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 – FY10


  • 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
Temperature monitor on (S C B A)

Applicable Standards

  • ASTM F23.3 / E35.15
  • 42 CFR
  • ISO TC94/SC15

Key Partners

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



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

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
  • Effect of Decontamination on Respirator Fit
  • Produce Guidance Documents


  • Q1 Submit Task 2 manuscript for development and validation of a droplet test method (DPARTS) to a peer reviewed journal.
  • Q2 Submit Task 6 fit-test protocol to HSRB.
  • Q3 Submit manuscript on effect of decontamination methods on FFR strap elasticity to peer reviewed journal.
  • Q4 Submit Task 6 manuscript on effects of decontamination on FFR fit for internal review.


  • Manuscripts published in peer review journals (4 completed to date)
  • Presentations at conferences (approx. 3)
  • Standards committee meetings & public meetings (approx. 5)
  • Contractor reports (Battelle reports completed July 2008)


  • This project will provide the scientific basis for NIOSH recommendations related to the reusability of filtering facepiece respirators
  • ASTM standardized test practices for measurement of decontamination efficacy of filter media and respirators
