Are Car Air Purifiers Effective?

[OElias]

Car air purifiers are effective as they can clean the air inside the vehicle, filtering out bacteria, dust, and absorbing formaldehyde from new cars. Also known as automotive air purifiers or vehicle air purifiers, these devices are specifically designed to purify PM2.5, toxic gases, odors, and bacteria in the car's air. They typically consist of a high-voltage circuit negative ion generator, a micro-fan, and an air filtration system. The working principle of a car air purifier is as follows: the micro-fan inside the device circulates the air in the car. Polluted air passes through the PM2.5 filter and activated carbon filter inside the purifier, where various pollutants are filtered or absorbed. The air is then continuously ionized by the negative ion generator installed at the air outlet, producing a large number of negative ions. These negative ions are blown out by the micro-fan, forming a negative ion airflow that achieves the purpose of cleaning and purifying the air.
