Automotive air conditioning filter and air filter.
The main difference between automotive air conditioning filters and air filters is their location, function, replacement cycle and the object of protection.
Different location: The air filter element is usually installed in the engine compartment or near the engine, and the specific location can be seen in the car's instructions or maintenance manual. The air conditioning filter is installed in the co-pilot's storage bin.
The main function of the air filter element is to filter the dust and particles in the air entering the engine, to ensure that the engine can inhale fresh and clean air, to avoid sand and dust entering the cylinder to wear the cylinder, and to ensure the normal operation of the engine. The air conditioning filter element is to filter the impurities contained in the air entering the interior of the car from the outside, such as small particles, pollen, bacteria, industrial waste gas and dust, etc., to improve the cleanliness of the air in the car and provide a good air environment for the passengers in the car.
The replacement cycle is different: the replacement cycle of the air filter depends on the amount of dust and impurities, and it is often recommended to replace it once for about 30,000 kilometers when driving on the highway. For urban vehicles, it is generally replaced once in 10,000-15,000 kilometers. The replacement cycle of the air conditioning filter is recommended to be replaced once every six months, and it can also be determined according to the external environment of the driving. If the environment is relatively humid or the haze is high, the replacement cycle can be appropriately shortened.
Different protection objects: the air filter protects the engine, preventing dust and impurities from entering the engine. The air conditioning filter protects the health of the people in the car and prevents various impurities in the air from entering the air conditioning system and affecting the air quality in the car.
To sum up, although both are important automotive filters, they have obvious differences in location, role, replacement cycle and protection objects.
How often does the car air conditioning filter change?
The replacement cycle of the automobile air conditioning filter is usually recommended for a replacement at about 10,000 km. However, this cycle may vary depending on factors such as the vehicle environment, air quality, driving conditions, and filter material. In heavily polluted cities or industrial areas, because there are more harmful substances such as dust and particulate matter in the air, the load of the filter element will be heavier, so it is recommended to shorten the replacement cycle. For vehicles with high mileage or in poor use environments, air conditioning filters may need to be replaced more frequently. In addition, the owner should check the air conditioning filter every other month, according to the use of conditions and environmental factors, it is more appropriate to replace once every six months to a year. If it is found that the cooling or heating effect of the air conditioner is reduced, the air volume is reduced, or there is an odor in the car, it may also be a signal that the air conditioning filter needs to be replaced.
The methods of replacing air conditioning filter elements generally include:
Open the glove box and remove the damping rods on both sides.
Remove the glove box, see the black rectangular baffle, pull it open and remove the card clip.
Take out the old air conditioner filter element.
Install a new air conditioning filter element.
If the air conditioning filter is not replaced in time, the most obvious feeling may be that the car odor is large, affecting driving comfort and air conditioning performance. Therefore, timely replacement of air conditioning filter element is essential to maintain fresh air in the car and driving safety.
Can the car air conditioning filter be cleaned with water?
Better not
Car air conditioning filter is best not to clean with water. Even if the surface looks clean, there may still be a lot of bacteria and dust inside the filter, and the water drop residue is also easy to breed bacteria, resulting in odor in the air conditioning filter.
The material of automobile air conditioning filter is mainly made of non-woven fabric, and some also contain activated carbon particles. If the filter element is only dirty on the surface or there are foreign particles, gently shake it off or blow it off with a high pressure air gun.
If you want to extend the service life of the filter element, it is not recommended to wash it, but to use an air gun for cleaning. However, the effect of this method is limited, and its performance is far less than that of the new filter element. If the pollution degree of the air conditioning filter is serious, it is recommended to replace the air conditioning filter directly.
When replacing or cleaning the air conditioning filter, the following points need to be noted:
If the air flow from the air conditioner is significantly reduced, this may be a signal that the air conditioner filter is blocked, and the filter should be cleaned or replaced in time.
Avoid using water when cleaning, so as not to damage the filter element.
When installing, be sure to follow the direction indicated by the arrow, otherwise the filter element may not work properly, and even blow dust into the car.
In short, in order to maintain the normal operation of the car air conditioning system and the fresh air inside the car, it is recommended to replace the air conditioning filter element regularly, and use the correct method when cleaning is needed.
