Pallflex® Filters
Versatile filters uniquely suited for a broad range of air monitoring applications
  • Can be used for high temperature and hot gas air monitoring applications.
  • Ideal for diesel and other emissions testing required by environmental regulatory agencies.
Tissuquartz™ Filters
  • Heat treated for reduction of trace organics and superior chemical purity.
  • High temperature use for analysis of acidic gases and stack sampling aerosols.
  • High flow rate and filtration efficiency.
  • Ultra-pure soft water processing to reduce residual ion content. (Contact us for typical values.)

Fiberfilm™ Filters

  • Economical filter suited for a range of air sampling applications.
  • Moisture variations in air or gases during air sampling will not cause chemical reactions on the filter.
  • Heat-treated (HT) version available for reduction of trace organics.

Emfab™ Filters

  • Withstands folding for weighing and transport.
  • Every filter flushed with DI water to remove water-soluble residue.
  • Low air resistance for use in critical aerosol sampling tests such as diesel exhaust.
