How does an air purifier work?

An air purifier works by removing pollutants and contaminants from the air, thus improving indoor air quality. The process typically involves several stages of filtration and purification, each designed to target specific types of particles and impurities. Most air purifiers start with a pre-filter, which is effective at capturing larger particles such as dust and pet hair. This initial filtration helps prolong the life of more specialized filters that follow. The next stage often includes a high-efficiency particulate air (HEPA) filter. HEPA filters are renowned for their ability to trap very small particles, including allergens like pollen, mold spores, and pet dander, capturing up to ninety-nine point seven percent of particles that are as small as 0.3 microns. In addition to mechanical filtration, many air purifiers incorporate activated carbon filters. These filters are excellent at adsorbing gases and odors, such as smoke and volatile organic compounds, due to the porous nature of the carbon. Some advanced models may also include technologies like ultraviolet light to kill bacteria and viruses or ionizers that emit charged particles to attract pollutants, allowing them to settle out of the air or be caught by the filters. The purified air is then circulated back into the room, creating a cleaner and healthier environment. Regular maintenance, such as changing or cleaning filters, is important to ensure the air purifier continues to function effectively.
