What is a car air conditioning filter element
The automotive air conditioning filter element is the core filtering component of the automotive air conditioning system. It is mainly used to purify the air entering the vehicle, filter out impurities such as dust, pollen, and harmful gases, and ensure the air quality inside the vehicle.
Youdaoplaceholder0 Definition and function of automotive air conditioning filter
The automotive air conditioning filter (also known as the air conditioning filter) is a filtering device installed in the automotive air conditioning system. Its core functions include:
Youdaoplaceholder0 Physical filtration : intercepts solid impurities such as dust, pollen, soot, and grinding particles in the air.
Youdaoplaceholder0 Chemical adsorption : Some filter elements contain an activated carbon layer, which can absorb harmful gases such as odors, formaldehyde, and benzene.
Youdaoplaceholder0 Health protection : Reduce the entry of allergens and bacteria into the vehicle to lower the risk of respiratory diseases for passengers.
Youdaoplaceholder0 Main types and characteristics
According to the differences in material and function, air conditioning filters are divided into two types:
Youdaoplaceholder0 Ordinary non-woven fabric filter element : only has the function of filtering basic particulate matter.
Youdaoplaceholder0 activated carbon composite filter element : By adding an activated carbon layer on the basis of non-woven fabric, it has the ability to adsorb harmful gases and odors.
Youdaoplaceholder0 Replacement and maintenance suggestions
Youdaoplaceholder0 Replacement cycle : It is generally recommended to replace it every 10,000 kilometers or annually, but the specific cycle should be shortened based on the driving environment (for example, in dusty and humid areas, the cycle should be shortened).
Youdaoplaceholder0 Maintenance taboos : Do not wash with water or blow with high-pressure air to avoid damaging the structure of the filter material.
Youdaoplaceholder0 Self-check method : If the air volume of the air conditioner significantly decreases or there is an unpleasant smell, the condition of the filter element should be checked in time.
The core function of a car air conditioning filter is to filter out air pollutants entering the vehicle, while protecting the air conditioning system and enhancing driving and riding comfort.
Youdaoplaceholder0 Core Function Analysis
Youdaoplaceholder0 Air purification function .
Physical filtration: Intercepts dust, pollen, PM2.5 and other particles with diameters greater than 0.3 microns. The HEPA filter core can achieve a filtration efficiency of up to 99.97% for ultrafine particles.
Chemical adsorption: Activated carbon filter cores can remove harmful gases such as formaldehyde, benzene volatile substances, and vehicle exhaust odors.
Biological barrier: Effectively prevents bacteria, mold and other microorganisms from entering the interior space of the vehicle.
Youdaoplaceholder0 system protection function
Youdaoplaceholder0 air conditioning system protection .
Prevent dust accumulation from causing scale formation in the evaporator and avoid a decline in the cooling/heating efficiency of the air conditioner.
Extend the service life of components such as blowers and compressors and reduce maintenance costs.
Reduce the fogging of glass and enhance the safety of driving vision.
Youdaoplaceholder0 health protection value
Youdaoplaceholder0 Crew health maintenance .
Reduce the risk of respiratory diseases: Filter out over 60% of allergens and decrease the occurrence of rhinitis, asthma and other conditions.
Inhibit exposure to carcinogens: Adsorb over 93% of formaldehyde and other Group 1 carcinogens.
Improving the driving environment: Filtered air quality can increase drivers' concentration by 30% and reduce the risk of fatigued driving.
The main manifestations of faults in car air conditioning filters are insufficient air volume, unpleasant odors, and reduced cooling effect. The common causes of faults and their solutions are as follows:
The filter element is clogged
When the filter element is clogged with foreign substances such as willow catkins and dust, it will lead to a reduction in air volume and a decline in cooling effect. The self-check method is:
Youdaoplaceholder0 Weak air volume : Turn on the maximum air volume of the air conditioner. If the air at the outlet is weak or accompanied by a dusty smell, it may be that the filter element is clogged.
Youdaoplaceholder0 Odor : A musty or earthy smell appears inside the vehicle, usually caused by mold or dust accumulation in the filter element.
Youdaoplaceholder0 solution :
Youdaoplaceholder0 Clean or replace the filter element : Remove the filter element from the glove compartment (in most models, it is located behind the passenger glove compartment), and gently tap to remove dust; If the filter element turns black or has a strong unpleasant smell, it needs to be replaced (it is recommended to use an activated carbon filter element).
Youdaoplaceholder0 Installation direction : Pay attention that the arrow of the filter element points to the interior of the vehicle. Installing it in reverse will cause abnormal air volume.
Filter element aging
It is recommended that the air conditioning filter of ordinary family cars be replaced once a year. During periods of poor air quality or high incidence of willow catkins, the replacement time should be shortened to half a year.
Precautions
If there is still an unpleasant smell or refrigeration problem after replacing the filter element, it may involve a blockage in the evaporator or air duct. In such cases, a dedicated cleaning agent should be used for treatment or the device should be sent for repair.
