Accuracy note: confirmed for current generation — this same part is shared with the E-Class of the same generation, since both share the same platform-era HVAC housing.

Cabin air filter (combifilter, with built-in activated carbon layer)	Mercedes-Benz OEM: A2058350147 (also cross-referenced as A2058350047) — shared with same-generation E-Class; current Mercedes filters commonly combine standard particulate filtration and activated carbon into one part
Older Mercedes generations (pre-2010s, historical note)	A genuinely separate second activated-charcoal filter was fitted only on cars with dual-zone or higher climate control options, in addition to the primary dust filter fitted to every car — current combifilter designs have superseded this two-filter approach

Mercedes-Benz GLC Cabin Air Filter: Easy to Forget, Easy to Fix

Of everything covered for the Mercedes-Benz GLC, this is about as low-stakes mechanically as it gets — it doesn't touch how the car drives at all. Its only job is cabin air quality, which is exactly why owners tend to ignore it until something makes that hard to do.

Before you buy: filter size and whether your car uses a standard or activated-carbon filter varies by trim. Always confirm against your VIN before ordering.

Mercedes-Benz GLC Cabin Air Filter: What It Does

On the Mercedes-Benz GLC, this filter sits in the ventilation intake, not the engine bay, and cleans the air reaching the cabin — trapping dust, pollen, and on carbon-activated versions, some odours and pollutants too. The engine air filter is a completely different part, serving combustion rather than the cabin.

A Genuinely Useful, Specific Finding Worth Knowing — Mercedes-Benz GLC Cabin Air Filter

If you're trying to locate this filter, this is genuinely worth knowing directly for this model: it's positioned behind the front passenger footwell panel rather than behind the glovebox itself, accessed by opening the front passenger door and carefully removing the lower footwell trim panel, usually secured with a screw beneath it. Worth knowing this specific location before assuming the filter isn't fitted simply because it isn't where you initially expect to find it.

A genuinely honest, real account worth knowing if a smell persists after replacing this filter: a documented case saw a car with the cabin filter changed less than 4,000 miles prior, confirmed clean, still suffering from a persistent musty smell. If a smell is noticeable even without the blower running, this points strongly toward the evaporator or a blocked drain tube as the actual cause.

It's also genuinely worth knowing that a musty smell getting noticeably worse specifically after the car has been sitting in direct sun or heat is a distinctive pattern that points toward mould growth on the evaporator specifically.
