Exhaust filters are the workhorses of your paint booth — they capture overspray particles before air exits the booth. Properly matched exhaust filters maintain consistent airflow, reduce paint defects, and keep you compliant with EPA and OSHA regulations. We stock fiberglass pads, polyester media, and high-efficiency arrestor panels for all major booth brands.

Frequently Asked Questions

How often should exhaust filters be replaced?

Frequency depends on spray volume — high-production shops may change weekly, while lower-volume shops might go 2-4 weeks. Monitor pressure differential and visual loading.

Can I use aftermarket exhaust filters?

Yes, but quality matters. We supply OEM-equivalent media that meets or exceeds original specifications for capture efficiency and airflow resistance.

What's the difference between fiberglass and polyester exhaust filters?

Fiberglass offers higher initial efficiency and is typically less expensive. Polyester holds more paint before loading and can be better for high-volume applications.
