach the vents, and a clogged one is a common cause of weak airflow and musty odors. This guide covers the correct part number for the CX-30, how often to replace it, and how to do it yourself in a few minutes.

Which cabin air filter fits a Mazda CX-30?

The Mazda CX-30 (2020-present) uses a single cabin air filter design across all model years. The correct genuine OEM part is:

  • 2020-present Mazda CX-30: Part # BDGF-61-J6X (Genuine OEM, fits Mazda3 / CX-30 / CX-50, Japan built)

Entering your VIN at checkout is the fastest way to confirm you are ordering the correct filter for your exact build.

How often should you replace the CX-30 cabin air filter?

Mazda generally recommends replacing the cabin air filter approximately every 12,000 to 15,000 miles, or once a year. If you drive frequently in dusty conditions, heavy traffic, or areas with high pollen, replacing it more often keeps airflow strong and odors away.

Signs your cabin air filter needs replacing

The most common symptoms are reduced airflow from the vents even at high fan speed, a musty or dusty smell when the climate system runs, increased window fogging, and a whistling sound from the HVAC intake.

Is replacing the CX-30 cabin air filter a DIY job?

Yes. On most Mazda models the cabin filter sits behind the glovebox and can be reached in a few minutes with no tools: open the glovebox, release the side stops so it drops fully, remove the filter cover, slide out the old filter, and insert the new one following the airflow arrow on its frame. The job typically takes 5 to 10 minutes.

Frequently asked questions

Which way does the cabin air filter go in? Follow the airflow arrow on the edge of the filter frame - it should point in the direction of airflow, generally downward toward the blower on most Mazda installations.

Can a dirty cabin filter affect my air conditioning? Yes. A clogged filter restricts airflow across the evaporator, which reduces how much cool air reaches the cabin and makes the blower work harder.

Does the CX-30 have more than one cabin filter? No - like most compact crossovers, the CX-30 uses a single cabin air filter located behind the glovebox.
