The functions of car air conditioning filters

For most car owners, car air conditioning is no stranger. After all, most cars are equipped with air conditioning systems. Because with it, our trips by car and car will be more comfortable in the hot summer and cold winter. However, when it comes to car air conditioning filters, many people still show a puzzled expression. Some friends even ask what it is. In fact, it works in harmony with the air conditioning system. The cleanliness of the air entering the cabin depends on the quality of the air conditioning filter.

So what is an air conditioning filter and where is it located? Air conditioning filters are generally divided into two types: ordinary air conditioning filters and activated carbon series air conditioning filters. Ordinary air conditioning filters are usually made of a specific environmentally friendly filter material after processing and folding. They are mostly white single-layer but can also be in other colors. The activated carbon series air conditioning filter is made by combining two sides of non-woven fabric (non-woven fabric) with tiny granular activated carbon in the middle to form an activated carbon filter cloth, which is then further processed into an air conditioning filter. The position of the car air conditioning filter is generally installed in the lower glass compartment in front of the passenger compartment of the car. Car owners can also replace it by themselves according to their own conditions because its disassembly, assembly and operation process are all very simple. It can also be replaced by the staff in the 4S store where your car is sold and repaired.

The function of the car air conditioning filter: It filters the air entering the cabin from the outside to improve the cleanliness of the air. Generally, the filtering substances refer to the impurities contained in the air, such as fine particles, pollen, bacteria, industrial waste gas and dust, which enter the air conditioning system and damage it, protect the health of the people in the vehicle, and also prevent the glass from fogging. Ordinary air conditioning filters can only prevent dust and particles from entering. However, the activated carbon series air conditioning filters can, within a very short period of time when the air passes through the flow barrier, utilize the physical properties of granular activated carbon itself to adsorb other tiny substances and more harmful substances in the air. So when making a comparison, the effect of the activated carbon series air conditioning filter is much better than that of the ordinary filter. The replacement time and cycle of the air conditioning filter is generally when the car has traveled 8,000 to 10,000 kilometers. It can also be determined based on the external environment during driving. If the humidity difference in the environment is large, the climate is dry all year round, and there is a lot of sand and wind, it can be replaced in advance.

The relationship between the air conditioning filter and the air conditioning system. When any abnormality is detected in the air conditioning system, the factors that should be comprehensively considered are:

The air conditioner has been set to a high enough setting, but the air volume for cooling or heating is very small. If the air conditioning system is functioning properly, the possible reasons could be that the air conditioning filter has poor ventilation or has been in use for too long. It is necessary to replace it in time.

1. When the air conditioner is working, the air it blows out has an unpleasant smell. The possible reason is that the air conditioning system has not been used for a long time, and the internal system and air conditioning filter have become damp and moldy. It is recommended to clean the air conditioning system and replace the air conditioning filter.

Even if the air conditioning filter has just been replaced and the internal circulation is turned on, it still cannot remove the air odors from both the outside and inside. The reason might be that a regular air conditioning filter is being used. It is recommended to use an activated carbon series air conditioning filter.

The types and materials of air conditioning filters currently available on the market are determined by the original factory air conditioning filters that are installed in the car when it leaves the factory. To put it simply, it's about what kind of air conditioning filter is installed in each car when it leaves the factory. Therefore, the air conditioning filters that are more frequently configured in the aftermarket are those that are exactly the same as those at the factory. Because this needs to take into account the acceptance level of consumers. In fact, whether it is a regular air conditioning filter or an activated carbon series air conditioning filter, the size of the filters installed on the same model of the same year is the same. Therefore, consumers can completely dispel their concerns and not worry about negative effects due to the difference in matching. They can purchase the type they like with confidence.

Researchers from the Hannover Medical School in Germany have found through research that car air conditioning systems can remove over 80% of bacteria, fungal spores and particulate matter from outside the vehicle, which is quite beneficial for people with respiratory diseases and allergic symptoms. However, the researchers also emphasized that the air conditioning systems in the experimental subjects have always been properly maintained and serviced, and the air filters have been replaced regularly. (Here, the air filters refer to the air filters used in car air conditioners, which are commonly known as car air conditioning filters, air conditioning filters, air conditioning filter elements, and air conditioning grilles, etc.) They suggest that car owners check the air conditioning system as soon as they smell a suspicious odor.
