What does a pollen filter do?

You might have heard of a pollen filter, or seen it in small print as one of the features of your car.

But what does it do?

The pollen filter (sometimes called a cabin filter) is often put in as a bullet point on the specifications sheet for cars; an afterthought for what people will want in their cars.

The pollen filter helps to remove contaminants from coming in through the air vents – like exhaust fumes from the car in front, dust and dirt on a track or, as the name suggests, pollen flying around during allergy season.

This helps to protect you and your passengers from the bulk of the pollutants and allergens that come with sitting amongst other cars or even off-road where dust and pollen can make your adventure uncomfortable and unpleasant if you have a condition like asthma or hayfever.

Of course, over time, the pollen filter will build up and get clogged with dirt and grime and – because it’s a part of the air conditioning system – will cause your car to smell musty and prevent proper airflow into the cabin.

This means that it’s important to replace your filter every so often to ensure that it’s still working together with your car. Usually manufacturers ask that you replace it every two years, although this can be sooner if you live in a heavily polluted city, or do a lot of driving around cars with dirty exhausts (often in the city, or if you commute on a road with a lot of trucks) or on dusty unsealed roads.

While it isn’t usually covered by capped price servicing, replacing the filter is often an easy job that can be done as an addition to your scheduled service without too much of a hassle for the service technician – although you can check with your service advisor the specific costs to get a pollen filter replaced.

If you think your pollen filter needs replacing, or you just need to bring your car in for a check up, make sure you see our friendly service advisors at our service centres in Moorooka, Springwood or Browns Plains.
