What is the purpose of the in-car PM2.5 filtration device?

The function of the in-car PM2.5 filtration device is to filter PM2.5 particles from the air. PM2.5 refers to particulate matter in the atmosphere with a diameter of 2.5 micrometers or less (2.5 micrometers is less than 1/20th the thickness of a human hair). These particles can be inhaled into the lungs and pose significant health risks, especially to sensitive individuals. Below is an introduction to PM2.5-related information: 1. PM2.5, also known as fine particulate matter or fine particles, can remain suspended in the air for extended periods. 2. Higher concentrations of PM2.5 in the air indicate more severe air pollution. Compared to coarser atmospheric particles, PM2.5 has a smaller particle size, larger surface area, stronger activity, and is more likely to carry toxic and harmful substances (such as heavy metals and microorganisms). Additionally, PM2.5 remains in the atmosphere for longer periods and can travel greater distances, thus having a significant impact on human health.
I've noticed many friends complaining about poor air quality while driving, and it really makes a difference after installing a PM2.5 filter in the car. It can intercept those ultrafine particles in the air, such as vehicle exhaust and dust, reducing the pollutants entering the lungs and lowering the risk of asthma or allergies. Especially during rush hour in big cities or in smoky areas, it filters out most of the harmful substances, making our respiratory system more comfortable. People I know, including children and the elderly, all say they breathe more smoothly with fewer coughs and sneezes. Overall, this device improves the health environment inside the car, prevents long-term health issues, and provides a more reassuring driving experience. Personally, I recommend regularly replacing the filter to ensure maximum effectiveness, as pollution is everywhere.
