Multi-Scale Microstructure Investigation for a PM<sub>2.5</sub> Air-Filter Efficiency Study of Non-Woven Polypropylene
A N95 face-piece respirator and a 3M air filter composed of non-woven polypropylene filter material were investigated for their multi-scale microstructure and resulting filtration performance. Filtration mechanisms of each system are found and quantified. Both media showed a gradually decrease of th...
