With the outbreak and continuous spread of the COVID-19, people have to pay attention to whether the air they breathe is clean and safe. The importance of automotive air conditioning filter element has been repeatedly mentioned recently. However, some car owners do not use air conditioning filters correctly. Today, let's talk about the mistakes we are prone to make in the process of using and purchasing air conditioner filter elements.

Mistake 1: Long term use of air conditioning filter element
You should know that the air conditioning filter element has a service life. When this part filters the air entering the vehicle, it will be gradually polluted and eventually lose the filtering effect.
When the user feels that the air at the air outlet is obviously weaker than before when using the air conditioner, or the air blown has obvious odor, the filter element of the air conditioner should be checked and replaced in a timely manner.
If the air conditioning filter is used for a long time, the air inlet volume of the air conditioning system will be insufficient due to the blockage of the filter hole, and then the air outlet volume will be reduced synchronously. In addition, if there are leaves or other fermentable pollutants in the air conditioner filter element, the problem of air conditioner odor will soon occur.

Mistake 2: The air conditioning filter element can be reused after cleaning
Although it is often seen that "dirty air conditioning filter elements can be reused after cleaning", professional filter element technical engineers do not recommend this.
At present, the popular cleaning method of air conditioning filter element is nothing more than air flow cleaning or water washing.
First of all, when using high-pressure air flow or large flow vacuum cleaner to remove the dust from the air conditioner filter element, excessive air flow and air pressure will make the diameter of the filter hole in the filter layer larger, which will seriously damage the filtering effect.
Secondly, when cleaning the air conditioner filter element, people usually rub it to remove the pollutants attached to the filter element. External friction will destroy the uniformity of carbon particle arrangement in the activated carbon layer, causing some areas on the filter to lose the ability to remove odor and harmful gases. However, the non-woven fabric after kneading will also be deformed by external forces, making it impossible to put the cleaned filter element back smoothly. Uneven filter installation will leak a large amount of unfiltered air, seriously affecting the filtering effect.

Mistake 3: Many products, choose cheap ones
Friends who often pay attention to auto parts should think that there are many kinds of air conditioning filters in the same car, and the price gap is still large. How should I choose?
First of all, don't just think about cheap, but also choose the formal products of well-known brands. After all, in the narrow space of the vehicle, the air output from the air conditioner almost blows directly on the faces of the drivers and passengers. Therefore, it is necessary to fully filter the air.
In addition, the filter material should also be considered. At present, the air conditioning filter elements are ranked as follows: paper filter elements (basically eliminated, only some old ones are matched), non-woven filter elements, activated carbon filter elements, and enhanced protection filter elements. The specific choice is also decided by the owner according to the frequency of the vehicle's air conditioner and the air quality in the area. When choosing filter element products, we should look for brands, rather than saying that the higher the price, the better the quality, so that consumers do not have to blindly pursue "buying the most expensive".
