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.
