An air purifier enhances indoor air quality by removing airborne contaminants like dust, pollen, pet dander, and mold spores. It employs filters or technologies such as HEPA filters, UV-C light, or ionization to capture or neutralize particles. This reduces allergens, pollutants, and odors, providing cleaner air. Air purifiers are beneficial for individuals with respiratory issues and can create a healthier living environment by minimizing the presence of harmful particles, promoting better respiratory health, and reducing the risk of airborne infections.
