Fiberglass Air Filter Paper: What’s New, What Matters, and What Works

If you’re shopping seriously for Hepa Filter Paper For Sale, here’s the on-the-ground view from someone who spends far too much time in cleanrooms, HVAC plants, and occasionally dusty warehouses. The headline: microglass media is getting better—tighter fiber control, steadier pressure drop, and more predictable pleating—without wrecking your energy budget.

Product snapshot: Fiberglass Air Filter Paper

Origin: Second Buliding and Studying No21 shiji street, Handan, Hebei China. Material: glass microfiber with precision binder. Filter classes available: F6, F8, F9 (pre/fine), and HEPA/ULPA tiers H10–H13, H15, U15, U16. Tested to EN779/ISO 16890 for coarse/fine ratings; HEPA validation typically per EN 1822/ISO 29463, which I’ll touch on below.

Industry trends (the quick read)

• Electronics and battery plants are pushing toward H13–U15 for yield stability.
• Hospitals and biolabs want lower ΔP to cut fan energy—without losing capture at MPPS.
• More buyers ask for ISO 16890 labeling alongside EN 1822 to align with global specs.

Technical specifications (typical values)

Parameter	Spec (≈/range; real-world use may vary)
Material	Glass microfiber, phenolic/acrylic binder
Grades	F6/F8/F9; H10–H13; H15; U15–U16
Efficiency @ MPPS	H13 ≈ 99.95%; U15 ≈ 99.9995% (per EN 1822/ISO 29463)
Basis weight	≈ 60–120 g/m²
Thickness	≈ 0.3–0.7 mm
Initial ΔP (H13)	≈ 110–180 Pa @ 0.944 m/s (media reference)
Roll width	Standard 1000–1200 mm; custom cuts available
Test standards	EN779/ISO 16890; EN 1822/ISO 29463; ASHRAE 52.2 (as needed)

How it’s made (short version)

Wet-laid microglass slurry → formation on wire → binder addition → oven cure → calendering → porosity tuning → roll slitting → QA. Testing usually includes fractional efficiency at MPPS, Gurley or Frazier air permeability, basis weight, tensile, and pinhole/scan tests. Service life? In cleanrooms, 3–5 years is common; in harsher HVAC, plan 1–3 years depending on dust load and prefiltering.

Where it’s used

• Semiconductor, Li-ion battery, optics (ISO 5–8 rooms)
• Hospitals, ICUs, BSL labs, compounding pharmacies
• Paint booths, food processing, museum HVAC, turbine intakes

Advantages I keep hearing about: stable pleating, low fiber shedding, balanced ΔP vs. capture, and consistent roll-to-roll quality. Many customers say ramp-up scrap dropped after switching media—small changes, big wins.

Vendor landscape (indicative)

Vendor	Grades	Customization	Lead time	Certs	Notes
Hebei FiltersMaterial	F6–U16	Width, basis weight, ΔP targets	≈ 2–4 weeks	ISO 9001; test reports	Strong OEM support
Ahlstrom-Munksjö	Fine to HEPA/ULPA	Broad	Varies	Global labs	Wide distribution
Hollingsworth & Vose	HEPA/ULPA	Engineered media	Varies	Extensive	Premium performance

Customization and testing

Typical options: roll width, basis weight, resin chemistry (temp/humidity profile), targeted ΔP, and pleat geometry compatibility. Expect MPPS scans (ISO 29463), gravimetric efficiency (ISO 16890), and ASHRAE 52.2 where requested. Third-party verification is a plus. Our Hepa Filter Paper For Sale ships with batch QC data; ask for traceable lot reports.

Mini case study

A display-glass coater upgraded from H11 to H13 media in terminal filters using this Fiberglass Air Filter Paper. Result after 90 days: ISO Class improved from 7 (high end) to mid-6 at tool inlets; particle excursions fell ≈ 28%; fan power increase limited to ≈ 6% thanks to lower ΔP media. Maintenance noted cleaner pleat packs at 6-month checks. I guess the takeaway is predictable media saves more than it costs.

Customer feedback: “Surprisingly even pleats after hot-melt bead; no fiber fly.” Another: “Roll-to-roll tension behaves—our pleater tech is happier.” If you need dependable Hepa Filter Paper For Sale for medical or semiconductor work, that kind of boring consistency is gold.

Compliance and documentation

• Standards: ISO 16890, EN 1822/ISO 29463, ASHRAE 52.2
• Quality: ISO 9001; RoHS/REACH statements on request
• Data: MPPS scan curves, ΔP vs. velocity, tensile, porogram

Looking for Hepa Filter Paper For Sale that can scale? Start with your airflow, target class, and energy budget; then dial media basis weight and pleat count together. It sounds obvious, but those trade-offs decide your TCO.
