If you’ve ever gone for a service and seen two ‘air filter’ line items on your invoice, you may be wondering if you’ve been double charged. You haven’t – your car just has two different air filters that needed replacing. Separate from the air filter in an internal combustion engine, your cabin air filter is responsible for keeping harmful pollutants out of the interior of your car.

In this blog, AGAN shows you how these filters work, and gives you some advice on why and when it should be replaced. Read on and make your next drive more comfortable and breathe easier than ever. 

Filtering more than just pollen

Sometimes tellingly referred to as a pollen filter, cabin air filters trap harmful and irritating pollutants before they can enter the cabin. Like many engine air filters, it’s composed of pleated paper but is generally placed in the outside air intake for the passenger compartment. Some vehicles have the pollen filter within the heater unit and can continuously filter the cabin air at all times.

A god-send for people with allergies or living in very green areas, these filters help you and your passengers avoid unpleasant sneezing and respiratory irritation while driving. If you’re someone who suffers from hay-fever or is particularly susceptible to dust, ensuring your car is free from irritants is something that should be your highest priority.

Why should I replace it?

Keeping your air filter clean and in the best shape is surprisingly important. While your car won’t sputter to a stop if you leave it too long, an old cabin air filter will sharply affect the quality of your driving experience. One symptom of a filter that’s in need of a change is an unusual odour coming from the vehicle’s air vents. This is often described as a dusty, dirty or musty smell, and can make using your air conditioner that much more unpleasant. A blocked pollen filter can also limit the amount of fresh air drawn into the cabin.

When should it be changed and how much will it cost?

Fortunately, changing your pollen filter isn’t something that has to happen every service, nor is it expensive to do. Depending on the environment you drive in and the quality of your filter, you could expect to need a replacement every 15,000 to 50,000 kilometres. Costs can vary but can be as low as $50 for parts and labour.
