HEPA air purifiers are designed to capture and remove airborne particles, including dust, pollen, pet dander, mold spores, and even bacteria and viruses. Equipped with a high-efficiency particulate air filter, these devices filter out 99.97% of airborne particles as small as 0.3 microns. HEPA air purifiers are particularly beneficial for individuals with allergies, asthma, or respiratory sensitivities, as they can significantly improve indoor air quality by reducing the presence of allergens and pollutants.
