How often it is necessary to change the filter

The answer to this question is known by professionals who are familiar with the principle of air filter operation. Each manufacturer indicates the recommended filter replacement term in the vehicle's operating instructions. Most automakers regulate the replacement of an air filter every 10 thousand miles. If the car is constantly working in an overly contaminated atmosphere, then the service life is reduced by 1.5-2 times, to 5-7.5 thousand km. Even if the filter is visually clean, but it's time to replace it, it is still worth replacing it.

You can determine if the filter is clogged quite simply - by unstable work of the engine when idle. If the filter is not replaced in time, fuel consumption will increase by an average of 15%.

The filter replacement for car owners with an injector engine is also relevant. In this case, in addition to the increase in fuel consumption, the sensor that indicates fuel consumption starts to fail. The system will not have enough air this will lead to extreme loads that will break the air filter. Hence, air will flow into the cylinders without preliminary cleaning. Malfunction in fuel equipment and pistons will result from this. The cost of untimely replacement of the air filter may be much more expensive than a simple replacement of the filter.

When should you replace the filter then? It's hard to say exact time when you need to change it. Replacing the air filter depends primarily on the vehicle's operating conditions. When traveling on unpolluted and ungarged roads, the air filter does not lose its properties even after running 15 thousand - 20 thousand kilometers. However, if you ride the field roads or, idle in traffic, then the replacement should be done every 8 - 10 thousand kilometers. If you neglect this you can face unpleasant consequences. The worst case scenario is a breakdown of the engine. All you have to do to determine if you need to replace it is to visually examine the filter. If the filter has changed color and has visible contamination, then this filter is better to replace with a new one.

Some interruptions in the motor operation may indicate the need to install a new air filter. Especially, you should pay attention to following:

• reduction of power of the power unit;

• increased fuel consumption;

• detection of carbon monoxide excess concentration in exhaust gases.

If you notice one of the above conditions, then you should inspect the filtering insert for contamination.

As for filters-"zero-markers", the driver can clean them on his own. For this purpose, special solutions have been developed that remove pollution from the filtering material. Under normal operating conditions automobile washing is carried out every 10 thousand km, and when the engine is running in hard conditions it is necessary to clean the "zero" every 5 thousand kilometers. The zero resistance filter can withstand 20 rinses, after which the element can be replaced. How to change the air filter of zero resistance? Its replacement is not much different than replacing the standard cleaner.
