An air purifier is a device designed to remove pollutants and allergens from the air, improving indoor air quality and promoting healthier breathing. These devices use various technologies to capture particles, gases, and other contaminants, providing a cleaner and more comfortable environment for individuals, especially those suffering from respiratory issues or allergies.
Air purifiers work by drawing in air, filtering out impurities, and releasing clean air back into the room. The filtration process typically involves a combination of mechanisms, including HEPA (High Efficiency Particulate Air) filters, activated carbon, and other technologies. HEPA filters, for example, capture 99.97% of particles as small as 0.3 microns, including dust, pollen, and pet dander. Activated carbon, on the other hand, is effective in removing gases, odors, and volatile organic compounds (VOCs).
