The car air conditioning odor is severe. How to deal with it?

Once the summer heat comes, the frequency of air conditioning use is high. Set the air volume to the maximum and the temperature to the minimum. In exchange for a gust of cold wind, let the burning skin rest for a moment. Wait, how besides the cold wind, there is an odor! Does it seem to be the smell of earth? Also mixed with some plastic smell, a closer smell is not the smell of decay and mold.

First, we need to figure out why there is an odor?

1. continuous heavy rain – the car air conditioning system has a thing called the evaporator, and its role is to say that cooling, all the wind through it will become cold air. If the owner is unfortunate enough to encounter several days of continuous heavy rain, the humid environment will make the evaporator become a breeding ground for mold and fungus. The resulting mold and fungus masses will produce a rotten and moldy smell that will be emitted into the car through the air vents. Not only is it unpleasant to smell, but it is also harmful to your health.

2. long-term smoking in the car – the majority of male compatriots always with a habit that can not be changed. In the traffic jam like to smoke a cigarette to relieve the torment of time. I do not know that the greed for cool, future trouble ah. Most models of the air-conditioning filter are the use activated carbon, which has 100% adsorption capacity on the surface, can effectively remove a large number of odors and harmful gases. However, if you smoke in the car for a long time, it is easy to make the smell of smoke and tar, etc., remain on it, aggravating the odor emitted, resulting in the need to do early maintenance of the air conditioning system.

3. dead insects in the ducts – air conditioning systems have an out, and in, there are insects in addition to the air that comes in. When the external cycle is turned on, many small insects will come in through the external cycle air inlet. These little guys have no return. Their rotten bodies are lying inside the air conditioning ducts and air ducts. There is not only an unpleasant smell but also a lot of harmful bacteria and fungi that will breed.

The solution to the odor problem：

1. buy a bottle of car air conditioning cleaner, must be with a small hose-free type. The basic effects are cleaning, sterilization, deodorization. The price ranges from 9.9 yuan – 100 yuan. 2.

2. air conditioning filter is generally in the passenger glove box inside but also relatively easy to remove. After removing the air conditioning filter can be seen inside, the next direct removal on the line, wait until the cleaning is complete and then replace a new one.

3. find the external air intake, generally in the lower right of the front windshield or close to the engine location. If you can’t find it, you can turn on the air conditioning to the maximum, enable the external circulation; in the vicinity of this piece can feel the air into the place.

Adjust the air conditioning setting to maximum, enable external circulation, and turn on A/C. Then spray the cleaner with the hose attached to the air inlet, spraying for a few seconds and then a few seconds in between, and so on, until only two-thirds of the bottle is sprayed. Keep the cleaner positioned vertically during the spraying period, not horizontally or vertically. After that, turn on each mode of the air conditioner once to ensure that each air duct is cleaned to the entire duration of 10-20 minutes.

5. After the above treatment, turn off the engine. Put the remaining one-third of the cleaner from each air outlet in the car sprayed in. At this time, you will see water drops out from the bottom of the car, that is, the cleaner with the air conditioning condensate discharge.

6. After spraying and leaving it for about half an hour, make sure there is no water discharged from the bottom. Then you can carry out the last step, start the engine, the air conditioning air volume to the maximum, the highest temperature so that the air duct cleaners with high temperature blowing dry is a great success.
