How do air purifiers work?

Air purifiers work by removing contaminants from the air in a confined space, thus improving indoor air quality. They utilize various technologies to capture and eliminate airborne particles, including dust, pollen, smoke, pet dander, and even some microorganisms. Most air purifiers consist of several key components that contribute to their efficiency. First, air purifiers typically use a fan to draw in air from the surrounding environment. Once the air enters the unit, it passes through one or more filters. One common type of filter is the High-Efficiency Particulate Air filter, or HEPA filter. HEPA filters are designed to trap very small particles, including allergens and pollutants, capturing at least ninety-nine point seven percent of particles that are as small as 0.3 microns. In addition to mechanical filters, some air purifiers may employ activated carbon filters, which are effective at adsorbing volatile organic compounds and odors, providing a comprehensive approach to air purification. Some advanced models also incorporate technologies like ultraviolet light or ionization, which can target bacteria and viruses. While air purifiers can significantly reduce air pollution within individual rooms or spaces, it is important to understand that they work best in combination with good ventilation and regular cleaning practices.
