Key Features
⚡ High Efficiency
Extremely high filtration efficiency for particles in the 0.1–0.3 micrometer range (e.g., bacteria, virus carriers, smoke, fine dust). It is a critical final stage for creating a clean environment.
🌬️ Low Resistance
Under the same airflow rate, the pleatless design typically offers lower initial resistance due to more efficient media packing, leading to better energy savings.
🗄️ High Dust Holding Capacity
The optimized structure and high-quality filter media allow it to hold more dust, thereby extending its service life.
📦 Compact Size & Light Weight
Compared to separator filters with the same filtration area, they have a more compact profile and are lighter, facilitating easier installation and maintenance.
🔗 Structure Relies on Adhesive Beads
Its structural integrity depends entirely on uniform and precisely applied hot melt adhesive beads, making the manufacturing process highly demanding. These materials effectively capture dust particles without imposing excessive resistance to airflow. Commonly used materials include glass fiber, synthetic fiber, polypropylene fiber, polyester fiber, and plant fiber. Generally, Mini-pleated HEPA filters use glass fiber.
The Efficiency of HEPA Filter
📊
The efficiency of currently available high-efficiency filters ranges from 99.9% to 99.999999%, and they can be selected based on specific requirements. The rational selection of filter efficiency and face velocity contributes to comprehensive economic benefits.
Structure & Materials
-
🧵Filter Media Typically ultra-fine glass fiber paper. The fibers have an extremely small diameter and are densely packed, capturing particles through various mechanisms like mechanical interception, diffusion, and inertial impact.
-
🛡️End Sealant After folding, both ends of the filter media pack are sealed with polyurethane glue to form solid end panels, preventing unfiltered air from bypassing.
-
🔩Hot Melt Adhesive Beads Replace separators. They bond the filter paper at the peaks and valleys of the pleats, forming stable V-shaped channels. The shape, spacing, and uniformity of these beads directly impact the filter's performance and strength.
-
🏗️Frame Common materials include:
• Galvanized Steel: Most common, offering high strength and moderate cost.
• Aluminum Extrusion: Lightweight and corrosion-resistant, often used in high-demand environments.
• Stainless Steel: Used in highly corrosive or high-hygiene areas (e.g., food processing). -
🔒Gasket Installed around the frame perimeter to ensure an airtight seal between the filter and the housing. Common materials include closed-cell neoprene sponge, polyurethane foam, or silicone gaskets.

Frequently Asked Questions (FAQ)
-
Q1 What is a Mini-Pleated H13 HEPA Air Filter, and how does it differ from standard HEPA filters?A Mini-Pleated H13 HEPA Air Filter uses hot melt adhesive beads instead of traditional aluminum separators to maintain pleat spacing, resulting in a more compact, lighter design with lower initial resistance. It meets the EN1822 H13 classification, achieving filtration efficiency of ≥99.95% for the most penetrating particle size (MPPS), making it ideal for highly demanding cleanroom and sterile environments.
-
Q2 What particle sizes can the Mini-Pleated H13 HEPA filter capture?The Mini-Pleated H13 HEPA filter is highly effective at capturing particles in the 0.1–0.3 micrometer range — the most difficult range to filter. This includes bacteria, virus carriers, smoke particles, ultra-fine dust, and other airborne contaminants, making it a reliable final-stage filtration solution in critical environments.
-
Q3 What industries and environments are best suited for Mini-Pleated H13 HEPA filters?These filters are widely used in electronics manufacturing (semiconductor and LCD cleanrooms), pharmaceutical and bioengineering facilities (sterile drug and vaccine production), healthcare settings (operating rooms and sterile wards), food and beverage aseptic filling rooms, and high-precision research and aerospace cleanrooms where stringent air quality is mandatory.
-
Q4 What frame material options are available for the Mini-Pleated H13 HEPA filter?The filter frame is available in three common materials: Galvanized Steel (most common, high strength, moderate cost), Aluminum Extrusion (lightweight and corrosion-resistant, suitable for demanding environments), and Stainless Steel (ideal for highly corrosive or high-hygiene settings such as food processing facilities). Custom sizing is also supported upon request.
-
Q5 How does the hot melt adhesive bead structure affect filter performance?Hot melt adhesive beads replace traditional aluminum separators to maintain consistent V-shaped channels between pleats. Their shape, spacing, and uniformity are critical — precise application ensures stable airflow distribution, optimal filtration efficiency, and structural integrity under varying operating pressures. Inconsistent bead application can compromise both performance and filter lifespan.
-
Q6 What is the typical filtration efficiency range, and can custom specifications be provided?Currently available high-efficiency HEPA filters offer filtration efficiency ranging from 99.9% up to 99.999999%, selectable based on application requirements. The initial resistance tolerance is ±10%, and custom sizes are supported to accommodate specific installation requirements. Selecting the appropriate efficiency level and face velocity helps achieve the best overall economic and performance outcome.
