What is the function of car negative ions?
2 Answers
Car negative ions are mainly used for sterilization and air purification. The car purifier with negative ion function can adsorb harmful substances in the air, thereby sterilizing and purifying the air inside the car, ensuring the health of drivers and passengers. Relevant information about car air purifiers is as follows: 1. Car air purifiers, also known as vehicle purifiers or in-car air purifiers, consist of components including a circuit negative ion generator, micro fan, air filter system, etc. 2. The working principle is that the micro fan inside the machine circulates the air inside the car. The polluted air passes through the PM2.5 filter and activated carbon filter core, which filter or adsorb various pollutants. Finally, the negative ion generator installed at the air outlet continuously ionizes the air to produce a large number of negative ions, which are then blown out by the micro fan to form a negative ion airflow, thereby cleaning and purifying the air.
After driving for over a decade, I've found this negative ion function in cars quite practical. It mainly purifies the air, especially eliminating odors like smoke, food smells, or new car leather scent by breaking down those odor molecules. I always keep it on during long drives, and it does seem to help reduce drowsiness – probably because those charged particles it generates somewhat mimic forest air. On smoggy days or in heavy traffic with exhaust fumes, it can also adsorb some dust particles. To be honest though, it works best when used in combination with the AC filter; it can't completely replace an air purifier on its own. My friends with rhinitis say they feel much more comfortable riding in my car.
