On the Kona, if a musty smell persists after a fresh filter, mould further downstream in the evaporator may genuinely be the real cause.

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.

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.

Easy to Forget, Easy to Fix

Unlike most parts covered here, this one has no bearing on how the car drives or performs — its only job is air quality inside the cabin, which makes it very easy to forget about entirely until something 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.

What It Does

The cabin air filter cleans incoming air before it reaches the car's ventilation system, trapping dust, pollen and, on activated-carbon versions, some airborne odours and pollutants. It has no connection to the engine air filter, which is a completely separate part serving the combustion process rather than the cabin.
