OEM Part Number: K2C79-AC001

Cabin air filter	Kia OEM: K2C79-AC001 (also referenced as K2C79-AC000, and shared reference 97133-D3200)
Activated carbon/charcoal variant	Hyundai/Kia genuinely distinguish standard and carbon versions with different final-digit suffixes on the same base part number (e.g. "-1000" for standard vs "-1100" for carbon on some platforms) — check the exact suffix on your existing filter rather than assuming from the base number alone

A Genuinely Useful, Real Finding Worth Knowing If a Smell Persists — Kia Sportage Cabin Air Filter

This is genuinely worth knowing if a smell survives multiple filter changes: one documented case on a related model saw a persistent smell linger even after the cabin filter had been replaced several times, with the actual cause eventually understood to be residue lingering in the intake ducting itself, upstream of the filter. If you've already changed the filter more than once without success, it's genuinely worth having the intake ducting itself cleaned or disinfected.

A genuinely useful distinguishing clue worth knowing: a specifically musty smell can indicate blocked drains in the front scuttle area beneath the windscreen wipers, causing water to collect and run internally — worth checking whether the footwell carpets feel damp, since this is a telltale accompanying sign.

It's also genuinely worth knowing that Kia UK dealers offer an official interior sanitisation service, with a basic disinfectant treatment and a more thorough option including a full cabin filter replacement, worth asking about directly.

Kia Sportage Cabin Air Filter: Easy to Forget, Easy to Fix

Kia Sportage Cabin Air Filter: What It Does

Two filters get mixed up constantly on the Kia Sportage: this one cleans air for the cabin ventilation system, catching dust, pollen and (on activated-carbon versions) some airborne pollutants, while the separate engine air filter deals purely with combustion air. They don't share a part number or a purpose.
