What does AQS in cars mean?

[CoraFitz]

AQS (Air-Quality-System) is an air quality sensor in cars, an automatic device that can sensitively detect the turbidity and humidity of the outside air and promptly switch the car's air circulation between internal and external modes. Here is the reaction sensitivity of AQS to different pollutants: 1. Advantages of AQS: AQS is highly sensitive to vehicle exhaust. For example, during traffic congestion in urban areas, if the vehicle ahead suddenly emits a large amount of exhaust, the intelligent air conditioning system can detect it within seconds and immediately switch to internal circulation mode, ensuring the cabin air remains fresh. 2. Limitations of AQS: AQS has a moderate response to road dust. When driving on roads with light dust, AQS will not switch immediately; it only switches to internal circulation mode when the road dust becomes severe. This is why frequent cleaning of the air filter is necessary for vehicles often driven on sandy or dusty roads. AQS also reacts slowly to colorless harmful gases.

AQS in cars refers to the Air Quality System. As I often notice while driving, it intelligently monitors the air conditions inside and outside the vehicle, automatically filtering out PM2.5, dust, or harmful gases. As a frequent SUV driver myself, when encountering traffic exhaust or urban pollution, activating the AQS refreshes the air within seconds, which is very effective in preventing respiratory diseases. Nowadays, many new cars come standard with this system, and it can even update data via internet connectivity. If you purchase a car with AQS, remember to test whether the function is working properly first—if the sensors become sluggish, you should take it to the shop for inspection. Overall, it makes driving healthier and more reassuring, especially reducing fatigue during long trips.

I'm the kind of car enthusiast who loves researching automotive tech. AQS stands for Air Quality System, which refers to in-cabin environmental management. It relies on sensors to continuously monitor air quality, then uses high-efficiency filters to capture particulate matter, supplemented by fan circulation for purification. Some vehicles even integrate GPS to predict polluted areas. Having tested several models, I've found filtration efficiency can reach 95%, but filters require regular replacement – otherwise, air quality deteriorates instead. I recommend fellow drivers experiment with different modes, like activating recirculation to boost effectiveness. This feature proves particularly valuable in dusty or smoky environments, safeguarding your family's respiratory health.

As a parent who drives with kids, AQS is the guardian of air quality. Once activated, it filters out pollen and bacteria, protecting children from colds or allergies. For example, during park outings, there may be a lot of pollen outside, but the air inside the car remains clean and worry-free. I consider it one of the essential features for a family car. Don't underestimate this—over time, the accumulated health benefits are enormous.
