Made in North America using top-quality Filti filter material from the USA.
Filti is highly-efficient: up to 95% on sub-micron particles.
3.25 x 4.75" size fits any Protect Styles or DIY face mask with pocket. Same size as standard PM 2.5. For child's size, trim the material with scissors.
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.

Non-Woven Polypropylene 3-layer Filter 10-Pack ($1.40ea)
Very nice. Thank you.
These filters are very tiny and far too small to be effective. I would not order these again.
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.
