Air filter is the device that can purify air efficiently. I f the dust, sand and a variety of impurities in the air directly into the engine cylinder combustion, they will accelerate the engine wear and tear, thereby reducing the life of the engine and even cause serious damage to the engine.

Air filter is divided into: dry air filter, wet air filter, in which dry air filter is the most commonly used in car models, filter element material is the paper or non-woven. In order to increase the air through the area, most filter element will have many small folds after carefully processed. When the filter is slightly dirty, you can use compressed air blowing, the filter element should be promptly replaced after dirty seriously. In general, the air filter havn’t accurate replacement  time, it is based on the using of the environment to determine, but the replacement time is not more than 1 year, the vehicle travel distance is less than 15,000 km.

There will be problems if air filter replace from time to time  

If the filter block serious, it will increase the intake resistance, the engine power will down. At the same time, as the air resistance increases, it will make the traffic computer increase in the amount of gasoline inhaled, resulting in a thick mixture of gas, so that the engine running state will be deterioration, increase fuel consumption, but also produce carbon deposition.

The consequences of using inferior air filter

Qualified air filter can guarantee the sufficient intake volume to get into engine , and filter out the impurities in the air. Poor quality of the filter element, the production of materials is the poor quality, resulting in air volume is too large or too small, or even can’t achieve the filtering effect, the impurities is easy to enter the engine, making the engine serious wear and tear.

In addition, the life of low-quality air filter is low, generally it will be dirty after using a few hundred kilometers , and also low-quality filter will increase the intake resistance, the engine power will reduce or increase fuel consumption, it easy to produce carbon deposition.
