These flat air filters are commonly used to capture large particles between 3 and 10 microns in size (such as mold spores and cement dust).
Non-pleated panel polyester air filters or fiberglass air filters are commonly used in furnace and central air systems in residential and commercial buildings.
A filter's MERV rating measures how efficiently it removes contaminants from the air stream based on the size of the particles it can effectively capture. The higher the MERV rating is, the more effectively the filter traps small particles.
