If you've visited a mechanic in the last 10-20 years, it's fairly likely that you've also been asked to replace a cabin filter at some point as well. Though you can't normally see it, a cabin filter plays a huge part in keeping yourself and whoever travels with you healthy and breathing properly.
While it may seem like a simple thing, a cabin filter is used in almost every car to filter the air that comes through the A/C vents. This simple paper filter makes a world of difference as it stops dust, pollen and debris being sucked into the system and blown straight into your face whilst driving.
As this filter gets blocked or full over time, the filter doesn't work as well as it should and can cause bad smells, headaches, allergies, nausea and even fatigue. Worse than that is that many people forget to check the cabin filter at service, which can lead to some truly horrific things such as wetness in the debris leads to mould or decay, all of which enter the cabin of the car to be breathed in by you.
The cabin filter is usually located on the passenger side behind the glovebox and this difficult access is one of the main reasons it is left unchecked by many owners and mechanics. However, the cabin filter should normally be replaced roughly every 2 years to help keep these nasty particles from being breathed in.
