Made in Canada using top-quality Filti filter material imported from the USA. Graphene-free.
This filter insert fits any washable reusable cloth 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.
Filti's next-generation 3-layer construction uses nonwoven spunbond polypropylene and patented lightweight nanofiber technology in the middle layer for filtration and easy breathing.
How to use:
- place insert into cloth mask pocket so that deeper bond points and fluffy/lofty texture face outwards, and the side with less loft and shallower bond points faces inwards
- between wearings, leave filter in-mask exposed to room air so it can dry
- after 8 hours of accumulated wearing, dispose of filter and wash mask
- NOTE: these are for washable cloth masks and are not intended for use with respirator masks.
