"Polypropylene fabric masks as good as N95
Marketplace's test found some masks are just as good as an N95 when it comes to filtering out those potentially harmful particles, including one made with something called polypropylene fabric.
...Blue three-ply surgical-type disposable masks also reported some of the highest filtration efficiency rates in the Marketplace test, which was of no surprise to Scott, as most contain that melt-blown, non-woven polypropylene fabric.
"It's this interwoven matrix of fibre. Air needs to travel around each one of those fibres and it meets the next fibre and it needs to bend its path. So as it does that, those fabrics pull out lots and lots of particles," said Scott.
