Nordic Pure MERV 14 + Carbon Air Filters are engineered to capture over 90% of airborne particles between 3.0-10.0 microns, effectively filtering out contaminants such as lint, dust, pollen, pet dander, mold spores, and particles from coughs, sneezes, and smog. These filters also remove over 90% of finer particles in the 1.0-3.0 micron range and between 75-95% of ultra-fine particles as small as 0.3-1.0 microns, providing exceptional indoor air quality. With electrostatically charged synthetic materials, each filter includes a durable, moisture-resistant frame and reinforced metal mesh for reliable performance in HVAC systems. Regular filter replacement is recommended to maintain peak air quality and HVAC efficiency, especially in homes with pets or high foot traffic.
