The function of the car air conditioning filter element
The air conditioning filter element of a car is a key component for ensuring the air quality inside the vehicle. Its core functions can be summarized in the following three aspects:
Filter Air pollutants for Respiratory health
Youdaoplaceholder0 Intercept solid particles : such as dust, pollen, grinding particles, etc., to prevent entry into the carriage, to avoid allergic reactions or respiratory diseases.
Youdaoplaceholder0 Adsorbing harmful gases : The filter element containing activated carbon can absorb odors, ozone, carbon oxides (SO2/CO2) and formaldehyde, etc., reducing the concentration of toxic gases.
Youdaoplaceholder0 Sterilizing and Deodorizing : Inhibit bacterial growth, reduce mold-induced sour smell, create a healthy environment.
Protect AIR CONDITIONING system, extend LIFESPAN
Youdaoplaceholder0 Prevent clogging of components Filter impurities to prevent dust accumulation or corrosion of the evaporator, fan motor and maintain system efficiency.
Youdaoplaceholder0 Lower energy consumption : Clean filter reduces fan resistance, indirectly saves fuel or electricity.
Optimizing Driving experience and safety
Youdaoplaceholder0 Anti-fogging glass : Absorbs water vapor to keep vision clear.
Youdaoplaceholder0 Improve cooling/heating efficiency avoid reduced air output due to clogged filter element.
Air conditioning filter
Basic definitions and functions
The automotive air conditioning filter element (also known as the air conditioning filter) is one of the core components of the automotive air conditioning system, mainly used for:
Youdaoplaceholder0 Physical filtration : Intercepts solid particles in the air (such as dust, pollen, abrasive particles, etc.) to protect the respiratory health of drivers and passengers.
Youdaoplaceholder0 Chemical adsorption : The activated carbon type filter element can absorb odors and harmful gases (such as formaldehyde, benzene, sulfur dioxide, etc.), improving the air quality inside the vehicle.
Youdaoplaceholder0 Auxiliary functions : Prevents car Windows from fogging up (by absorbing water vapor), protects the interior of the air conditioning system from contamination.
Main types and structures
Youdaoplaceholder0 Common type :
Material: Usually white single-layer non-woven fabric or environmentally friendly filter material, with a simple structure.
Function: Only basic physical filtering, with a relatively low price.
Youdaoplaceholder0 Activated carbon type :
Material: Double-layer non-woven fabric interlaced with activated carbon particles, compact structure.
Function: It combines physical filtration and chemical adsorption, making it suitable for urban areas or environments with severe odors.
Youdaoplaceholder0 HEPA type :
Material: High-efficiency particulate filter material with relatively high air resistance.
Function: It can filter PM2.5, but it needs to be matched with a strong air conditioning system.
The difference from an air filter element
Youdaoplaceholder0 Air conditioning filter : Filters air entering the vehicle. All models are equipped with it. Located near the glove compartment in the front passenger seat.
Youdaoplaceholder0 Air filter : Only for internal combustion engine models, used to filter air needed for engine combustion, located in the engine compartment.
Replacement and maintenance suggestions
Youdaoplaceholder0 Replacement cycle :
General recommendation: 10,000 kilometers or 1 year (urban environment).
Harsh environment (dusty/hazy) : It needs to be shortened to 3-6 months or 5,000 kilometers.
Youdaoplaceholder0 Maintenance notes :
Do not wash with water or blow with high-pressure air (as it may damage the filter material).
When there is a blockage, compressed air can be temporarily used for cleaning.
Youdaoplaceholder0 Failure Signal : Reduced air volume, unpleasant smell, passenger allergy symptoms, etc.
Youdaoplaceholder0 Summary : The air conditioning filter in a car is a key component for ensuring air quality inside the vehicle. It needs to be replaced regularly according to the environment and frequency of use, especially the activated carbon type is more suitable for areas with severe pollution.
Youdaoplaceholder0 Replacement recommendation : Generally every 10,000-20,000 kilometers or annually, depending on the driving conditions (shorten the cycle in dusty areas). Activated carbon filter element works better, but note that must not be washed with water or blown with high pressure (will damage the structure).
When the air conditioning filter of a car is damaged, the following measures can be taken:
Youdaoplaceholder0 Replace air conditioning filter : If the air conditioning filter is damaged, the most immediate solution is to replace it with a new one. The location of the air conditioning filter varies depending on the vehicle model. Common locations include inside the cabin, under the glove compartment, and behind the glove compartment. The following points should be noted when replacing:
Youdaoplaceholder0 Cabin type : such as the 2017 Lavida, under the black plastic cover plate below the left side of the front windshield. The steps include unscrewing the screws, removing the rubber strips, opening the cover and replacing the filter element .
Youdaoplaceholder0 Glove box type : such as 16 Free light, located at the lower left of the glove box. The steps include opening the baffle, removing the clips, pulling out the old filter element and inserting the new filter element .
Youdaoplaceholder0 Glove compartment rear type : such as the 21 Teana, located at the rear of the glove compartment, requires screw removal and side cover plate removal. The steps include prying open the side cover, removing the screws, gently pulling out the glove box and changing the filter element .
Youdaoplaceholder0 Inspection and maintenance : Regularly check the condition of the air conditioning filter to prevent health problems and equipment failure caused by filter damage. It is recommended to replace the air conditioning filter 1 to 2 times a year based on the usage environment and vehicle mileage. If the vehicle is in a dusty or wet environment, it should be replaced more frequently .
Youdaoplaceholder0 Choose the right filter : When replacing the air conditioning filter, it is recommended to choose products from well-known brands such as MAN, Mahle, Bosch, etc. These brands have higher filtration efficiency and relatively reasonable prices .
Avoid BUYING low price inferior FILTER element, which may affect filtration effect AND equipment life .
