MERV 9 Pocket Air Filters Synthetic Media

Use MERV 9 Pocket Air Filters in high-end residential, commercial buildings, and hospital laboratories. These air filters offer greater dust-holding capacity for lower operating costs and longer service life. Reinforced media-support backing adds to overall filter strength.

The Minimum Efficiency Reporting Value (MERV) is the efficiency of a filter based on the particle size in microns (0.001mm). 1.0 to 3.0 microns particle size for Legionella, lead dust, humidifier dust, coal dust, and nebulizer dust.
Ultrafine Fiberglass Media is specifically designed for each efficiency range.
Synthetic Media does not shed fibers. Use for high-humidity, constant airflow applications.
