We designed the polytech Filter with two primary purposes in mind - one to provide an effective barrier to potential contaminants while not interfering with the accuracy and precision of the pulmonary function testing equipment and also, to provide the highest degree of comfort to the patient.

The Polytech Filter uses media comprised of electrostatically charged hydrophobic fibers for maximal particle capture.
In addition, the flat design uses both mechanical and electrostatic means to prevent microorganisms from passing through to the patient.


Benefits of the Polytech Filter:

  • Filtration of bacteria and viruses
  • Low resistance for accurate spirometry testing,
    exceeds ATS Guidelines
  • Low dead space as required for lung volume
    and DLOC testing
  • Filter kit with disposable Nose Clip and rubber Mouthpiece
    avaliable for complete pulmonary function testing
  • Several mouthpiece styles to choose from
