Parts for your 2019 Mitsubishi Eclipse cross-Cabin filter

2019 Mitsubishi Eclipse Cross cabin filter: what it does and when to replace it

Yes, the 2019 Mitsubishi Eclipse Cross is fitted with a cabin air filter. Technical references that confirm this include the 2019 Eclipse Cross Owner’s Manual (Heating and Air Conditioning section, “Air conditioner filter”) and the Mitsubishi Service Manual for Eclipse Cross (Group 55A HVAC, “Air filter – removal/installation”), both of which specify a replaceable cabin filter located in the HVAC unit behind the glove box.

In this model, the cabin filter’s job is to keep the air inside the cabin clean by trapping dust, pollen, soot and road debris before it reaches the vents. It helps reduce allergens, tones down outside odours, and protects the heater core and evaporator from clogging up. A healthy filter means clearer windows, quieter fans and a fresher-smelling interior on daily commutes and long Kiwi or Aussie road trips alike.

As part of regular servicing, it’s smart to replace the Eclipse Cross cabin filter every 15,000–20,000 km or 12 months, whichever comes first. In dusty, rural or bushfire-affected conditions, shorten that interval. The Mitsubishi service schedule for local markets typically lists the air conditioner filter for periodic replacement, quick checks between services help avoid blocked airflow and overworking the blower motor.

Signs it’s time for a new filter include:

• Weaker airflow even with the fan on high
• Persistent musty or dusty smells from the vents
• Windows fogging more easily
• Extra fan noise or a whistling sound from the vents

Replacement is a straightforward glovebox-out job on the Eclipse Cross. Drop the glovebox, slide out the filter tray, and install the new element with the “AIR FLOW” arrow pointing the right way (usually down). Avoid washing the old filter, once clogged, it won’t recover. If city driving or tunnel fumes are common, consider an activated carbon (charcoal) version to better cut odours and some exhaust gases. During a service, it’s also worth clearing leaves from the cowl area so the fresh-air intake stays unobstructed, keeping the new filter cleaner for longer.

Keeping the cabin filter fresh is a quick win for comfort and HVAC longevity—and it makes every trip in a 2019 Eclipse Cross feel that bit cleaner and easier on the nose.

Where is the cabin filter in a 2019 Eclipse Cross?

It sits in the HVAC housing behind the glove box. Drop the glovebox to access the rectangular filter tray, slide the old element out, and fit the new one with the airflow arrow correctly oriented.

How often should it be replaced in Australia or New Zealand?

Plan on every 15,000–20,000 km or 12 months. If you drive on unsealed roads, in heavy traffic, or through bushfire smoke or dust, shorten the interval and check it at each service.

Is a carbon (charcoal) cabin filter worth it?

Yes if you’re often in city traffic or prone to odours, carbon media helps reduce smells and some gases. For allergy relief in spring, a high-efficiency particulate filter can be a good pick as well.
