Parts for your 2017 Mitsubishi Asx-Cabin filter

2017 Mitsubishi ASX cabin filter — purpose, care and when to swap it

Technical sources confirm the 2017 Mitsubishi ASX is fitted with a cabin air filter (also called the A/C or pollen filter). The Mitsubishi Motors ASX/RVR service manual (HVAC/Group 55) includes a procedure to replace the A/C filter behind the glovebox, the Mitsubishi ASA electronic parts catalogue lists an “air refiner” filter for GA-series ASX models around 2017, and major fitment catalogues (e.g., Ryco Filters and Mann-Filter) specify replacement cabin filters for the 2017 ASX. So a cabin filter is absolutely relevant and used on this vehicle.

On the 2017 ASX, the cabin filter’s job is to scrub the air coming through the heater/air-con before it reaches the vents. It catches dust, pollen, soot and road grime, and a carbon-impregnated version also helps knock down odours. That means clearer windows, nicer-smelling air, and a friendlier time for anyone with hay fever or asthma.

Because Aussie and Kiwi conditions can be dusty and full of plant matter, this little filter works hard. When it clogs up, airflow drops, the fan gets noisy, demisting slows down, and the evaporator can stay damp and musty. Keeping it fresh is cheap insurance for comfort and for the blower motor.

• Check it at every service, and plan to replace it about every 15,000–20,000 km or 12 months. If you do a lot of gravel roads, city stop‑start, or park under trees, shorten that interval.
• Signs it needs attention: weak airflow even on high, musty or vinegary odours, the fan sounding like it’s working overtime, or a light film building on the inside of the windscreen.

The ASX’s filter sits behind the glovebox. Drop the glovebox, slide out the filter tray, note the airflow arrow, and swap the element. Don’t wash a paper filter—once it’s clogged or smelly, replace it. A quick vacuum or tap-out can buy a little time between services, but it won’t restore full performance. If odours bug you, consider a carbon (activated charcoal) type instead of a basic paper media.

Two handy tips: jot the kilometres and date on the filter frame when it goes in, and make sure the tray seats properly so the recirc door isn’t fouled. Keeping this small part on schedule helps the ASX’s HVAC breathe easier, keeps screens clear on damp mornings, and makes every commute feel fresher.

FAQs

Does the 2017 Mitsubishi ASX have a cabin filter, and where is it?
Yes. It uses an air‑conditioning (pollen) filter located behind the glovebox. Lower the glovebox, release the stops, slide out the rectangular filter tray, and the element is right there for inspection or replacement.

How often should the ASX cabin filter be replaced in Australia or New Zealand?
Check it each service and replace about every 15,000–20,000 km or 12 months. If you drive in dusty regions, heavy traffic, or under flowering trees, expect to replace it sooner to keep airflow and demisting up to scratch.

Can the cabin filter be cleaned instead of replaced?
A gentle vacuum or tap can remove loose debris, but paper media can’t be washed and won’t fully recover once loaded or smelly. If airflow is down or odours persist, replacement is the proper fix. Carbon filters should also be replaced, not washed.
