Air conditioning filters are different from other filters. They focus on providing a good air environment for drivers to ensure that drivers do not inhale external air pollutants as much as possible.
But there are many kinds of air-conditioning filters on the market. What kinds do they have? How to judge the quality of a filter? Next we will answer for you one by one.
There are two types of traditional air conditioning filters:
1.Single-effect air-conditioning filters
Made of synthetic filter material, it can filter particles such as dust and pollen.
2. Dual-effect air conditioning filters
The air conditioning filter with activated carbon is composed of synthetic filter material and activated carbon particles, and has the function of filtering particulate matter and adsorbing odor.
With the continuous improvement of people’s awareness of environmental pollution, there is a higher demand for the driving environment of automobiles. Air conditioning filters with various new functions emerge as the times require, such as anti-haze, anti-PM2.5, anti-bacterial, anti-allergic and other functions.
How to judge the quality of a filter?
- Wind resistance and filtration efficiency
Wind resistance and filtration efficiency are two basic factors determining the quality of air conditioning filters.
High filtration efficiency is naturally a good thing, but if the appropriate filter material is not selected, the increase of filtration efficiency may cause an increase in wind resistance, which greatly affects the air output.
Some manufacturers in order to pursue high filtration efficiency at the expense of air volume, the result is that the cooling and heating effect of air conditioning becomes worse, defrosting, defogging speed decreases, and fuel consumption increases. More serious will cause damage to automotive blowers and evaporators.
- Gas adsorption capacity
It is well known that the quality of activated carbon determines the adsorption capacity of gas. If you don’t choose a high quality activated carbon air conditioning filter, you may smell all kinds of odors, and be harmful to all kinds of gases, such as VOC (volatile organic compounds), such as formaldehyde, toluene and so on.
- dust holding capacity
Dust capacity determines how often the owner changes the air-conditioning filter. When you feel that the air-conditioning output decreases, it means that the air-conditioning filter is dead. At this time, you can consider replacing the air-conditioning filter.
- Other Additional Functions
In addition to the aforementioned factors, air-conditioning filters with multiple protective functions can add a lot of points to the evaluation. While meeting the above performance requirements perfectly, they also bring good news to allergic, susceptible and asthmatic patients.
- Maintenance of air conditioning filter element
Since the function of air conditioning filter is so important, we should pay attention to its maintenance.
(1) Check and clean and replace air-conditioning filters according to maintenance plan.
(2) If the air flow in the vent obviously weakens, the filter element may be blocked. Check the filter element.
(3) In order to prevent damage to the system, make sure that the filter element is installed. If the filter element is not used in the air-conditioning system, the system may be damaged.
