Filti filtration material 6" by 4" for mask pockets - 20 pieces


Product Description

  • Filti material is laser cut to 6” by 4” - it can easily be trimmed with scissors to fit the pocket size on any cloth face mask.
  • Filti material contains no fiberglass. It is a spun non-woven material with a polyester surface layer.
  • Filti material is tested to be MERV 16 compliant - this means it will filter 95% of particles as small as 0.3 microns (human hair for reference is about 50 microns) and yet is still very breathable material.
  • Comparative efficiencies are: Polyester / cotton tights 2.5%, Polyester dress shirt 2.5%, Cotton shirt 9.3%, Microfiber dish towel 14.5%.
  • Filti material is also available as fully laser contoured pieces for use in the innovative Signature Composite Mask. This mask design eliminates the need for pockets to allow the use of Filti material.
  • Price includes first class mail shipping - please note that tracking numbers can not be supplied with first class mail.
