This high-dust-holding medium-efficiency bag filter media serves as the core filter material for general ventilation bag filters. It features practical upgraded performance and outstanding cost performance. Manufactured via professional gradient needle-punching technology, its base material is premium polypropylene blended with synthetic fibers such as polyester and nylon.

Compared with conventional chemical fiber filter media available on the market, its biggest strengths lie in superior dust loading capacity and stable filtration efficiency. Even after static electricity dissipates, its filtration performance far outperforms ordinary alternatives. The material can be freely cut to fabricate filter bags and assembled with all types of filter frames. Complying with universal domestic and international industry standards, it is an ideal solution for ventilation purification, pre-filtration, and secondary filtration in cleanrooms.

Our Exclusive Core Advantages

  • Ultra-high dust holding capacity, doubled service life Self-developed upgraded formula delivers far greater dust storage than standard media. Less clogging extends filter lifespan, cutting frequent replacement and maintenance costs.
  • Consistent filtration efficiency against operating loss Ordinary media lose efficiency as static fades; ours maintains high precision even after static dissipation for stable long-term performance.
  • Antibacterial & moisture-proof for clean environments Hydrophobic PP base resists dampness, mold and bacteria, ideal for food, pharmaceutical and sterile workshops. Only water and CO₂ released after incineration, eco-friendly.
  • Long-lasting static with no performance decay High-quality electret PP retains static charge well, sustaining high filtration efficiency throughout service.
  • Inherent flame retardancy for superior safety Flame resistance built into the substrate (no surface coating), stable under high temperatures and diverse working conditions for wider application.

Application Scenarios

This filter media comes in three color-coded grades with distinct efficiency levels for targeted ventilation and cleanroom use, avoiding over-specification waste.

  • 30–45% efficiency (white / light green): Basic ventilation filtration for high-traffic public spaces, including commercial buildings, theaters, stations and airports.
  • ~65% efficiency (pink): Medium-grade filtration for spaces requiring moderate air cleanliness, such as paint shops, classrooms and computer rooms.
  • ~85% efficiency (light yellow): High-precision filtration for stringent clean environments. Widely used in petrochemical, plastic, food, pharmaceutical, electronics and military factories. Also serves as secondary cleanroom filtration and pre-filter for HEPA filters in sterile labs and medical clean areas.

Technical Specifications

Conventional synthetic fiber media suffer sharp efficiency drops once static dissipates. Our Whalesense PP HL Series maintains high dust holding capacity even after static loss, delivering a 30% longer service life.
