Product Overview
Our glass microfiber filter paper is a non-woven media manufactured from fine borosilicate glass microfibers. It is characterized by an exceptionally high surface area and a complex, porous matrix that enables deep-loading filtration. Unlike conventional materials, it offers a unique combination of high particle capture efficiency (including sub-micron particulates) and low airflow resistance. This media is typically supplied in rolls or sheets and can be pleated, laminated, or treated with binders to meet specific application needs, serving as the essential building block for high-performance filter cartridges, panels, and HEPA/ULPA filters.
Key Features
- Superior Filtration Efficiency: Captures fine dust, aerosols, and micro-particles down to 0.3 microns with high efficiency, forming the basis for HEPA-grade filtration.
- High Temperature Resistance: Withstands continuous operating temperatures exceeding 500°C (932°F), making it ideal for hot gas filtration in processes like incineration or cement production.
- Low Airflow Resistance: Optimized fiber structure ensures high dust holding capacity while maintaining low initial pressure drop, reducing energy consumption.
- Chemical Stability: Inert borosilicate glass composition offers excellent resistance to most acids, alkalis, and solvents, except for hydrofluoric acid and strong alkalis.
- Zero VOC Emission & Fire Resistance: Does not off-gas volatile organic compounds and is inherently non-combustible, ensuring safety in cleanrooms and critical environments.
- Customizable Formulations: Available in various grades, weights, and thicknesses, with options for water-repellent treatments, fire retardants, and composite layers.

Application Scenarios
This versatile media is indispensable across industries where air purity is non-negotiable:
- Pharmaceutical & Biotechnology: Final filtration in sterile filling lines, lyophilizers, and isolators; manufacturing of HEPA filters for cleanrooms and biosafety cabinets.
- Microelectronics & Semiconductor: ULPA filters for chip fabrication cleanrooms, photolithography tool intake, and process gas filtration to eliminate defect-causing particles.
- Nuclear & Aerospace: Critical containment ventilation, glove box exhaust, and filtration for sensitive instrumentation and cabin air systems.
- High-Temperature Process Industries: Hot flue gas filtration in waste incineration, cement kilns, and metal smelting; filter elements for industrial dryers and ovens.
- General Industrial & Manufacturing: High-end HVAC systems, paint spray booth exhaust, powder coating recovery, and compressed air line filtration.
Advantages Over Alternative Media
Choosing glass microfiber paper provides distinct operational and economic benefits:
- Extended Filter Life: The deep-loading characteristic allows for higher dust holding capacity compared to surface-loading synthetic media, leading to longer service intervals and reduced change-out costs.
- Energy Efficiency: The optimal balance of efficiency and low initial pressure drop translates directly to lower fan energy costs over the filter's lifespan.
- Process Integrity: Its inert nature ensures no media-derived contamination, protecting product quality in sensitive manufacturing.
- Total Cost of Ownership (TCO): While the initial media cost may be higher, the combined savings from longer life, energy efficiency, and process protection result in a superior TCO. Our detailed glass microfiber air filter paper pricelist helps you calculate this accurately.

Frequently Asked Questions (FAQ)
Q1: How does the pricing work? Can I get a sample?
A: Pricing is determined by the specific grade, quantity (roll/ sheet dimensions), and any custom treatments. We encourage clients to request our detailed glass microfiber air filter paper pricelist and discuss their application. Free evaluation samples of standard grades are available for qualified B2B inquiries.
Q2: Can this media be pleated?
A: Yes, it is an excellent material for pleating. Its inherent rigidity and strength allow for the creation of sharp, consistent pleats that maximize surface area in cartridge filters. We can supply media with specific stiffness and tensile properties optimized for your pleating process.
Q3: What is the difference between HEPA-grade and standard-grade paper?
A: HEPA-grade paper has a tighter fiber structure and is manufactured under ultra-clean conditions to achieve a minimum 99.97% efficiency on 0.3-micron particles. Standard grades offer high efficiency (e.g., 95-99.5%) but are not certified to the stringent HEPA standard, making them cost-effective for many industrial applications.
Q4: How do I handle and store glass microfiber paper?
A: Store in a cool, dry place away from moisture and direct sunlight. Handle with clean gloves to prevent oil contamination. While strong in tension, the media can be brittle if creased sharply, so care should be taken during handling and conversion.
Q5: Do you offer media with fire-retardant or hydrophobic properties?
A: Absolutely. We offer a range of treated media. Hydrophobic treatments prevent water absorption, ideal for humid environments. Fire-retardant treatments provide an extra layer of safety, though the base glass fiber is already non-combustible. These options are detailed in our product portfolio and glass microfiber air filter paper pricelist.
