Use MERV 13 Pocket Air Filters for hospital patient care, general surgery, smoking lounges, and superior commercial buildings. Pocket air filters offer greater dust-holding capacity for longer service life and lower operating costs.
The Minimum Efficiency Reporting Value (MERV) is the efficiency of a filter based on the particle size in microns (0.001mm). 0.30 to 1.0 microns particle size for virus (unattached), carbon dust, seal salt, all combustible smoke, and radon progeny.
Ultrafine Fiberglass Media is specifically designed for each efficiency range.
Synthetic Media does not shed fibers. Use for high-humidity, constant airflow applications.
