Andreae Filter
A spray-booth filter made of two layers of cardboard pleated in opposing directions, giving the airflow inertia so paint particles adhere to the board. Air passes through offset holes in the accordion structure, holding efficiency above 98% depending on the paint or powder. An N-type with polyester non-woven bonded to the lower board raises adhesion further.
