(unbranded) Merv Link Air Filter X X Sections Ply Synthetic Media

Start by measuring the filter housing's width and length. The section width must match the housing's width dimension (available in 10, 14, 15, 16, 20, or 22 inches). Then, divide the housing's length by the chosen section width to determine the number of sections needed, ensuring it falls between 2 and 24. For example, a 48-inch length with a 16-inch width would require 3 sections.

Ply refers to the number of layers of synthetic media. A 3-ply filter provides greater structural strength and a higher dust-holding capacity, making it suitable for heavier particulate loads. A 2-ply filter is lighter and may offer lower initial resistance, but with reduced durability. Choose 3-ply for demanding environments or where longer service life is preferred.
