These Pocket Bag Filters are designed for constant flow or air volume, through the pockets of the filter. The moving air “inflates” the pockets, creating a much larger surface area for better filtration.
A filter's MERV (minimum efficiency reporting value) rating measures how efficiently a filter traps contaminants in the air stream based on the size of the particles it can effectively capture. The higher a filter's MERV rating, the more small particles are trapped and removed from the air.
