Choosing the right paint booth filter comes down to three questions: which stage of the booth it serves, what media is right for the job, and how your booth moves air. Get those right and you protect your finish quality, your equipment, and your compliance.
1. Know Your Three Filter Stages
- Pre-filters catch large dust and debris at the intake before it reaches the main filter — they extend the life of everything downstream. Shop pre-filters.
- Intake / ceiling filters are the final clean-air stage before air reaches the spray zone. In downdraft booths this is the ceiling blanket. Shop intake/ceiling filters.
- Exhaust filters (arrestors) capture paint overspray as air leaves the booth — this is the stage that must meet the 98% capture rule. Shop exhaust filters.
2. Match the Media to the Job
- F5 tackified polyester — the standard for ceiling intake: 90%+ efficiency, a tackifier that bonds overspray to the media, and a UL 900 Class 1 fire rating.
- Fiberglass pads/rolls — economical coarse exhaust media, good for high-volume or as a first exhaust stage.
- Polyester exhaust media — longer-lasting and higher dust-holding than fiberglass.
- Accordion / paper (Andreae-style) — high-efficiency exhaust media that holds far more overspray than standard pads, often used to meet the 98% rule.
3. Factor In Your Booth's Airflow
- Downdraft: air enters through the full ceiling and exits at the floor/pit — needs ceiling intake blankets plus floor/pit exhaust filters.
- Crossdraft: air moves front-to-back — intake filters at the doors, exhaust at the rear.
- Semi-downdraft: a hybrid, with ceiling intake near the front and rear exhaust.
4. Confirm Compliance
For exhaust, look for a published ≥98% arrestance rating (EPA NESHAP 6H); for intake/ceiling, look for a UL 900 Class 1 or 2 listing (NFPA 33). See our paint booth filter compliance guide for the full picture.
5. Change On Schedule
Replace intake/ceiling filters roughly every 3–6 months (more often in high-volume shops), and change exhaust filters by pressure drop — when your manometer reads outside the booth's spec. Running clogged filters costs you airflow, finish quality, and energy.
