Recommended Cabin Filters for Vauxhall Grandland

Twin filter — buy the pair. Vauxhall Grandland owners are routinely sold a single element because most listings, and most guides, assume one filter per car. The dimensions in the table are per filter. Check that whatever you order states a quantity of two, or buy two singles.
Coverage and variants: Twin filter — set of 2, below the glovebox. The 2022-24 facelift is still chassis A18 (Grandland X, 2017-2025). The all-new 2025 Grandland is a different car on CU 26 025-2 from 04/25 — do not carry 29 003-2 forward past the A18.
Where it sits: behind the glovebox.
Confidence in this data: High
Checked against: MANN-FILTER’s own catalogue pages and the TecDoc-derived application data. A reference that returns a 404 on MANN’s catalogue does not exist, and we do not publish it.
We deliberately do not print an OE part number here. MANN publishes OE cross-references at part level, not per vehicle, so a filter shared by six cars carries all six manufacturers’ numbers — quoting one of them as “the OE number for this car” would be guesswork. Check yours in the handbook or a dealer parts catalogue.
Particle or Activated Carbon?
MANN-FILTER uses a prefix to tell you what a cabin filter actually does. CU is a plain particle filter: it catches dust, pollen and soot. CUK adds an activated-carbon layer, which also absorbs odours and a proportion of gaseous pollutants such as nitrogen dioxide and ozone. FP (FreciousPlus) adds a biofunctional layer aimed at mould, bacteria and allergens on top of the carbon.
For the Vauxhall Grandland, MANN publishes both: the particle CU version and the activated-carbon CUK version, plus the FreciousPlus FP version. They are the same size and fit the same housing, so the choice is about what you want filtered rather than about fitment. Carbon filters cost a little more and are the better choice in heavy traffic.

How to Change the Cabin Filter
On most cars this is a ten-minute job needing no tools, or a screwdriver at most.
- Find the housing. On the Vauxhall Grandland the filter sits behind the glovebox. Empty the glovebox first if that is where you are working.
- Release the housing. Most are held by clips or a couple of screws; the glovebox itself often has to be dropped by squeezing its side stops inward.
- Note the airflow arrow printed on the edge of the old filter before you pull it out, and photograph how it sits. Fitting a filter the wrong way round halves its useful life.
- Fit the new elements — both of them with the arrow pointing the same way, then refit the cover and check it clicks home.
- Run the blower on full for a minute with recirculation off to clear anything disturbed during the change.
Remember: this car takes two elements. Changing one and leaving the other in place is a common and pointless half-job.
When to Change It
There is no single correct interval and we will not invent one. Manufacturers publish their own figure in the service schedule, and that schedule — not a generic number — is what your car is designed around. Check the handbook or service book for the figure that applies to yours.
Change it sooner than the schedule if you notice any of these:
- Weak airflow from the vents even at full fan speed
- A musty or stale smell when the blower first comes on
- The windscreen taking longer than it used to to demist
- Visible leaf litter or grit when you drop the housing
- Hay fever symptoms in the car that were not there last year
Short urban journeys, dusty roads and parking under trees all shorten a filter’s useful life well below the book figure.
Frequently Asked Questions
What cabin filter does a Vauxhall Grandland use?
The Vauxhall Grandland takes MANN-filter CU 29 003-2 / CUK 29 003-2 / FP 29 003-2. Dimensions are 293 x 96 x 32 mm per filter. Note that this car takes two elements, not one.
How many cabin filters does a Vauxhall Grandland need?
Two. The Vauxhall Grandland uses a twin filter, supplied and fitted as a pair, and the dimensions quoted are per element. Buying a single filter is the most common mistake on this car.
Can I get an activated-carbon cabin filter for a Vauxhall Grandland?
Yes. MANN publishes both a particle (CU) and an activated-carbon (CUK) version at the same reference number and the same dimensions, so both fit the same housing.
How often should I change the cabin filter on a Vauxhall Grandland?
Follow the service schedule in your handbook. We do not publish a generic mileage or time figure here because manufacturers set their own, and an invented number is worse than none. Change it sooner if airflow drops, the vents smell musty, or the screen is slow to demist.
Can I change the cabin filter on a Vauxhall Grandland myself?
Usually yes. The filter sits behind the glovebox, and on most cars it is a ten-minute job with no tools or a screwdriver at most. Note the airflow arrow on the old element before you remove it. Remember this car has two elements — change both.
How we check fitment for this guide
We cross-reference fitment figures against manufacturer specifications and OE-supplier catalogue data where available, and matched to the standard codes that actually govern fit — battery type/group sizes, wiper lengths and fitting types, bulb fitment codes, tyre size markings, and oil specifications. We work by make, model, year, engine, and build date, because a single model can take different parts across its life. Where the right part depends on your exact vehicle, we tell you to confirm by registration or VIN. More on our method →
