Made in Canada using top-quality Filti filter material imported from the USA.
This filter insert fits any Canada Strong or competitor face mask with pocket. Its 3.25 x 4.75" size is identical to a standard PM 2.5. For child's size, trim the material easily with scissors.
Designed for your face mask, Filti's non-woven polypropylene meltblown filter material uses patented nanofiber technology for excellent filtration and easier breathability than HEPA or activated carbon PM2.5 filters.
Filti's 3-layer nonwoven polypropylene construction exceeds standard cloth and fabric materials in filtration efficiency. Filti material filters 87-95% of 0.3 micron particles per TSI 8130 test standard. Whereas competitor PM2.5's are only designed for large 2.5 micron dust particles.
