Air purifiers effectively remove various pollutants, including dust, pollen, pet dander, mold spores, and smoke particles. They also combat odors through activated carbon filters. Some models target volatile organic compounds (VOCs) emitted by household products. While air purifiers may not eliminate all gasses or microorganisms, specialized features like UV-C light or ozone generators can address these. Opt for a high-efficiency HEPA filter and regular maintenance to ensure cleaner indoor air.
