Paint Booth Filters Explained
Paint booths use two main filters: intake (ceiling) filters that deliver clean, diffused air over the work, and exhaust arrestor pads that capture paint overspray before it reaches the fan and atmosphere. Choosing the right arrestor efficiency protects equipment, ensures finish quality, and supports emissions compliance.
Intake (ceiling) filters
Ceiling filters provide the final cleaning of supply air entering a downdraft or semi-downdraft booth. They must remove fine particles that would otherwise create defects in the finish while maintaining even, low-turbulence airflow across the booth.
Exhaust / overspray arrestor pads
Exhaust arrestors capture paint solids (overspray) so they do not coat the fan, ductwork, and stack. Progressive-density fiberglass and polyester pads load gradually for long life and high holding capacity. Replacing them on schedule keeps booth airflow balanced and protects the exhaust system.
Frequently Asked Questions
How often should paint booth filters be changed?
Intake filters and exhaust arrestors are changed based on pressure drop and visible loading — often every 1–4 weeks in active production. Running loaded filters causes finish defects and unbalanced airflow.
Can paint booth filters be custom sized?
Yes. Ceiling media and arrestor pads are commonly cut to roll or panel sizes specific to each booth. Modern Air Filtration supplies booth media in custom dimensions.
