In critical environments like Class 10,000 to Class 100,000 (ISO Class 7–8) cleanrooms, pharmaceutical processing suites, and nuclear exhaust facilities, microscopic contamination can trigger catastrophic batch losses and compliance failures. Substandard filter media frequently suffers from pinhole leakage, binder outgassing, and micro-cracking during pleating—compromising absolute air purity.Our H13 HEPA fiberglass filter paper roll delivers an ultra-consistent micro-porous matrix to ensure zero-bypass performance and uniform air velocity.
Precision Filtration Efficiency: Fully compliant with EN1822 / IEST-RP-CC001 standards, offering 99.97% efficiency at 0.3 μm (customizable from H10 to H14 grades).
High Pleating Integrity: High stiffness and tensile strength prevent micro-cracking and deformation during automated pleating processes.
Cleanroom-Grade Outgassing Control: Formulated with premium non-outgassing binders to meet strict VOC and air purity requirements.
Stable & Predictable Pressure Drop: Optimized 74gsm media weight ensures low initial resistance and extended filter operational lifespan.

Designed for high-consequence containment and strict purity applications, our 0.33mm HEPA fiberglass roll delivers a certified filtration efficiency of ≥ 99.97% at 0.3 µm (tested at 5.3 cm/s face velocity). Operating at an initial resistance of ≤ 330 Pa, it minimizes HVAC fan energy consumption across multi-stage filtration banks.
Non-Outgassing Formulation: Manufactured as a cleanroom-ready non-outgassing HEPA filter paper, using specialized organic binders to prevent chemical off-gassing in sensitive medical and pharmaceutical environments.
Superior Mechanical Pleatability: Features high tensile strength (MD 0.9–1.20 KN/m) and a stiffness rating of ≥ 900 mg, ensuring resistance to pleat deformation and structural vibration under continuous laminar airflow.
100% Quality & EN1822 Tested: Every roll produced in our manufacturing facility undergoes rigorous aerosol integrity testing as DOP tested HEPA glass fiber media, adhering strictly to EN1822 compliance standards.

Our high-efficiency HEPA media roll is engineered to serve as the functional core across a wide spectrum of demanding filtration equipment and controlled environments:
Cleanroom & Industrial HVAC Systems: Essential component for terminal HEPA filter boxes, ceiling diffuser modules, and laminar flow workbenches in ISO Class 7–8 cleanrooms and pharmaceutical manufacturing facilities.
Nuclear Containment Exhaust Assemblies: Trusted for nuclear containment filter assemblies, effectively capturing dangerous airborne radioactive particulates to ensure environmental compliance.
Medical & Personal Safety Devices: Serves as the high-purity barrier inside medical-grade filter units, PAPR respiratory protection devices, and CBRN/toxic gas mask cartridges.
Commercial Appliances & Vacuum Filtration: Widely integrated by OEM appliance brands into commercial air purifier filter packs, HVAC air handlers, and high-performance industrial vacuum cleaners.
Monitoring pressure drop thresholds on bulk HEPA filter media rolls ensures continuous cleanroom compliance, prolongs media lifespan, and protects downstream exhaust blower integrity.
Standard Cleanroom & Commercial Air Purifier Conditions: In controlled ISO Class 7/8 pharmaceutical or electronics environments with proper pre-filtration, conduct monthly static pressure inspections. Replace filter elements when differential pressure reaches double the initial resistance (approx. 600 – 650 Pa) or after 12 – 24 months of operation.
Nuclear Exhaust, Hazardous Containment & Heavy-Duty Operations: In nuclear containment, toxic powder capture, or medical waste exhaust systems, monitor continuous differential pressure with transmitters. Replace media elements immediately upon reaching the design limit (600 Pa) or after 4,000 – 6,000 operational hours to adhere strictly to hazardous material containment protocols.
Frequently Asked Questions
Q: How does your factory verify that this H13 HEPA fiberglass filter paper is leak-free?
A: As a certified HEPA filter paper manufacturer, each batch of our H13 HEPA fiberglass filter paper is subject to strict aerosol photometer testing. We ensure every roll performs as verified DOP tested HEPA glass fiber media achieving ≥ 99.97% efficiency at 0.3 μm.
