Core Features That Solve Paint Mist Headaches
- Maze Design: Max Capacity, Min Replacements
The winding internal structure doubles the contact area between air and filter media – so it holds 40% more paint mist than standard flat filters. This cuts replacement frequency from 1x/week to 1x/2 weeks (huge time & cost savings for busy spray booths).
- Special Hard Cardboard Frame
Eco-friendly & lightweight: Easy to install/swap (no heavy lifting for your team).
Durable enough for paint booth environments: Resists minor moisture and paint splatters (custom reinforced thickness available for high-use spaces).
- Glass Fiber + Plastic Grid Media (G4 Efficiency)
Glass Fiber Layer: Traps 90% of paint mist droplets (G4 efficiency) – prevents overspray from coating booth surfaces or escaping into the air.
Plastic Grid Support: Keeps the glass fiber media from collapsing under wet paint load – maintains consistent airflow.

Frequently Asked Questions (FAQ)
Q: How often should I replace the DPA filter?
A: Replacement is based on visual inspection and airflow. Typically, replace it when the front faces of the baffles are fully loaded with paint, or when you notice a significant drop in exhaust airflow (the booth door becomes harder to open/pull in). This can range from a week to several months, depending on usage.
Q: Can you make filters for my specific spray booth brand (e.g., Global Finishing, Binks, DeVilbiss)?
A: Yes, absolutely. We regularly produce replacement cartridges for all major spray booth brands. Simply tell us the brand, model, and part number of your current filter, or provide its exact dimensions (L x W x D), and we will manufacture an equivalent or superior product.
Q: Is this filter suitable for both water-based and solvent-based paints?
A: Yes, our standard DPA cartridge is effective for both. The fiberglass media and treated cardboard handle the moisture from water-based paints without disintegrating. For extremely high-volume use with specific paints, we can advise on media density.
