Reusability of Filtering Facepiece Respirators - FY10

NOTE: This page is archived for historical purposes and is no longer being maintained or updated.

Current Information can be found at: Reusability of Filtering Facepiece Respirators - FY11


  • Examine the efficacy and effect of simple decontamination procedures for filtering facepiece respirators (FFR)
  • Examine the risks associated with handling an FFR exposed to viral aerosols

Applicable Standards

  • ASTM F23.4 / E35.15
  • NIOSH 42 CFR Part 84
  • ISO TC94/SC15

Key Partners

  • FDA
  • EPA
  • ASTM
  • TSWG (funding)
  • AFRL
  • OSHA



  • Healthcare workers
  • Hospital administrators
  • Policy makers
  • General public
  • Manufacturers

Project Scope

  • Select Appropriate Decontamination Methods for Testing
  • Effect of Decontamination on FFR Filtration Performance
  • Test Protocol for Measuring the Efficacy of Decontamination
  • Measurement of the Viability of Viruses Trapped on FFR
  • Measurement of the Reaerosolization of Trapped Viruses
  • Decontamination method optimization
  • Determine effect of decontamination on FFR fit


  • Q1 Submit UV decon manuscript to a peer reviewed journal, complete multiple donning data collection, and initiate validation of BARTS II
  • Q2 Submit manuscripts for multiple decon to peer reviewed journals and complete data collection to study how multiple decon affects fit
  • Q3 Submit manuscript on Battelle reaerosolization study to peer reviewed journal and complete BARTS-II validation
  • Q4 Submit manuscripts for multiple donning, multiple decon (fit), and microwave steam bag FFR decontamination to peer reviewed journals


  • Manuscripts published in peer review journals (6 completed to date)
  • Four other manuscripts submitted to peer review journals
  • Presentations at conferences (3), Standards committee meetings & public meetings (6)
  • Contractor reports (Battelle report completed July 2008)


  • This project will provide the scientific basis for recommendations and guidance documents related to FFR reuse and handling
  • ASTM standardized test practices for measurement of decontamination efficacy of air permeable materials (filter media and respirators) contaminated with microbial contaminated droplets and droplet nuclei
