Here's another document from Honeywell stating the main material is "flexible non-woven polypropylene fabric" https://www.honeywell.com/en-us/newsroom/news/2020/03/n95-ma...

Here's the link to Wikipedia and I quote "The N95 mask requires a fine mesh of synthetic polymer fibers, also known as nonwoven polypropylene fabric,[5] which is produced through a highly specialized process called melt blowing that forms the inner filtration layer that filters out hazardous particles.[6]" https://en.wikipedia.org/wiki/N95_mask
