People are paying more and more attention to air quality. Some even hope that mobile phones will have air detection functions to monitor the air quality around them in real-time to take necessary measures promptly. Private cars have become the first choice for travel, which has led to discussions about automotive environmental protection and fresh air inside vehicles. The Luftmy editor understands that to detect the concentration of harmful gases, air quality sensors and other gas sensors are required. These sensors convert the tested concentration into corresponding digital standards so that users clearly know the surrounding air quality. These are also particularly important in the field of automotive sensors. So, what kinds of pollution exist inside a car?

1. The new car itself

New cars often enter the market directly after leaving the production line. There is no release period for harmful gases and odors from various parts and materials. If plastic parts, carpets, roof felts, and sofas installed in the car do not meet strict environmental requirements, they will directly cause in-car air pollution.

2. In-car air pollution

Poor air quality situations inside cars are caused by factors such as lack of ventilation and vehicle interior decoration. Luftmy's editor has learned that in-car air pollution sources mainly come from the vehicle body itself and decorative materials, among which toxic substances like formaldehyde, xylene, and benzene have the most serious pollution consequences.

3. Outdoor air pollution

When the outdoor air quality is poor, the air inside the car will be affected accordingly. In addition, exhaust on the road, PM2.5, industrial dust, and bacteria are all sources of pollution, which can be detected through detectors equipped with dust sensors.

4. Vehicle air conditioning evaporator

If the vehicle air conditioning evaporator is not cleaned and maintained for a long time, a large amount of dirt will attach to its interior. Harmful substances such as amines, nicotine, and bacteria produced will permeate the small space inside the car, leading to poor air quality or even oxygen deficiency. Luftmy's editor has learned that because the car space is narrow and new cars have good sealing, air circulation is poor and the initial air volume is low. Coupled with serious cross-contamination among passengers, harmful gases exceeding the standard in cars can be more harmful to the human body than those in houses.

5. Smoking in the car

If the driver or passengers smoke, it will not only significantly increase the levels of air pollutants such as volatile organic compounds, carbon monoxide, and dust, but the emitted odor may also remain in the cabin for a long time.

6. Car interior decoration

Interior decoration is a favorite for many, but the toxic gases contained in these decorative materials mainly include benzene, formaldehyde, acetone, and xylene.

These pollutants are invisible to the naked eye. The Luftmy editor reminds that when we can smell them, it means the concentration is already quite high. This can only be effectively detected with the help of automotive air quality sensors, which can detect pollutants and display them through a digital panel. Then, combined with the use of an in-car air purifier equipped with a vehicle PM2.5 sensor, air quality can be monitored and addressed at any time.
