★ Inspection and maintenance of automotive air filters ★
The air filter is working properly. Prevents premature engine wear (abnormal) and maintains optimal working conditions.

Preventive maintenance of air filters is not an exaggeration. Before the intake air is mixed with the fuel, the function of the air filter is to remove dust, carbon, some water vapor and other debris from the air to ensure that clean air enters the cylinder. In theory, about 10,000 unit volumes of clean air are required for each unit volume of fuel to burn. Generally, the manufacturer recommends that the replacement interval for normal maintenance of the air filter is 48,000 km, and a routine inspection is performed every 24,000 km; the recommended replacement period for conservative maintenance is 24,000 km.

The atmosphere contains three basic particulate pollutants of different densities, namely dust, residue and carbon particles. On open highways, its dust content is lower than in rural and building areas. In areas with high dust concentrations, such as construction sites and wind and sand areas, the frequency of inspection and replacement of air filters is higher. On highways and in areas with heavy traffic, the concentration of carbon in the air is significantly higher because of car emissions. The inspection of the filter should be a close look deep inside the folds. Sometimes the outside of the filter looks clean, but the inside is very dirty, and it must be replaced immediately.
