Cabin filter and air filter are two automotive components with different functions. Although their names are similar, their objects of action and installation positions are completely different.
The cabin filter is mainly responsible for filtering the air entering the car compartment, intercepting pollutants such as pollen, dust and PM2.5, so as to ensure the breathing health of passengers. It is usually installed behind the passenger glove box or near the air-conditioning air inlet. The materials are mostly activated carbon or electrostatic fiber. It is recommended to replace it every 10,000 kilometers or every six months.
The air filter is used to filter the air entering the engine combustion chamber to prevent sand and dust from damaging precision components such as cylinders. It is generally located in the engine compartment and uses paper filter materials. The replacement interval is about 15,000 kilometers.
Although both are filtering devices, the former is for the health of passengers, while the latter is related to the service life of the engine. They need to be maintained separately during routine maintenance. It is worth noting that vehicles frequently driven in sandy or industrial areas should shorten the replacement interval to ensure filtering efficiency.
