High-efficiency particulate air filter media for industrial air purification systems
HEPA filter media is a specialized filtration material designed to capture at least 99.97% of airborne particles sized 0.3 microns or larger. It consists of a dense mat of randomly arranged glass fibers or synthetic fibers bonded with a resin binder, creating a tortuous path that traps particles through interception, impaction, and diffusion mechanisms. This component serves as the core filtration element within HEPA filter assemblies used in cleanrooms, pharmaceutical production, electronics manufacturing, and other controlled environments requiring ultra-clean air.

这些分值是采购评估维度示例，不代表真实客户评分、具体国家买家反馈或实时询盘。
HEPA media captures ≥99.97% of 0.3 μm particles, while ULPA (Ultra Low Penetration Air) media captures ≥99.999% of 0.12-0.17 μm particles. ULPA has higher efficiency but also higher pressure drop and cost.
Replacement depends on operating conditions, typically 1-5 years. Monitor pressure drop increase (usually replace when double initial value) and conduct regular integrity testing per ISO 14644 standards.
No, HEPA media cannot be effectively cleaned without damaging the fiber structure. Attempting to clean can create holes and compromise efficiency. They are designed as disposable components.
