Is an In-Car Air Purifier Useful?

[MacAmara]

In-car air purifiers are useful. Here are the relevant details: 1. Filter-based: The principle of filter-based purifiers is similar to that of the car's cabin air filter, using a built-in fan to force air circulation and filter the air through the purifier's filter. This type of air purifier can filter out suspended particles, formaldehyde, and other harmful substances from the air, and it has a simple structure and low cost. 2. Electrostatic: Electrostatic purifiers use static electricity to adsorb dust particles in the air. They operate quietly without generating noise, but their adsorption efficiency is limited, and they cannot purify harmful gases. Additionally, the dust collection plates require regular cleaning, resulting in relatively higher maintenance costs. 3. Negative ion: Negative ion air purifiers generate and release negative ions through a negative ion generator. Since dust, particles, and harmful substances like formaldehyde in the air easily adsorb to negative ions, these harmful substances form larger particles and settle, thereby purifying the air.
