When performing routine maintenance on cars, air filters are easily overlooked. In order to avoid premature engine wear and maintain optimal operating conditions, it is important to regularly inspect and replace the air filter.
Before mixing the inhaled air with fuel, the air filter filters out dust, carbon, and debris from the air, ensuring the cleanliness of the inhaled air. When burning fuel per unit volume, approximately 10000 units of air are required to pass through the filter, and even small particles of dirt can cause severe wear and tear on the components.
Usually, manufacturers recommend a replacement cycle of 48000 km for normal maintenance of air filters, and a routine inspection is conducted every 24000 km. The recommended replacement cycle for conservative maintenance is 24000 km.
The atmosphere contains three basic particulate pollutants with different densities, namely dust, residue, and carbon particles. On open highways, the dust content is lower than in rural and built-up areas. In areas with high dust concentrations, the inspection and replacement frequency of air filters should be higher.
During daily oil changes, the air filter can be checked. Remove the filter and carefully examine the depth of its wrinkles inside. Sometimes, the outside of the filter may seem clean, but the inside is already very dirty and must be replaced immediately.
