In short, as a device that can improve indoor air quality, air purifiers are of great significance for protecting people's respiratory health and improving their quality of life. When choosing an air purifier, it is necessary to choose according to one's own needs and actual situation, paying attention to indicators such as purification efficiency, filter life, energy consumption and noise. By using air purifiers reasonably, we can create a fresh, healthy, and comfortable indoor environment for ourselves and our families.

Air filters use specific filtering materials to intercept and adsorb harmful substances such as particles, bacteria, viruses, pollen, dust mites, etc. in the air, thereby achieving the goal of purifying the air. Common filtering materials include fiber filter materials, activated carbon, high-efficiency filter paper, etc. They can capture particles of different sizes and effectively improve indoor air quality.
