Automotive filters: types and purpose

The automobile filter is a very useful part. How long the engine will last without a trip to the car service depends on this mechanism. You can understand the tasks of the barrier system and the varieties of this element by reading this article. After reading you will have no questions about what car filters exist today and what are the benefits for the car. And also you will learn how to choose the right cleaning system for your car.

The right protection against road debris — the air filter

The air filter protects the engine from dust and dirt on the road. It is difficult to overestimate the importance of this element. After all, per 100 km of run the car consumes about 15 cubic meters of atmospheric air. With all its components. That is, including dust, pollution, exhaust gases and more. Not surprisingly, a poor-quality air filter put in the car can cause serious damage. The engine and piston system depend on it. And it simply will not cope with such a load. Therefore, the approach to choosing this system for the car should be very serious.

Car filters

The most common material used to make air filters is cardboard. Sometimes, but very rarely, the cleaner is made in the form of synthetic fibers. For sports car brands, several layers of gauze are used that have absorbed the branded oil. Cardboard and synthetic car filters need to be changed regularly. They come in a variety of shapes. And they can be frameless, panel or cylinder shaped.

Varieties and functions of the oil filter

The oil protector keeps the oil clean by filtering out sediment. It also helps to ensure the right amount of lubrication in the elements of the car after a trip is completed. It is a paper structure and must be replaced as often as the oil is changed.

In terms of appearance, the oil filter can be:

  1. Disassembled, reusable. In such a device, only the cleaning part or cartridge must be replaced.
  2. Non-disassembled, that is, unable to perform its functions after one use. Such car filters need to be replaced as a whole.

They are also classified according to the method of lubricating functions.

Flow-through cleaning

Partial flow (half-flow)


Allows the required amount of oil to be released quickly when starting the engine. These designs are used on most vehicles.

They pass the lubricant through them several times. Each pass cycle cleans a small amount of fuel oil.

Combine flow-through and partially flow-through filtration. Which allows diesel-powered machines to produce maximum filtration.

When choosing an oil cleaner, pay attention to such nuances:

  • What type of fuel you use;
  • The quality of roads (whether it will be asphalt or earthy surface);
  • Make and type of car release.

And with this in mind you should choose a suitable oil filter for your car. After all, the correctly selected device will filter the right nodes with high quality.

What you need to know about the fuel filter

The fuel filter creates a barrier to the entry of various dirt into the mechanisms of the machine. Filtration occurs in two stages. The first is the removal of coarse elements with a diameter of 60 microns or more. And the second stage of fine cleaning prevents the entry of smaller particles, the size of which does not exceed 10 or 15 microns.

Fuel filter

Based on what kind of fuel you use, you need to choose the right cleaner. There are three types of feed, these are:

  • diesel;
  • carburetor;
  • injector.

And accordingly, car filters are installed on them. Let’s break down these types in more detail.




Installed in the gap between the engine and the fuel pump. In such constructions besides filtration of dirt there is also sifting of unnecessary water, the excess of which is extremely undesirable for fuel mechanisms. Elements intended for cleaning the diesel must be replaced very often.

Located near and in front of the carburetor in a transparent design. This allows you to notice the clogging of the cleaner in time and take action. The carburetor system does not need additional filtration, so the most common cleaning systems are installed there.

It is placed under the bottom of the car. It must produce the highest quality filtration. Particles of 10 microns should not get into the system, because the injector type of fuel supply is very sensitive. The cleaning mechanism itself should be made of metal and regularly subjected to quality maintenance.

There is also a cabin car filter that prevents harmful air from entering the cabin. That is, dust, exhaust from the road, nitrogen and sulfur impurities. All those elements that are highly undesirable to breathe. Also, this barrier performs antibacterial functions. The interior cleaning mechanism prevents small elements as small as 1 micron from entering the car.

Now you know what designs for cleaning exist. As well as what you should pay attention to when choosing them. Contact trusted suppliers and check the quality of the material.
