Nordic Pure MERV 13 + Carbon Air Filters provide exceptional air filtration, capturing over 90% of airborne particles in the 3.0-10.0 micron range, including common contaminants like lint, dust, pollen, pet dander, and mold spores, as well as particles from coughs, sneezes, and smog. These filters also remove over 90% of finer particles in the 1.0-3.0 micron range and up to 75% of ultra-fine particles down to 0.3 microns. The added activated carbon layer helps neutralize household odors from pets, cooking, smoke, and volatile organic compounds (VOCs). Built with electrostatically charged synthetic media, a durable moisture-resistant frame, and reinforced with metal mesh, these filters are designed for dependable performance in HVAC systems.
