How often is it better to change the air conditioner filter?
The recommended replacement cycle for automotive air conditioning filters is every 10,000 to 15,000 kilometers or once a year. This cycle can ensure that the filter element is tightly fitted to the housing, preventing unfiltered air from entering the carriage, and effectively isolating solid impurities such as dust, pollen, and abrasive particles in the air to ensure the cleanliness of the air in the car. However, the actual replacement cycle also needs to be flexibly adjusted according to the external environment of the vehicle. If the vehicle is often driven in a humid or foggy environment, it is recommended to shorten the replacement cycle of the filter element.
The frequency of air conditioning use in different seasons will also have a certain impact. For example, in the environment where haze and catkins are more serious, the replacement cycle can be shortened to 15,000 kilometers.
For coastal or humid areas, do not forget to check when the car is regularly checked and maintained, and the replacement mileage is best not to exceed 20,000 km.
In the northern region, the sand is relatively large, it is recommended to check the air conditioning filter once every three months, if there are too many impurities, you need to replace a new air conditioning filter.
In addition, the price of air conditioning filter is not high, if for safety considerations, you can shorten the replacement cycle. Therefore, the owner should adjust the replacement cycle according to their own vehicle environment and frequency to ensure the good operation of the air quality and air conditioning system in the car.
Is the air filter the same as the air conditioner filter?
Air filters and air conditioning filters are not the same:
The role of the air filter is to filter the particulate impurities in the air, ensure that enough clean air is entered into the cylinder, prevent the dust suspended in the air from being sucked into the engine, and accelerate the wear of the piston group and the cylinder. It's on the lower left of the engine room.
Air conditioning filter is to filter the impurities contained in the air entering the interior of the carriage from the outside, small particles, pollen, bacteria, industrial waste gas and dust, etc., to improve the cleanliness of the air and prevent such substances from entering the air conditioning system and damaging the air conditioning system. It's located at the bottom of the passenger glove compartment.
1, air conditioning filter maintenance:
Check and replace air conditioner filters according to the maintenance schedule. In dusty or heavy traffic areas, it may need to be replaced in advance.
If the air flow in the vent is significantly weakened, the filter may be blocked, check the filter and replace it if necessary.
To prevent damage to the system, be sure to install a filter. Using the air conditioning system without a filter may damage the system.
Do not clean the filter with water.
When cleaning or replacing the air conditioner filter, turn off the air conditioning system first.
2, air filter maintenance:
Dry habit-type air filter device is composed of dust cover, guide sheet, dust outlet, dust cup, etc., maintenance should pay attention to: often check and clean the dust hole on the centrifugal dust cover, remove the dust adhering to the guide sheet, pour the dust in the dust collection cup (the amount of dust in the container shall not exceed 1/3 of its volume). Installation should ensure the sealing of the rubber gasket at the connection, there should be no air leakage phenomenon, otherwise the air short circuit, reduce the rotation speed of the air, so that the dust removal effect is greatly reduced.
Dust cover and diversion should maintain the correct shape, and if there is a bump, it should be shaped in time to avoid changing the flow direction of the original design and reducing the filtration effect.
Some drivers add fuel to the dust cup (or dust collector pan), which is not allowed. Because the oil is easy to splash into the dust outlet, the guide plate and other parts, so that this part absorbs dust, and ultimately reduces the filtration separation capacity.
