A system and method of forming fiberglass air filtration media is disclosed which does not require the use of oil additives. A mixture of resin binder, polymer, and dry adhering agent is formed and applied to the fiberglass as it spins onto the drum. Additionally, the fiberglass filtration media density can vary such that the fiber on the air inflow is less dense than the fiber on the air outflow. After oven curing, the finished air filtration media has an improved ability to attract and hold dust and other contaminants.
