The air conditioning filter is different from other filters. It focuses on providing a good air environment for the driver and occupants in the car, which can ensure that the drivers and occupants do not inhale external air pollutants as much as possible.
But what kinds of air-conditioning filters are on the market? How to judge the quality of a filter? Here we answer one by one for you.

What types of air-conditioning filters are on the market?
There are two types of traditional air-conditioning filters:
Single effect air conditioning filter
Made of synthetic filter material, it can filter particles such as dust and pollen.
2. Double-effect air conditioning filter
That is, the air-conditioning filter with activated carbon is composed of synthetic filter material and activated carbon particles, with the function of filtering particulate matter and adsorbing odors.
As people’s awareness of environmental pollution continues to increase, there is a higher demand for automobile driving environments. Air-conditioning filters with various new functions have emerged at the historic moment, such as anti-fog, anti-PM2.5, and antibacterial , Anti-allergic and other functions.

How to judge the quality of a filter?
1. Wind resistance and filtration efficiency
Wind resistance and filtration efficiency are the two basic factors that determine the quality of air-conditioning filters.
High filtration efficiency is naturally a good thing, but if you do not choose the appropriate filter material, the increase in filtration efficiency may cause the increase in wind resistance, which will greatly affect the air output.
In order to pursue high filtration efficiency, some manufacturers sacrifice air volume at the expense of air conditioning. As a result, the cooling and heating effect of the air conditioner becomes worse, the defrosting and defogging speeds decrease, and fuel consumption increases. More serious will cause damage to the car blower and evaporator.
Gas adsorption capacity
As we all know, the quality of activated carbon determines the level of gas adsorption. If you do not choose a high-quality activated carbon air-conditioning filter, you may smell various odors and be harmed by various harmful gases such as VOC (volatile organic compounds) such as formaldehyde and toluene.
3. Dust holding capacity
The amount of dust holding determines how often the owner changes the air conditioner filter. When you feel that the amount of airflow from the air conditioner is reduced, it means that the air conditioner filter is dead. At this time, you can consider replacing the air conditioner filter.
