Poor indoor air quality not only affects quality-of-life, but also causes physical discomfort, health issues, and decreased productivity at work. H&V’s cutting-edge Molecular Filter Media (MFM) removes molecules that escape typical HVAC filtration media to dramatically improve indoor air quality.

  • H&V is the leading supplier of gas phase filter media for cabin air, clean rooms, process environments, museums, and comfort air applications.
  • As the only multi-national manufacturer of thin-bed carbon nonwovens, we readily provide engineered solutions for your molecular filtration needs worldwide.
  • Applications

    Molecular filtration is necessary in environments where odor removal and control of harmful VOCs, toxic gases and airborne pollutants are paramount. Airports, hotels, museums, hospitals, home, and cabin-air settings often require this high level of combination filtration.

    Pollution can disrupt technical processes, cause driver and passenger discomfort, and reduce productivity in office and industrial environments. Our patented MFM technologies provide solutions for these filtration challenges and meet air quality and emission standards.

    • Compared to loose carbon media, MFM has higher initial efficiencies at much lower pressure drops.
    • Gas (molecular) and particulate filtration media are combined in one revolutionary, patented air filtration technology.
    • Control and removal of odors, VOCs, toxic gases, and airborne pollutants help avoid health hazards and disruptions of technical processes.
    • For indoor air quality applications, the same filter slot in the HVAC device can be used for both particulate and molecular filtration.

    MFM molecular filtration media achieve higher initial efficiencies and breakthroughs with lower pressure drops. This versatile material has excellent pleatability and processability.
