Recently, Auto Lab announced an indicator of 2020 parts of new models and formaldehyde content in the car. According to the “Air Quality Evaluation Guide in Passenger Car”, the in-vehicle air formaldehyde shall not exceed 0.1 mg / m. Therefore, regardless of the overall rankings, as long as it is lower than this indicator, it can meet the national standards.
AUTO LAB testing method is such that each vehicle is placed in a thermostat before testing 12 hours. The instrument used is an industrial grade PPM HTV formaldehyde concentration tester.
Since the vehicle age of the test is not exactly the same, it is basically a state within 1 month to 6 months, and because the frequency and the vehicle use of each car are not So, so the results of the test can only be used as a reference, and the ranking does not have official guiding significance.
In this ranking, the most formaldehyde content in the car is the Eule Good Cat, followed by Tesla Model Y, Lexus UX New energy, Geely Star Rui, Nissan Sylphy, Tank 300, etc. The ranking is the Toyota Asian Dragon, Chevrolet Pioneer, Roewe RX5 Max, Harvard First Love, BMW 3 Series, Honda Gate.
Through this list, we can’t find some characteristics. First, the first is that the rankings of new energy models are generally high. Euli Cat, Tesla Model Y, including the packet 01 Phev, want to ask Xiaopeng P7, 蔚 来 EC6, these new energy cars ranking is relatively high.
The gap between ordinary brands and luxury car brands is not big. There are many luxury brands on this list, but there are also many joint ventures and independent brands. In fact, in terms of air quality in the car, no matter whether it is a luxury brand or a non-luxury brand, in fact, the gap is not so big. Even many independent brands have to lead the luxury brand. 
In the past few years, we can often see many luxury brands are not very good in the air quality in the car. For example, Audi is like Mercedes-Benz, but this Mercedes and Audi is very good. There is no unqualified model.
In the unqualified model, it is a Toyota Asian dragon, Roewe RX5 Max, BMW 3 Series, Honda 3 Series. These cars are still very good in the Chinese market.
In recent years, as consumers pay attention to health, especially after new crown pneumonia epidemic, health is more important to consumers. Before this, consumers are actually not concerned about the quality of the air in the car. Therefore, many manufacturers have neglected research on air quality in the car. The air quality in the car is not very good, becoming the invisible killer of the user.
However, there have been a lot of automakers in recent years to have their own, scent laboratory. By using environmentally friendly materials, the emissions of harmful gases such as formaldehyde in the car are used.
In fact, many car brands are especially valued, safe and healthy Volvo brands, have begun to pay attention to the use of environmentally friendly materials in the car. And also played the classic slogan, open the door, close the door.
Although many car brands have been very good in the air quality in the car, the new car is still suggesting, users buy new cars Thereafter, the window can be opened frequently.
And try to keep the clean and drying in the car. Only in this way can keep the air quality in the vehicle for a long time. Moreover, as the user has the extension of the car time, many hazardous substances in the car will slowly volatilize.
