How Does a Cabin Air Filter Work?

  • How Does a Cabin Air Filter Work? / Transgold

There are plenty of vehicle functions we take for granted, one of which is fresh air when we want it.

To have fresh air inside your vehicle, you need to keep your air-conditioning system in good order and replace your cabin air filter when required.

The purpose of a cabin air filter and where it’s located

A cabin air filter is designed to catch dust particles, pollen and other pollutants to prevent them entering the interior of your vehicle.

As with other filters, it can clog and will need changing from time to time. The location of the filter can vary between makes of vehicles. It might be positioned under the bonnet or dashboard or behind the glove compartment.

Potential signs of a filter problem

While the filter may be checked with your regular vehicle inspection, there are also some signs to watch out for that might indicate your filter is failing.

The first one is an unpleasant odour – either dirty or musty – that becomes more pronounced when the air-conditioning is turned on.

Another sign is poor airflow, with clogging causing the vents to blow with less force and be less effective (the hot or cold functions might only blow warm or cool)

Why you should replace it when needed

A dirty cabin air filter can leave your vehicle smelling terrible, and it can impact the performance of your air-conditioner and defroster. If you want to avoid stale and unhealthy air, then it’s definitely worth keeping an eye on.

Changing the cabin air filter can be a little tricky depending on the make of your vehicle. If you need a new filter or advice on changing one, then feel free to get in touch and our expert dealers will be happy to help!
