Nordic Pure Tru Mini Pleat MERV 11 Air Filters have 2.5 times the pleats of standard filters, providing more surface area to trap airborne particles while maintaining optimal airflow. This advanced design improves indoor air quality, extends filter life, and reduces HVAC maintenance costs.  The Tru Mini Pleat filters capture over 94% of particles sized 3.0–10.0 microns, including common pollutants like lint, dust, pollen, pet dander, and mold spores. Additionally, they capture 64-93% of finer particles in the 1.0-3.0-micron range, effectively filtering out smoke particles and certain viruses. Made from durable, electrostatically charged synthetic materials with a moisture-resistant frame, and reinforced metal mesh, ensuring long-lasting HVAC performance and superior air filtration.
