If you’re scanning the market for hepa filter paper for sale, you’ve probably noticed two things: prices vary wildly, and the spec sheets can feel like alphabet soup. I’ve toured a few plants, talked with test labs, and—to be honest—cut open more filters than I care to admit. Here’s the practical lowdown on fiberglass HEPA media that buyers actually use to make decisions.
The featured product here is Fiberglass Air Filter Paper (glass microfiber). Grades include F6, F8, F9 (pre/fine) and H10–H13, H15, U15–U16 (HEPA/ULPA). Test standards: EN779/ISO 16890 for coarse/fine and EN 1822/ISO 29463 for HEPA/ULPA. It’s produced in Handan, Hebei, China—Second Building and Studying No.21 Shiji Street, if you like specifics. Many customers say it balances efficiency and pressure drop better than “budget” imports, which tracks with the data I’ve seen.
| Parameter | Typical Range | Notes |
|---|---|---|
| Basis weight | 60–110 g/m² ≈ | Varies by grade (H10–U16) |
| Thickness | 0.30–0.60 mm ≈ | Calendered for uniformity |
| Efficiency | H10–H13 (≥85–99.95% MPPS), H15/U15–U16 (≥99.9995%) | EN 1822 / ISO 29463 |
| Initial ΔP | 90–180 Pa @ 0.053–0.1 m/s | Real-world use may vary |
| Binder system | Phenolic/acrylic hybrid | High temperature stability |
Materials: borosilicate glass microfibers, controlled fiber diameter distribution, and a heat-cured binder. Method: wet-lay forming, dewatering, thermal curing, calendering, and—if ordered—micro-pleatability treatment. Each lot is tested against ISO 16890/EN 779 (for F6–F9) and EN 1822/ISO 29463 (for H/E/U classes). Service life? In cleanrooms, media often lasts 1–5 years, but it’s the dust loading and ΔP limit that really decide the swap-out.
Semiconductor fabs, pharma and biotech cleanrooms, hospital HVAC and isolators, battery plants, food/packaging rooms, and even high-end air purifiers that care about MPPS, not just CADR. For frame makers: the media pleats cleanly with hot-melt spacers or aluminum separators; good stiffness helps avoid pleat tip collapse at higher face velocities.
| Vendor | Grades | Certs | Lead Time | Notes |
|---|---|---|---|---|
| Filters Material (Handan, CN) | F6–U16 | ISO 9001, RoHS/REACH | 2–5 weeks | Strong value; custom widths |
| Ahlstrom-Munksjö | F–U grades | ISO 9001/14001 | 3–7 weeks | Premium branding |
| H&V (Hollingsworth & Vose) | HEPA/ULPA | ISO 9001 | 4–8 weeks | Global support |
Pricing spreads are real; still, MPPS efficiency and uniformity should trump minor cost deltas when you’re buying hepa filter paper for sale.
Battery plant retrofit: H13 media at 99.97% @ MPPS, initial ΔP 120 Pa @ 0.053 m/s; after 9 months, ΔP reached 230 Pa with no pinhole failures (EN 1822 scan), dust holding ≈ 420 g/m². A hospital isolation ward reported quieter fans after switching—small thing, but staff noticed. That’s the kind of real-world signal I trust when comparing hepa filter paper for sale.
Final note: ask for test sheets by lot and insist on EN 1822/ISO 29463 MPPS reporting. If a vendor only quotes “0.3 μm efficiency,” push for MPPS data—it matters.
