1. A vapor adsorbing air intake comprising:
an air intake defining an internal wall surface; and
a sorbent material sheet product that includes a sorbent material sheet and at least one porous cover layer, wherein the sorbent material sheet product is located and positioned along the internal wall surface for interaction with vapors in close proximity thereto,
wherein the sorbent material sheet product has a void volume of about 10% to about 35%, and
wherein the sorbent material sheet comprises a first sorbent having a first butane working capacity (BWC) and a second sorbent having a second BWC, wherein the first BWC is greater than the second BWC.
 
18. A method of capturing vapors in a vapor adsorbing air intake, the method comprising:
providing an air intake defining an internal wall surface and a sorbent material sheet product that includes a sorbent material sheet and at least one porous cover layer located and positioned along the internal wall surface; and
permitting vapors to contact the sorbent material sheet product and thereby be adsorbed by the sorbent material sheet product,
wherein the sorbent material sheet product has a void volume of about 10% to about 35%, and
wherein the sorbent material sheet comprises a first sorbent having a first butane working capacity (BWC) and a second sorbent having a second BWC, wherein the first BWC is greater than the second BWC.
