How Often Should You Replace Your Air Filter?

What is an Air Filter?

Located in the engine bay, the air filter is a necessary part for your car that stops your engine from sucking up unwanted contaminants such as dirt, dust, bugs, etc.  An air filter is not to be mistaken with the pollen filter (otherwise known as the cabin filter). The pollen filter is usually located within the interior of most modern vehicles and keeps dirt, exhaust fumes and debris from entering the air flow of the cabin. Without such, you and your passengers would be at risk of breathing in unclean air.

How often should it be replaced?

It is recommended that most air filters should be replaced every 15,000 - 30,000 Kms or once a year (whichever comes first).  Although, it is best to follow your manufacturer's scheduled servicing. If the filter isn’t replaced it will become dirty and ineffective at filtering out the dirt and debris from entering the engine system. This can affect the engine’s power, performance and your fuel mileage and emissions. 

Most vehicle manufacturers recommend changing your pollen filter every two years. However, if you live in a highly polluted area or drive mostly in the city, this could be more frequent.
