Peugeot Partner Cabin Air Filter: OEM Part Number

Standard particulate filter	PSA Group OEM part, specific to generation — confirm via VIN
Activated carbon version	A genuinely different filter media exists as an alternative to the standard version, confirmed available across the wider Citroen/Peugeot range using compatible fitment

Accuracy note: genuinely worth knowing: this is one of the cheapest parts on the Partner, so there's little downside to buying from a specialist that verifies fitment against your registration or VIN rather than guessing from a generic cross-reference chart.

A Genuine, Well-Documented Cause of Footwell Flooding: Blocked Scuttle Drains — Peugeot Partner Cabin Air Filter

If you've found water pooling in the driver's footwell, particularly after heavy rain, this is genuinely worth checking directly before assuming a coolant leak or heater matrix fault: the scuttle drain holes underneath the windscreen wipers, which are meant to channel rainwater away from the cabin filter housing and out through the wheel arches, are a well-documented blockage point on this platform. When they clog with leaves and debris, water backs up and finds its way through the cabin filter housing itself and into the footwell. In more severe, prolonged cases, standing water in this area has been reported to damage the heater fan's electronic resistance board, turning what starts as a simple blockage into a genuinely more expensive electrical repair if left unaddressed.

A genuinely useful, free DIY fix worth trying first: the scuttle drains can be accessed and cleared without professional help — removing the wiper arms and the plastic scuttle panel trim reveals the drain area, and a coat hanger combined with a toothbrush has been used successfully by several owners to clear years of accumulated grime and leaves from the drain holes. Doing this proactively once a year, particularly before autumn, is a genuinely sensible preventive habit given how disruptive and potentially damaging a full blockage can become.

Worth checking directly if you're also noticing a musty smell alongside any dampness: water sitting in this area for extended periods, even without a full footwell flood, can be enough to introduce a persistent musty smell through the vents — worth ruling out blocked scuttle drains specifically, not just the filter itself, if a fresh filter doesn't fully resolve the smell.

Peugeot Partner Cabin Air Filter: Easy to Forget, Easy to Fix

On the Peugeot Partner, this part sits in an unusual category: neglecting it changes nothing about how the car drives, so there's no natural prompt to replace it. It only affects the air you're breathing inside the cabin, which is why it's so often left well past its interval.

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.

Peugeot Partner Cabin Air Filter: What It Does

Every bit of air blown through the Peugeot Partner's cabin vents passes through this filter first, which is what traps dust and pollen — plus some odours and pollutants if it's an activated-carbon type. It has nothing to do with the engine air filter, a wholly separate component built for the combustion side of things.
