Which air filter to choose

Many motorists are choosing an air filter for the car through the sleeves, not counting an important structural element this device. And in vain: air passed through the filter fed directly to the cylinders, and in case of poor cleaning there dust, grains of sand and other debris will fly which will lead on the walls of the scoring cylinder. For this reason, the choice of air filter should be treated as responsibly as possible.

We recommend reading an article from an expert on the selection of oil filter and the secrets of choosing a cabin filter for the car.

Top Air Filter Manufacturers

Experienced car owners recommend choosing to give in favor. air filters manufactured by eminent European and Japanese concerns:

  1. Purflux

  2. Filtron

  3. Knecht

  4. Mahle

  5. Mann

  6. K&N

In order to make the best choice, you must pay attention to the technical characteristics of specific models, as well as on user reviews, taking into account the features, advantages and disadvantages. The latter can be found on the Internet.

Types of Air Filters

The air filter is a plastic frame into which Integrated special filter element. Structure as well The materials used in its manufacture are diverse. IN depending on them, the main types of air filters are distinguished

Traditional air filters

Traditional air filters

The basis of such models is a special porous material, remotely resembling foam rubber. It lets air through easily and prevents dust, sand, debris and moisture from entering the engine. Widely used in modern cars.


  • Inexpensive

  • Variety of models;

  • Good degree of filtration;


  • Requires regular replacement;

  • Do not protect against microscopic particles and chemical compounds;

Carbon filters


More advanced design, high-quality air purification from dust and sand, as well as all kinds of impurities. In addition to synthetic materials and cellulose, the composition includes coal, famous for its absorbent characteristics.


  • Close to maximum degree of purification of air supplied to intake manifold;

  • A large number of various models and sizes;

  • Long service life;


  • More expensive than traditional models;

  • Requires regular maintenance and replacement;

Liquid air filters

Mineral oil is used as a filter element, by which the air entering the intake is cleaned of impurities and dust. Thanks to this design allows repeated use: all that is needed is to replace on time oil.


  • High degree of purification;

  • Easy installation and maintenance;

  • Reusability and the ability to replace the oil yourself;

  • Ease of control over the degree of pollution;


  • More expensive than classic air counterparts;

  • Not suitable for all types of cars;

  • Large net weight;

  • Low air transmittance;

Zero Resistance Filters

Filters of zero resistance

Sports models designed to solve the problem the most efficient air mass supply to the engine cylinders and its high-quality cleaning. Almost always have a round shape and are installed in the standard mount of the air filter at the entrance to intake manifold. Reusable devices cleanable and reusable.


  • Minimum airflow resistance and power gain Consequently;

  • Installed in place of the standard filter;

  • High quality workmanship;

  • Allow multiple use;


  • Shortened cleaning and maintenance intervals;

  • High price;

Air Filter Selection Options

air filter selection criteria

Having decided on a specific device class, you must pay close attention to technical subtleties and features design of a particular filter.

Filter capacity

Measured in liters and displays the volume passing through the insert air for a specific point in time. This parameter must be as close as possible to the original, otherwise it rises the probability of getting a lack of intake air and improper mixture formation;

Degree of filtration

It is displayed as a percentage and indicates the amount of impurities, which this or that filter is able to stop. Higher value is better. For modern cars, the value is 90% is the minimum acceptable threshold. Fewer filters automatically become a threat of scoring on the walls cylinder and engine failure.

The integrity of the filter element and its quality execution

Any clearance not provided by the manufacturer or violation structural integrity automatically increases skipping abrasive substances past the filter. It is for this reason that quality and integrity insertion should be given the utmost attention.

The minimum size of the filtered fraction

Even the smallest speck of dust that can cause badass in the cylinder, has a certain size. Manufacturer task – ensure a balance between the free passage of air through filter and maximum allowable filtration. Optimal are considered filters capable of retaining particles up to 1 micrometer.

Parameter independently determined by each manufacturer filter. You should not believe the indicated numbers: even if on the package as a frequency, figures are displayed every 30-40 thousand, the interval should be reduced by at least half. In the case of heavy operating conditions – three times.
