If you’re hunting for hepa filter paper for sale, here’s the short version: glass microfiber media is still the gold standard when you need reliable H10–H15 (and even U15/U16) performance without drama. I’ve toured a few lines in Hebei and Suzhou over the years; the modern wet-laid processes are steady, and QC has finally caught up with the marketing.
Two big shifts: the ISO 16890 mindset has replaced EN 779 in HVAC pre/secondary, and clean manufacturing (EV battery, pharma, and data centers) is pulling more H13–U15 stock than usual. Lead times are okay (4–6 weeks on average), but custom slit widths can tack on a week. Many customers say the price spread between H12 and H13 is narrower than it used to be—good news if you’re spec’ing up a notch.
Material: glass microfiber | Filter class: F6, F8, F9, H10, H11, H12, H13, H15, U15, U16 | Test standards: EN779 / ISO 16890; HEPA/ULPA verified to EN 1822 / ISO 29463.
| Grade | Efficiency (MPPS) | ΔP @ 5.3 cm/s | Basis weight | Thickness | Width | Max temp |
|---|---|---|---|---|---|---|
| H10–H12 | ≥85–99.5% (≈) | 110–180 Pa (≈) | 75–110 g/m² | 0.35–0.55 mm | ≤1220 mm | ≤120°C (short peaks 150°C) |
| H13–H15 | ≥99.95–99.995% | 150–220 Pa (≈) | 90–130 g/m² | 0.4–0.6 mm | ≤1220 mm | ≤120°C |
| U15–U16 | ≥99.9995–99.99995% | 200–280 Pa (≈) | 100–150 g/m² | 0.5–0.7 mm | ≤1000 mm typical | ≤120°C |
Real-world use may vary by pleat geometry, sealant, and upstream prefiltration.
Borosilicate glass fibers are wet-laid into a uniform web, then binder-impregnated, cured, and calendered for stiffness and low pinhole rates. Slitting and roll inspection follow. Tests: basis weight, thickness, tensile MD/CD, Frazier air permeability, pinhole light scan, and DEHS/PSL efficiency at MPPS per EN 1822/ISO 29463. Service life, honestly, depends on dust load; with proper prefilters, terminal H13 filters run 1–3 years, sometimes longer.
Cleanrooms (ISO 5–8), hospitals and BSL-3 labs, semiconductor and lithium battery rooms, spray booths, negative-pressure units, and even high-end HVAC. For vacuums and cabin filters, grades H10–H12 are common. Pair with F7–F9 prefilters. And yes, hepa filter paper for sale often ships in anti-crush core packs to protect edges—watch out for bruised roll ends.
| Vendor | MOQ | Lead time | Certs | Custom | Notes |
|---|---|---|---|---|---|
| Filtersmaterial (Handan, Hebei) | ≈ 1–3 rolls/grade | 3–5 wks | ISO 9001, RoHS/REACH | Slit width, resin %, roll length | Solid QC; fair shipping rates |
| Global Supplier A | 5+ rolls | 6–8 wks | ISO 14001, 9001 | Wide grades, color tints | Pricier; very consistent |
| Trading House B | 1 roll | Stock/spot | Supplier-dependent | Limited | Check lot traceability |
Quick tip: specify MPPS test agent (DEHS vs PSL) and acceptance ΔP tolerance. It saves back-and-forth. For hepa filter paper for sale in pharma, ask for lot-wise EN 1822 scan data.
Sample H13 lot data (one roll): 99.97% @ MPPS; ΔP 160 Pa @ 5.3 cm/s; pinholes 0; tensile MD/CD 2.1/1.1 kN/m. Looks boringly good—exactly what you want.
