Air purifiers use two main types of filters for cleaning air: the HEPA filter and carbon filter. HEPA filters capture particulate pollution like PM2.5 and pollen, and activated carbon filters capture hazardous gases like VOCs and formaldehyde. Learn more about the different types of filters on our Air Purifier Filter Types page.
