2017 Mitsubishi Eclipse Cross Cabin Filter: What it does and when to replace it

Yes, the 2017 Mitsubishi Eclipse Cross is fitted with a cabin (pollen) filter. This is documented in the Mitsubishi Motors Eclipse Cross Owner’s Manual (2017–2018 ANZ editions, Maintenance section: “Air conditioner filter”), the Eclipse Cross Workshop Manual Group 55 for HVAC, and the Mitsubishi genuine parts catalogue for GK-series Eclipse Cross models, all of which list the in-cabin air filter located behind the glovebox.

For this model, the cabin filter quietly does the hard yakka of trapping dust, pollen, soot and road grime before it enters the cabin. That means cleaner air for everyone on board and less build-up on the heater core and evaporator, which helps the air-con work efficiently and keeps fogging and musty odours at bay. A fresh filter can noticeably improve airflow through the vents and reduce blower noise because the fan isn’t straining against a clogged element.

As part of regular servicing in Australia and New Zealand, it’s smart to replace the 2017 Eclipse Cross cabin filter every 12 months or 15,000–20,000 kilometres. If the car lives near the coast, spends time on unsealed roads, or has battled smoke, dust storms or high pollen seasons, shorten the interval. Technicians will also inspect for leaves and debris in the cowl intake to prevent water leaks and blower rumbles.

Signs it’s due:

• Reduced airflow even with the fan on high
• Persistent musty odours from the vents
• Greasy film on the inside of the windscreen or quick fogging
• Whistling or extra fan noise

Replacement on the Eclipse Cross is straightforward and sits comfortably within a routine service:

1. Empty and gently drop the glovebox (release the side stops and damper cord).
2. Open the rectangular filter access cover on the HVAC unit.
3. Slide out the old filter, noting the airflow/up arrow orientation.
4. Insert the new filter with the arrows matched to the housing marking, refit the cover, and close the glovebox.

A quality charcoal/activated-carbon element is worth the small upgrade for better odour control and finer particle capture. Avoid trying to wash or blow out a used filter, the media can tear or compact and restrict flow. Keeping this simple item on schedule helps the Eclipse Cross’s HVAC run quieter, smell fresher, and last longer—exactly what Mitsubishi’s service guidance intends.

Popular questions

Where is the cabin filter on a 2017 Mitsubishi Eclipse Cross?
It’s behind the glovebox. Lower the glovebox by releasing the side stops and damper, remove the small rectangular access cover on the HVAC unit, and the filter slides straight out. This location is confirmed in the Owner’s Manual maintenance section and the HVAC Group 55 workshop procedures.

How often should the cabin filter be replaced in Australia or New Zealand?
Generally every 12 months or 15,000–20,000 km. If the vehicle sees lots of dust, bush tracks, construction zones or heavy pollen, replace it sooner. Mitsubishi’s service schedule calls for periodic inspection and replacement based on condition.

Can the original cabin filter be cleaned and reused?
Best practice is to replace it. Tapping or blowing it out can damage the fibres, reduce filtration efficiency, and still leave fine dust that restricts airflow. A fresh element is inexpensive insurance for clear screens, quiet fans and clean cabin air.
