High-Efficiency HEPA Filter Paper: Precision Engineered for Critical Air Filtration

In demanding industrial and commercial environments, air purity is non-negotiable. Our premium HEPA filter paper is the core component engineered to deliver unmatched filtration performance. Manufactured to exacting standards, this specialized media is designed for integration into HEPA and ULPA filters, providing reliable protection for processes, products, and personnel. For OEMs and filter manufacturers seeking consistency, durability, and certified efficiency, our HEPA filter paper is the definitive solution.

Product Overview

Our advanced HEPA filter paper is a non-woven media composed of ultra-fine glass microfibers. It is manufactured through a controlled process to create a dense, random fiber matrix capable of capturing particulate matter with extreme efficiency. This paper meets and exceeds the requirements for HEPA (High-Efficiency Particulate Air) classification as per EN 1822 and IEST-RP-CC001 standards, capable of trapping at least 99.97% of particles at 0.3 microns. It serves as the critical heart of filtration systems across pharmaceuticals, electronics, healthcare, and nuclear containment.

Key Features

• Certified High Efficiency: Guaranteed filtration efficiency of 99.97% on 0.3μm MPPS (Most Penetrating Particle Size).
• Low Air Resistance: Optimized fiber structure ensures high dust holding capacity with minimal pressure drop, enhancing energy efficiency.
• Exceptional Durability: High tensile strength and resistance to humidity and temperature fluctuations ensure structural integrity.
• Fire Retardant Properties: Standard media is inherently fire-resistant, with optional treatments available for enhanced fire safety compliance.
• Customizable Configurations: Available in various efficiencies (H10-H14, U15-U17), basis weights, and with optional water-repellent or bacteriostatic treatments.

Technical Specifications

FAQ

What is the difference between HEPA and ULPA filter paper?

HEPA (High-Efficiency Particulate Air) media is rated to capture 99.97% of particles at 0.3 microns. ULPA (Ultra Low Penetration Air) media is even more efficient, capturing 99.999% of particles at 0.12 microns or MPPS. The choice depends on the required cleanliness class of the application.

Can your HEPA filter paper be pleated?

Yes. Our media is specifically engineered with excellent flexibility and tensile strength to withstand the rigors of high-density mini-pleating and deep-pleating processes without cracking or fiber shedding.

Do you offer fire-retardant or water-resistant treatments?

Absolutely. While our standard HEPA filter paper is inherently fire-resistant, we offer additional fire-retardant coatings. We also provide hydrophobic (water-repellent) treatments for applications with high humidity or risk of moisture exposure.

What certifications do you provide with the media?

We provide material test reports (MTRs) including efficiency, pressure drop, and basis weight. For qualified batches, we can supply IEST-RP-CC001.3 compliant test reports from accredited laboratories upon request.

What are the standard roll dimensions available?

Standard rolls are 1.25m or 1.6m in width and up to 1000m in length. We can customize slitting widths and roll lengths to fit your specific pleating and manufacturing equipment.
