We strive to make our colors as accurate as possible, but screen images are intended as a guide only. A guideline to keep in mind with the Air Vent Air Hawk is that homes require 1 square foot of net free area (the total unobstructed area through which air can enter or exhaust a non-powered vent) for every 150 square feet of attic floor space. If balanced between intake and exhaust vents, the requirement is 1 square foot of net free area for every 300 square feet of attic floor space.
