Project Scope
- Measure filtration performance of filtering facepiece respirators against nanoparticles
- Using manikin head form measure face seal leakage and filter performance of respirators against nanoparticles
- Determine most penetrating particle size for surgical masks, dust masks, N95, P100, and FFP2 filters
Milestones
- Q1 Submit two manuscripts to journals
- Q2 Submit a review article on nanoparticle filtration of respirators for publication in the special issue of Journal of Nanoparticle Research
- Q3 Submit manuscript on “Protection factor measurements using PortaCount” to journal
- Q4 Submit manuscript on “Leakage of nanoparticles through filtering facepiece respirators” to journal

Outputs
- Manuscripts published or submitted to peer review journals (approx. 4)
- Presentations at conferences (approx. 19)
- Standards committee meetings & public meetings (approx. 3)
- NIOSH Best Practice Nanotech Guidance Documents
Outcomes
- Experimental data from project is used in NIOSH, ASTM, & ISO guidelines for worker protection against aerosolized nanoparticles
- DuPont uses NIOSH recommended test procedures for collecting data on barrier materials and filter media
