Understanding Your Car’s Many Filters

The modern car is loaded with filters. Many things, both liquid and air, need to be filtered – but do you know what your car’s main filters do?

There are four filters that almost every car has: an air filter, a cabin air filter, an oil filter and a fuel filter. Each have a specific purpose.

Air filters and cabin air filters both achieve the same thing – they help with breathing. The cabin air filter is for people. It keeps the air in the cabin clean, free of dust, and prevents smells from entering the cabin. The air filter, however, helps your engine breathe. Cleaner air in your engine means better fuel combustion, better fuel economy, cleaner emissions and smoother rides. Both kinds of air filters are replaced as-needed, but can usually be cleaned multiple times before needing a replacement.

Oil filters are for your motor oil. Oil isn’t just a lubricant but also a detergent. All kinds of gunk and deposits build up in your engine. To make sure your oil can keep cleaning as best as possible, you should replace the oil filter every oil change.

Lastly, fuel filters are for your gasoline. Gunk and fuel don’t mix. A bad fuel filter can result in poor engine performance, or internal engine damage. You should have your fuel filter checked and pressure tested every 15,000 miles and replaced as-needed.
