A household air purifier is a device specifically designed to remove indoor air pollutants, aimed at improving the cleanliness and quality of indoor air. It usually has multiple functions, such as odor purification, dust removal, sterilization, and formaldehyde treatment, to meet the different needs of air quality in household environments.

Air purifiers, as a device that can effectively improve indoor air quality, are gradually being favored by people. This article will provide you with a detailed introduction to the working principle, classification, selection points, and important role of air purifiers in improving indoor air quality.

Air purifiers mainly use various technical means such as physical filtration, electrostatic dust removal, chemical adsorption, negative ions, etc. to remove pollutants such as particles, bacteria, viruses, and harmful gases from indoor air, thereby improving indoor air quality. Its working principle can be summarized as inhaling indoor air, undergoing multi-layer filtration and purification treatment, and then releasing fresh and clean air back into the room.

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.
