High Efficiency Particulate Air (HEPA) Filter

HEPA filter – the Ultimate Protective Barrier for Stringent Cleanroom Requirements

High efficiency particulate air (HEPA) filters are widely used in cleanrooms, operating rooms, biological laboratories, pharmaceuticals, electronics manufacturing, and other industries. They are key equipment for controlling airborne dust, bacteria, and other harmful particles.

  • Sub-HEPA air filters (E10-E12), also known as EPA filters, are primarily used to capture capture particles >0.5 μm, including dust, bacteria, and large airborne particulates.
  • High efficiency particulate air filters (H13-H14), commonly known as HEPA filter, can effectively capture particles with a diameter of 0.3 μm, achieving a filtration efficiency of 99.97% or higher.
  • Ultra-low penetration air filters (U15–U17), referred to as ULPA filters, provide a filtration efficiency of over 99.9995% for suspended particles such as 0.1–0.3 μm microparticles, smoke, and microorganisms.

Filter Materials
Glass Fiber Filter Paper

Glass fiber filter paper is a high-efficiency filtration material made from ultra-fine glass fibers through a wet-laid process. It features a dense, uniform fiber structure with exceptional particle retention capabilities. Widely used in HEPA and ULPA-grade air filters, this material can effectively capture suspended particles with diameters ≥ 0.3 microns, achieving filtration efficiencies of 99.97% or higher.

Besides, it offers low pressure drop, excellent flame resistance, and high-temperature tolerance, making it suitable for cleanroom air purification systems in industries such as pharmaceuticals, biotechnology, electronics, and food processing.

PTFE Filter Paper

PTFE filter paper uses expanded polytetrafluoroethylene (ePTFE) microporous membrane as the filtration medium, offering exceptional chemical inertness and superb hydrophobic properties. With uniform pore size and a stable structure, it effectively filters fine airborne particles while exhibiting excellent resistance to acids, alkalis, corrosion, and high temperatures. It is especially suitable for environments with high humidity, corrosive gases, or extremely high cleanliness requirements – such as biopharmaceuticals, semiconductor manufacturing, and precision instrument laboratories – providing reliable and long-lasting filtration performance for air purification systems.
