Auto filters for beginners: what types of filters are there?

Coffee filters, graphic filters, oil filters ... Filters really exist for everything and in every situation. Whether in everyday life while making coffee or tea, whether at work or as a hobby while editing pictures or driving a car: you will encounter filters everywhere in your life. Sometimes you don't even notice it so directly. Did you know that there are a few filters in your car too? Sure, of course! You probably already know one or the other. But maybe not all. They perform numerous tasks: like a sieve, they hold back solids that must not get into the flow of liquid or air. Curious what is there? Then we will tell you now which types of filters are hidden in your vehicle:

The cabin filter - fresh air

Right now, things are starting again for many of us: our noses are runny, our eyes are puffy and our throats are scratchy. Pollen! In order to guarantee you a pollen-free journey, your cabin filter works for you. But not only pollen, also dirt particles, dust, soot, nitrogen, hydrocarbons or sulfur dioxide - all this stuff is buzzing around in our air. The concentration of pollutants in the street area in particular has increased enormously in recent years. You mean you would be safe from all the bad air in your car? Unfortunately you thought wrong! The load inside the car can even be significantly higher. The reason for this is very simple: through the fan of the fresh air supply or the air conditioning, the polluted air is sucked into your car and distributed in the interior.

Fortunately, you have a good friend in your cabin filter who ensures clean air. In short, its task is to filter pollutants from the ambient air and thereby supply the interior of your car with fresh air.

The air filter - cleaner engine

You don't only need fresh air in your interior to have a pleasant journey. The engine also draws in air. This is of course also contaminated with dirt and dust particles. How dirty the air is depends on the season, the weather, the condition of the road surface and the environment. If the polluted air were to get directly into the engine, signs of wear would become noticeable very quickly. Because dust and dirt act like sandpaper.

In order to counteract these loads, the air filter intervenes here. It is one of the essential components of an internal combustion engine. In summary, his area of ​​responsibility is to clean the air sucked in by the engine. This ensures an optimal combustion process and your engine and downstream engine parts are protected from wear and tear.

The fuel filter - strong fuel

In addition to the air filter, combustion engines also work with the fuel filter. Because for a good trip you don't just need clean air. Of course, the driving fuel must also be free of dirt. In Western Europe in particular, high fuel qualities are now standard. Nevertheless, you can never completely rule out the possibility of dirt particles or water getting into your tank. Here too, dirt particles would lead to wear, for example by clogging the sometimes very small holes in the fuel processing system. Water can lead to corrosion, which in the worst case scenario can bring your engine to a standstill.

So this is where your fuel filter comes in. The bottom line is that it ensures that dirt and water are removed from the fuel. In doing so, it makes an important contribution to the operational safety of your engine.

The oil filter - purified oil

Now you already know two filters that your engine works with - namely air and fuel filters. You haven't had enough yet? Well, let's add one more top: the oil filter. It is also used in modern internal combustion engines. In order to perform at its best, your engine must be well lubricated. Not only does a first-class motor oil play an important role. It also has to be absolutely clean. During the combustion process, dirt particles, soot or combustion residues can get into the oil. This not only makes it dirty, but also thickens it. A perfect oil supply to the engine would no longer be possible. In addition, your fuel consumption would increase and - as always - signs of wear and tear would appear prematurely. In the worst case, there is even a risk of engine damage.

Luckily there is an oil filter. In a nutshell, it ensures clean oil and thus impeccable engine performance. The oil filter also prevents expensive damage.

Your car is optimally equipped with these four filter systems. You will be supplied with fresh air and you can breathe freely. Your engine is also powered to maximum performance with clean air, strong fuel and purified oil. Thanks to the great filters!

Do you ever need new filters in your car? The best thing is to get a few new filters right away and in our next posts we will show you how you can change them yourself. Until then: well filtered trip!
