H13 Mini Pleated HEPA Filter
Product Overview
Mini pleat HEPA filters are designed for terminal filtration in ventilation equipment, dust removal systems, and air supply systems that require high cleanliness. The advanced mini-pleat design and structure ensure effective filtration of airborne particles, suitable for a variety of applications where air quality is critical.
The H13 mini pleated HEPA filter from Guangzhou LJF delivers certified ≥99.95% efficiency at MPPS per EN 1822, with a large specific surface area, even pleat spacing, and stable airflow. Its compact, low-resistance construction saves installation space in FFU grids and AHU terminal housings while keeping energy costs down.
Every HEPA filter is individually tested for integrity before shipment and can be supplied with a test certificate. Choose from seven standard LY-M-H models or request special sizes, with H14 (≥99.995%) also available for stricter requirements.
Key Features
• Large specific surface area — the mini-pleat design provides a larger dust-collecting surface, enhancing overall dust-holding capacity
• Even pleat spacing — ensures consistent airflow and filtration efficiency across the entire filter surface, preventing airflow restriction
• Stable airflow — maintains steady airflow essential for efficient ventilation and air distribution systems
• High filtration efficiency — H13 ≥99.95% at MPPS per EN 1822, capturing dust, pollen, and other airborne pollutants
• Low resistance — minimizes airflow resistance, improving energy efficiency and reducing operating costs
• High temperature resistance — withstands temperatures up to 80 °C for reliable performance
• Moisture resistance — operates effectively in relative humidity up to 100% RH, adapting to different conditions

Applications
• Ventilation equipment — HVAC systems requiring high cleanliness levels
• Dust removal equipment — effectively captures fine dust in industrial environments
• Air supply systems — cleanrooms, laboratories, and medical facilities
• Terminal filtration for spray booth supply air and AHU systems
Maintenance & Service Life
• Replace the HEPA filter when pressure drop reaches the final resistance (typically 2× initial or the rated limit) or when particle monitoring indicates leakage.
• Protect the HEPA with proper pre-filtration (G4/F5–F7 stages) — this extends HEPA service life significantly.
• Handle filters by the frame only; avoid touching the media pleats during installation.
