Coway air purifiers contain HEPA (High-Efficiency Particulate Air) filters with a MERV Rating of 17 or higher. Our HEPA filters can trap 99.999% of airborne particles of 0.1 ultra microns in size and above. HEPA filters effectively capture particulates such as dust, smoke, pet dander, allergens, odor, and VOCs (Volatile Organic Compounds).
