Made in Canada by Canada Strong Masks using top-quality Filti NP097 filter material imported from the USA.
This filter insert fits any face mask with filter pocket. Its 3.25 x 4.75" size is identical to a standard PM 2.5. For child's size, the material trims easily with scissors.
Designed for your face mask, Filti's 3-layer polypropylene spunbond non-woven and nanofiber construction uses patented lightweight nanofiber technology for excellent filtration and easier breathability than activated carbon PM2.5 filters and HEPA filters.
Filti 's performance exceeds standard cloth and fabric materials in filtration efficiency. Filti NP097 filters 87-95% of small 0.3 micron particles per TSI 8130 test standard. In contrast, competitor PM2.5's are designed for large 2.5 micron particles found in city air pollution.
Reduce droplet transmission with better filtration technology by Filti.
- place insert into mask pocket so that deeper bond points and fluffy/lofty texture face outwards, and the side that feels silky-smooth faces inwards
- between wearings, leave filter in-mask exposed to room air so it can dry
- after 8-12 hours of accumulated wearing, dispose of filter and wash mask
