Here are the roles and functions of an automotive fresh air system: 1. Role of the fresh air system: The fresh air system refers to a specialized device that filters outdoor fresh air and delivers it indoors while simultaneously expelling indoor polluted air outdoors. This achieves system balance and replaces the air in the compartment, creating a scientific air convection in a confined space, effectively adding a respiratory system to the vehicle. 2. Functions of the fresh air system: Ventilation function supplies fresh air needed for breathing; deodorization function quickly removes unpleasant odors caused by various factors; dust removal function expels floating dust and bacteria from the indoor air; moisture removal function effectively eliminates problems caused by humidity such as condensation, mold, and decay; and it also helps regulate indoor temperature.

When I first started driving, I was fascinated by the car's fresh air system. Its main function is to automatically draw in outside air, filter it clean, and then circulate it into the car, keeping the interior air fresh and free from dust, odors, or exhaust pollution. Functionally, it comes with a bunch of sensors that monitor particulate matter and harmful gases in the air in real-time. If it detects pollutants, it automatically increases the airflow for better filtration. It’s especially useful during traffic jams or smoggy days, helping to prevent motion sickness or allergies from prolonged driving. When I drive in the city, the system kicks in as soon as I close the windows in heavy traffic. It feels healthier than a regular AC, avoiding stuffiness while also deodorizing and sterilizing the cabin—saving me the hassle of manual adjustments. Overall, it’s a great helper for improving driving comfort and health, especially for the elderly and children.

The car air purification system is truly a must-have for urban living! Its function is to improve the in-car air quality by filtering out dirty outside air before circulating it inside, reducing the pollution we inhale. Specific features include real-time monitoring of PM levels and various gases, automatic air exchange cycles that silently activate when air quality is poor; it can also dehumidify and defog, solving issues like winter fogging or summer sweat odors with just a switch. What I love most is its convenience—no need to constantly open windows and breathe exhaust during commutes, as the system activates upon sensing, operating efficiently and quietly, perfectly complementing smart climate control. Long drives feel less fatiguing, with the car's air always fresh and clean.

What kind of glasses can prevent high beams?

Currently, there is no type of lens that can block direct light, as blocking it would render the glasses opaque, making it impossible for the driver to see objects outside. More details are as follows: 1. As for the so-called 'anti-glare glasses' available on the market, they cannot prevent high beams. These glasses can only reduce the glare around direct light, minimizing visual interference, but the effect is limited because high beams are not glare. 2. When driving at night and encountering oncoming vehicles, it is essential not to use high beams, as this is highly uncivilized behavior. You must switch back to low beams in advance when meeting another vehicle; otherwise, it will impair the oncoming driver's vision and pose significant safety risks.
