The ideal frequency for changing spray booth filters depends on how often the booth is used, the type of coatings applied, and the working environment. However, as a general guide:

• Intake filters: Replace every 1 to 3 months, depending on airflow and dust levels.
• Exhaust filters: Change every 2 to 4 weeks for high-use booths, or sooner if you notice reduced airflow even after maintenance.
• Pre-filters or secondary filters: Inspect regularly and replace as needed, especially if they appear saturated, to maintain proper airflow.

Tip: Monitor airflow and filter condition regularly. If you notice poor spray quality, uneven airflow, or excessive overspray, it's time to replace your filters.

What Happens If Filters Aren't Changed Regularly?

Failing to replace filters when needed can result in:

• Reduced air quality, posing health risks to operators.
• Contaminated finishes, due to overspray and particles in the airflow.
• Higher energy costs, as the system works harder against clogged filters.
• Compliance issues, with potential environmental or safety violations.

How Do I Know When My Spray Booth Filters Need Replacing?

Watch out for these signs:

• Visible dust, paint build-up, or saturation on filters.
• Noticeable drop in airflow or pressure.
• Increased contamination or imperfections in paint finishes.
• Longer booth clearing times between spray sessions.

Regularly checking and replacing your filters helps maintain a clean, efficient spray environment, and ensures consistent, high-quality results.
