Where the cabin filter sits and what it does

The cabin filter in your 2013 Volvo XC90 cleans the air that flows through your heating, ventilation, and air conditioning system before it reaches the interior. Over time, it traps dust, pollen, and other particles, and when it becomes clogged, your climate control works harder and the air inside feels stale. Replacing it is one of the simpler maintenance tasks you can do yourself, and it costs far less than having a dealer handle it.

In the 2013 XC90, the cabin filter is located behind the glove compartment on the passenger side of the dashboard. You do not need to remove the entire glove box — just drop the door down to access the filter housing. The whole job typically takes 10 to 15 minutes once you have the replacement filter in hand.

Key Takeaways

  • The cabin filter sits behind the glove compartment door on the passenger side and can be accessed by dropping the door down without full removal.
  • Volvo part number 31318487 is the original equipment filter for the 2013 XC90, though aftermarket filters from other manufacturers fit the same housing.
  • You will need only a replacement filter and possibly a flat tool to help release the glove box door — no special tools or disconnections required.
  • A clogged filter reduces airflow through your climate system and can make the cabin smell stale; replacing it annually or every 15,000 miles keeps air quality consistent.

Getting the right replacement filter

The original Volvo cabin filter for the 2013 XC90 is part number 31318487. If you order this part number from a Volvo dealer, a parts supplier, or an online retailer, you will receive the exact filter that came in your vehicle. The cost ranges depending on where you buy it, but aftermarket filters designed for the 2013 XC90 are also available and fit the same housing at a lower price point.

Before you buy, confirm that whatever filter you choose is listed as compatible with the 2013 Volvo XC90. Some filters are sold by engine size or trim level, so double-check the product description or ask the seller. Having the correct filter on hand before you start prevents a trip back to the store mid-job.

Steps to remove the old filter

Start by opening the glove compartment door fully. On the right side of the door (the side closest to the door hinge), you will see a small tab or clip on each side. Gently squeeze or push these tabs inward, and the door will drop down on its hinges rather than swinging open all the way. This gives you clear access to the filter housing behind it.

Look up into the space where the glove box was. You will see a rectangular plastic housing with the filter inside. The housing has a cover or frame that slides or clips in place. Slide the old filter out of the housing — it should come free with gentle pressure. If it is very dusty, you may want to wear a dust mask or have a small vacuum nearby to catch loose particles.

Installing the new filter

Before you slide the new filter in, check the direction of the airflow arrow printed on the filter frame. The arrow should point downward, toward the cabin, not upward toward the outside air. Slide the new filter into the housing with the arrow pointing in the correct direction. It should fit snugly but not require force.

Once the filter is seated, close the housing cover or frame if it has one. Then close the glove box door by pushing it back up until you hear or feel it click into place. The tabs you squeezed earlier will re-engage automatically. Open and close the door once more to confirm it is find, then you are finished.

When to replace your cabin filter

Volvo recommends replacing the cabin filter every 15,000 miles or once per year, whichever comes first. If you drive in dusty conditions, tow a trailer, or live in an area with high pollen counts, you may need to replace it more often. A good sign that it is time is when you notice reduced airflow from the vents or a musty smell when you first turn on the climate system.

Keeping track of your replacement schedule is easier if you note the date and mileage on the new filter itself with a marker before you install it. That way, the next time you open the glove box, you will see at a glance when the current filter went in.

Troubleshooting common issues

If the old filter is stuck and will not slide out easily, do not force it. Instead, gently rock it side to side while pulling, or use a flat plastic tool like a credit card to help ease it out. Forcing a stuck filter can damage the housing and create a gap where unfiltered air leaks in.

If the new filter does not seem to fit, double-check that the airflow arrow is pointing the right direction — sometimes a filter will slide in backward and feel wrong. Also confirm that you have the correct filter for your vehicle. If you are still having trouble, take a photo of the housing and the filter you purchased and show it to the parts supplier or a technician to verify compatibility.

Frequently Asked Questions

Do I have to drop the glove box door, or can I remove it completely?

You can remove it completely if you prefer, but it is not necessary. Dropping the door down gives you enough room to access the filter housing. Removing the door entirely involves disconnecting clips and takes longer, so most people find the drop-down method faster and simpler.

What happens if I drive with a clogged cabin filter?

Your heating and air conditioning will work harder to push air through the clogged filter, which reduces airflow and makes the system less effective. You may also notice odors inside the cabin. The system itself will not be damaged, but your comfort and air quality will suffer until you replace the filter.

Can I clean the old filter instead of replacing it?

Cabin filters are designed to be replaced, not cleaned and reused. Vacuuming or tapping out loose dust might temporarily improve airflow, but the filter will not trap particles as effectively as a new one. Replacement is inexpensive enough that cleaning is not worth the effort.

Is there a cabin filter on the driver's side too?

No, the 2013 XC90 has one cabin filter located behind the passenger-side glove box. This single filter handles air for the entire cabin, regardless of which vents you have open or which climate zones you are using.
