Volvo S60 Cabin Air Filter: Intervals, Fitment & Warning Signs

On the S60, a dealer's own extra step, spraying a specific product on the evaporator coil, has genuinely resolved an annual mould smell on related models.

OEM Part Number: 31407748

Accuracy note: confirmed for the current SPA-platform generation — this same part is shared across the S60, S90, V60, V90, XC60, and XC90, since they all ride on the same platform and HVAC architecture.

Cabin air filter, S60 (SPA platform)	Volvo OEM: 31407748 — shared with S60, S90, V60, V90, XC60, XC90; both standard and activated-carbon versions exist under this same reference, so confirm which type you're getting rather than assuming from the part number alone
Cars with IAQS (Interior Air Quality System)	Genuinely require the activated-carbon version to function correctly — the IAQS sensor detects pollutants like carbon monoxide and hydrocarbons, and the carbon filter is what actually absorbs them; fitting a plain paper filter to an IAQS-equipped car means the system detects pollution but can't filter it out, even though the paper filter physically fits the same housing

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.

A Genuinely Useful Piece of Context Worth Knowing About Persistent Smells — Volvo S60 Cabin Air Filter

If a musty smell keeps returning despite regular filter changes, this is genuinely worth knowing: documented cases on related Volvo models describe a dealer resolving an annual mould smell during servicing by spraying a specific evaporator disinfectant product onto the coil, a step distinct from simply fitting a new filter — worth knowing this additional treatment can make a genuine difference.

A genuinely useful technique worth trying: spraying a proper evaporator cleaning foam onto the coil before installing a new filter has been documented resolving a persistent musty smell.

It's also worth knowing an honest access difficulty: pushing the new filter back into place without removing the glovebox entirely is notoriously fiddly on related models.

Warning Signs, DIY Difficulty & Aftermarket Advice

These are the same regardless of make or model — see our full Cabin Air Filter Guide for signs it needs changing, confirming fitment against your VIN, and choosing standard, carbon, or HEPA media.
