Filti's nonwoven / nanofiber / 3-layer construction exceeds standard cloth and fabric materials in efficiency percentage. Filti filters up to 95% of 0.3 micron particles per TSI 8130 test standard. In contrast, competitor PM2.5's are only designed for large 2.5 micron dust particles.

Very nice. Thank you.
A very well made mask with a sewn in pocket to add in an additional disposable filter. The Protect Styles mask can also be washed as an additional way to keep the mask clean.
