Nordic Pure MERV 12 Plus Carbon Air Filters are engineered to capture over 90% of airborne particles ranging from 3.0-10.0 microns, including lint, dust, pollen, pet dander, and mold spores, while effectively removing 80-90% of particles as small as 1.0-3.0 microns. Constructed with electrostatically charged synthetic materials, these filters also feature an activated carbon layer that helps reduce common household odors from pets, cooking, smoke, and volatile organic compounds (VOCs). Each filter is built with a moisture-resistant frame and metal mesh support to ensure durability and optimal performance in HVAC systems. Regular replacement is recommended to maintain peak air quality and system efficiency.
