• Media: Water-resistant micro-glass fiber filter media

• Pleat Style: Mini pleated with hot-melt spacing for uniform air distribution

• Frame Materials: Aluminum, galvanized steel, ABS plastic, or MDF

• Seal Types: Neoprene gasket, PU gasket, or gel seal for leak-free installation

• Pressure Drop: Low initial pressure drop for energy-efficient performance

• Faceguard: Optional expanded metal screen on air-entry and exit sides

• Applications: Cleanrooms, hospitals, laboratories, biosafety cabinets, electronics, and precision manufacturing

• Sizes: Standard and custom sizes available

Frequently Asked Questions (FAQs)

1. What is a HEPA Mini Pleat filter?

A HEPA Mini Pleat filter is a high-efficiency air filter using a tightly packed pleat design to increase surface area and maintain compact dimensions. It captures at least 99.97% of airborne particles 0.3 microns in size.

2. Whats the benefit of mini pleating?

Mini pleating increases the media surface area within a smaller footprint, enhancing dust-holding capacity, reducing pressure drop, and extending filter life. It's ideal for systems with limited space.

3. What applications require Mini Pleat HEPA filters?

These filters are widely used in:

• Cleanrooms (ISO 78)

• Pharmaceutical and biotech manufacturing

• Medical facilities and operating rooms

• Electronics production

• Air handling units in sensitive environments

4. How long does a Mini Pleat HEPA filter last?

Typically 13 years, depending on environmental conditions, pre-filtration, and system airflow. Regular monitoring of pressure drop helps determine the best replacement time.

5. Can Mini Pleat HEPA filters be washed or cleaned?

No. These filters are not designed to be washed. Cleaning can damage the media and reduce filtration performance. They should be replaced when efficiency drops or resistance increases significantly.

6. How is the filter tested?

Each HEPA Mini Pleat filter is individually tested using:

• EN 1822 classification (for Europe)

• IEST or ASHRAE 52.2 (U.S. standards)

• Leakage and particle efficiency tests using PAO or DOP methods

7. Are custom sizes or frame types available?

Yes, most manufacturers offer customization in size, frame material, and sealing method (gasket or gel seal) to meet the specific requirements of your HVAC system or cleanroom.

8. Is it suitable for retrofit projects?

Yes, Mini Pleat HEPA filters are often used in retrofits due to their compact design and high performance, especially where space constraints prevent the use of deep-pleat filters.
