Pre Filter

Pre-filter is the first-stage air filter used in HVAC systems, cleanrooms, and air purification equipment to remove large airborne particles before the air reaches finer filters like HEPA or ULPA filters.

Key points:

  • Captures dust, lint, hair, pollen, insects, and other coarse particles
  • Typically rated G1–G4 (EN 779) or MERV 1–8 (ASHRAE)
  • Made from synthetic fiber, fiberglass, or nonwoven media
  • Installed upstream of medium or high-efficiency filters
  • Extends the service life of HEPA/ULPA filters and reduces system maintenance
  • Improves airflow stability and lowers operating costs
