Many people easily confuse air filter with air conditioning filter. They all filter air. What’s the difference between air filter and air conditioning filter? Different positions, different functions and different replacement cycles, but the importance of the two is not equal.
Air filter element and air conditioning filter element are two important parts of automobile. Although they are used to filter air, the former is used to filter air into engine and the latter is used to filter air into cab. One protects the engine, one protects the human.
Air filter element
Location: Open the front hood of the vehicle, usually facing the right side of the engine, as long as the screw on the empty filter box is opened with the screw, you can see the air filter.
Function: The air entering the engine cylinder is filtered carefully to ensure that enough clean air enters the cylinder. Whether it can keep clean and unobstructed is related to the life of the engine.
Replacement cycle: Generally, the vehicle will be replaced once every 10,000 kilometers or half a year. When the haze or willow catkins are serious, it is better to replace the vehicle once every three months. Never wait until the air conditioner in the car is turned on and smells bad before you know the replacement.
Hazard of not replacing in time: If the replacement cycle is exceeded, the filter performance of air filter becomes worse, and the particulate pollutants in the air enter the cylinder directly, which is prone to carbon deposition, resulting in power decline and fuel consumption increase, which will shorten the life of the engine for a long time.
Air conditioning filter element
Location: Open the deputy driver’s locker and remove the baffle to find the air conditioning filter.
Function: Filtrating the air entering the carriage from outside can improve the cleanliness of the air (the filtered substance refers to the impurities contained in the air, such as micro-particulate matter, pollen, bacteria, industrial exhaust gas and dust), which can provide a good air environment for the people inside the car and protect the health of the people inside the car.
Replacement cycle: Under normal circumstances, it is recommended to replace once every six months. It can also be determined according to the external environment of driving. If the environment is relatively humid or haze is high, the replacement cycle can be shortened appropriately.
Harm of not replacing in time: If the replacement cycle is exceeded, the filter element of air-conditioning will absorb a large number of impurities and lose the filtering effect. Over the years, bacteria breed and multiply, seriously affecting the health of passengers in the car.
See here, should be able to easily distinguish between air filter and air conditioning filter! Of course, they are so important that their maintenance or purchase can not be ignored.
Air filters, gasoline filters and oil filters are all aimed at cleaning parts of engine systems, while air conditioning filters are used to ensure the freshness of air in vehicles. Although these four filters are all used to filter impurities, their filtering objects and functions are quite different, and their filtering standards are also very different. In the maintenance, we must strictly follow the replacement cycle in the automobile maintenance manual, and even can be replaced in advance according to the vehicle environment appropriately. In addition, do not be greedy to buy three products at a small price, the final filtering effect is not up to the standard, causing greater losses and trouble!
