What Are the Different Types of Car Filters and How Do They Work?

When it comes to car maintenance, there are four main types of filters that need to be changed periodically: oil, transmission, fuel and air. However, some drivers find this confusing because there are two different air filters in most vehicles. Here's more about how each type of filter works (and why you're likely to have two air filters instead of one).The engine air filter is located inside the engine to keep harmful debris away from the system. It has a variety of functions, but arguably the most important one is to work to ensure that your car's engine receives clean air without contaminants.

This air filter prevents potential air pollutants from reaching the car's engine. As the name suggests, this air filter is located inside the engine to keep harmful debris away from the system. The cabin air filter must also be changed periodically, but on a different schedule than the engine air filter. The cabin air filter can be under the hood, behind the glove compartment, or under the dashboard. Depending on their location, cabin air filters can be a little more difficult to replace than the engine air filter.

This filter works effectively to prevent dirt, dust, and environmental contaminants from seeping into and entering the engine. It's important to avoid waiting to change the engine air filter, because if you do, a lot of problems can arise. For example, if you normally drive on dirt roads, drive very frequently with stops and starts, or live in a dry and dusty climate, you may need to change your air filter more often. Like other filters in your car, the fuel filter itself can also become clogged, so many vehicle manufacturers recommend replacing fuel filters regularly. It may seem intimidating to consider evaluating your car's engine air filter, but it's a fairly simple thing that anyone can do. By understanding how each type of car filter works and when it needs to be changed, you can ensure that your car runs smoothly and efficiently for years to come.
