HEPA Filter Paper Roll
Low Resistance HEPA Filter Paper Manufacturer
We are a professional and advanced manufacturer specializing in glass‑fiber HEPA filter paper. Our optimized glass fiber filter paper production line with a maximum production width of 1.4 meters and an annual output of 30,000 tons. On the basis of mature global manufacturing technology, we have completed a large number of technical optimizations and innovations, making us one of the most advanced glass fiber filter paper manufacturers in China. Currently, our second production line is under steady preparation to further expand large‑scale production capacity and stable global supply capacity.
We support full‑range HEPA filter media production from H10 to H14. Our complete production process and final product performance fully meet EN1822 industry standards. Every batch of filter paper is equipped with complete in‑house test reports (COA) to ensure traceable and reliable quality.
Advanced Production & Strict Process Control
We adopt full‑process intelligent control production. From raw material feeding, vacuum forming, sizing treatment and high‑temperature drying, to online real‑time basis weight inspection and dual high‑speed camera intelligent defect scanning, every production link is precisely monitored.
All finished products will complete full‑item laboratory testing including tensile strength, stiffness, whiteness, water resistance, air permeability, filtration efficiency and pressure drop before slitting, winding and packaging. Strict whole‑process control effectively eliminates batch quality fluctuation.
Core Product Advantages
Energy‑saving & Efficient: Our standard filter paper has 9%‑13% lower pressure drop than ordinary domestic glass fiber media, greatly reducing the energy consumption of terminal filtration equipment.
Stable & Consistent Performance: Precise online process control ensures extremely low fluctuation of air resistance and filtration efficiency between batches, supporting your long‑term stable mass production.
Clean & Safe: The release of benzene series compounds and total volatile organic compounds (VOC) is far lower than ePTFE and other filter materials, with higher safety and cleanliness.
Reliable Batch Quality & Custom Service
All filter media are independently produced in our own factory, no outsourcing sourcing risks. Each roll provides official factory COA test report to support customer sample testing and performance verification. We support customized slitting width, arbitrary roll length and personalized packaging.
Flexible trial order and bulk order policies perfectly meet the procurement needs of filter manufacturers and global trading companies.

Market Challenge & Our Solutions
Challenge
Inferior stiffness and frequent delamination cause deformation or breakage during pleating, compromising filter shape and performance.
Solution
Optimized fiber formulation & 3‑D fiber distribution, plus online formation uniformity inspection. Balanced stiffness and bonding strength for superior pleat‑ability, avoiding deformation and delamination.
Challenge
Loose fibers contaminate the production line, raise defect rate, and force frequent machine cleaning shutdowns, hurting production efficiency.
Solution
Tight 3‑D fiber network suppresses loose‑fiber shedding. Less dust build‑up, lower defect rate and fewer cleaning stops for higher efficiency.
Challenge
Poor bonding with separator glue brings misaligned, collapsed pleats and inconsistent filter geometry.
Solution
Homogeneous material formation ensures stable surface property for good glue adhesion. Great pleat‑ability lowers structural resistance and keeps pleats intact.

QUESTIONS AND ANSWERS
Q1： Can You Cut Flat Before Rolling Up On The Paint Stop Filters?
A1： Most Of The Paint Stop Filters On The Market Are Cut Flat After Rolling Up Because It Is Very Easy Operate, There Will Be A Problem That The Edge Is Not Flat. Certainly, We Can Cut Flat Before Rolling Up, Which Can Be Up To 2.6m Wide.
Q2： How Did You Pack HEPA Filter?
A2： One Unit Is Packed With PE Bag Put In 5-layer Carton. If The Customer Is Worried About The Transportation Process, We Can According To The Requirements Of The Form Of Beating Bracket + Corner Protection + Wrapping Film Packing.
Q3： Have HEPA Filter Passed The DOP/PAO Leak Test?
A3： Sure, Our HEPA Filter Is 100% Able To Pass The PAO Test. Because We Will Do An Integrity Test Of Each HEPA Filter For Efficiency And Leakage Before Shipment And Provide A Corresponding Test Report. Any Leakage Will Be Regarded As Unqualified Products And Reworked. We Are Using MPPS Scan Test For HEPA Filter Integrity Test Which According To EN 1822 Standard.
The Scanning Tracks Will Cover The Area:
Inside Filter Material, Sealant, Filter Frame, Corners, Gasket, Seal Of The Filter Mounting Assembly, The Sealant Between Filter Frame And The Gasket
Q4： How Long Does It Usually Take For Me To Receive The Goods?
A4： Depends On Whether You Want To Do Customization Your Air Filters Or Not, And Depends On The Speed Of Customs Clearance And Logistics, But We Can Guarantee To Ship Regular Air Filter In Less Than 7-10 Business Days, And We Have Customers In Singapore Who Received The Goods In Less Than 2 Weeks After We Ship Out.
Q5： What Is The Standard And Certification Of Your Products?
A5： We Implement Our Production Process In Strict Accordance With The Standards Of EN779 And EN1822.
Q6： What Is The Main Material You Are Using For HEPA Filter?
A6： We Usually Use Mircofine Glassfiber Paper, But We Also Can Do Synthetic Type Nano Paper Or PTFE Paper Type.
