OEM Part Number: 97133-L0000

Accuracy note: genuinely important to know: Kona Electric uses a different reference from the petrol/hybrid Kona, since the electric variant's HVAC layout differs.

Cabin air filter	Petrol/hybrid Kona: 97133-L0000. Kona Electric: 97133-K4000. Also shares the 97133-D3200 reference with related Hyundai/Kia models depending on build year.
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 Honest Diagnostic Point Worth Knowing Before Buying Another Filter — Hyundai Kona Cabin Air Filter

If a musty smell persists even after fitting a fresh cabin filter, this is genuinely worth knowing: mould or mildew can develop further downstream, on the evaporator core or within the ducting itself, meaning a new filter alone won't necessarily resolve it. A genuinely practical technique worth trying: with the filter removed, spraying a mould and mildew treatment down through the empty filter slot while running the blower on medium reaches the evaporator directly.

A genuinely useful, real preventative habit worth building: switching off the air conditioning compressor specifically for the last few minutes of a journey, while leaving the blower running on outside air, helps dry out the evaporator coils before the car sits switched off, reducing the chance of mould developing in the first place.

It's also worth knowing that a sudden, noticeable reduction in airflow can occasionally be caused by debris or a rodent nest blocking the air intake at the base of the windscreen.

Hyundai Kona Cabin Air Filter: Easy to Forget, Easy to Fix

There's no performance downside to a neglected Hyundai Kona cabin filter, which is precisely the problem: nothing about how the car drives will tell you it needs changing, so it often gets forgotten until a musty smell or weak airflow forces the issue.

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.

Hyundai Kona Cabin Air Filter: What It Does

Don't confuse this with the Hyundai Kona's engine air filter — they're unrelated parts. The cabin filter's job is cleaning air before it reaches the ventilation system, catching dust and pollen, with activated-carbon versions also filtering some airborne odours.
