Product Description

Quartz Fiber Filter
Quartz fiber filters are made of very pure quartz fibers with no binders and glass fibers. The pure quartz composition prevents the filters from reacting with acidic gases, unlike glass fiber filters that can react and cause false readings. This makes quartz filters well suited for measuring heavy metal concentrations and small amounts of particles. Because of the low level of alkaline earth metals, ‘artifact’ products of sulfates and nitrates (from SO2 and NO2) are virtually eliminated. Quartz fiber filters are used for air sampling in acidic gases(except HF), stacks, flues and aerosols, particularly at high temperatures and in PM-10 testing as well as where absolute purity of the filter medium is required. The filters also exhibit good weight and form stability.

Membrane Solutions


  • Heat treated for reduction of trace organics and superior chemical purity
  • Filters made of pure quartz micro fiber (SiO2), free of binding elements or additives
  • Higher resistance than glass micro fiber. Very good up to 900 ºC
  • Enables to pass through large volumes of air
  • Binder-free
  • High filtration efficiency
  • Biologically inert with highest chemical and thermal resistance


  • High temperature and hot gas air monitoring applications
  • Applications that require a maximum filter purity with a low metal content and no carbon traces
  • Sampling and analysis of PM 10 particles and other pollutants
  • Pollution controls performed on air in industrial stacks, smoke ducts and aerosols
