Cardboard and Paper Filters

Cardboard and paper exhaust filters use a corrugated or layered cardboard construction to create a baffle-style filtration path that captures paint overspray as exhaust air passes through. Unlike flat fiber media, cardboard baffle filters force air through a series of channels and turns that progressively trap paint particles — achieving high paint arrestance efficiency with a large holding capacity before replacement is needed. They are a practical choice for booths with high spray volumes or operations that want to extend filter change intervals.

Where cardboard filters are used

Cardboard and paper baffle filters are commonly found in high-production automotive refinishing operations, fleet painting facilities, and industrial coating lines where large volumes of overspray are generated and filter longevity is a priority. For lower-volume shops or cost-sensitive operations, fiberglass or polyester pad filters remain the more economical choice.
