Car air purifier works against indoor air pollution.  For ordinary people, 80% of their life is spent indoors. The harm caused by indoor air pollution to the human body is far greater than that caused by outdoor air pollution, especially for the elderly, children, pregnant women, patients with weakened immune systems. Their resistance is weak. They spend less time going out, so the quality...

Car air purifier removes PM2.5. The main pollutants we studied were PM2.5, PM10 and sulfur dioxide.   Car air cleaner purifierThe main source of PM2.5 production is the residues discharged from combustion in the process of daily power generation, industrial production, and vehicle exhaust emissions, and most of them contain toxic substances such as heavy metals. Fine particles...

We described both interception and inertia of air filters in the last article. Let’s share another 3 functions, namely diffusion, gravity and electrostatic interaction. Car Air Purifier Refresher PortableDiffusion The Brownian motion of the particles is generated due to the collision of the thermal motion of the gas molecules with the particles, and the smaller the particles,...
