Technical Data & Findings (MERV Rating)
Distinct Dual Density provides maximum dust loading. The course open structure of the white, air-entering layer is designed for depth loading. The green dense downstream layer prevents finer dirt particles from passing through the media.
Unique Adhesive uniformly coats the fibers in the downstream layer during the formation of the media.
Dual-Ply media is a true high performance media. Independent laboratory testing using ASHRAE Standard 52.2 (Method of testing General Ventilation Air Cleaning Devices for Removal Efficiency by Particle Size) classified one inch Dual-Ply as MERV 8 (Minimum Efficiency Reporting Value).
The actual test performance curves show removal efficiencies at various resistance values.
