The four-layer replaceable filter is equipped with nanofiber filtration technology. It filters pollutants, pollen, and allergens as small as 0.3 μm (micron). Unlike traditional filters, it maintains effectiveness in humid and wet conditions such as rain, sweat, and condensation from breathing.

  • Replacement nano filters are available in packs of five.
  • Nano filters come in four sizes: Large-XL, Medium, Small, and Child.
  • Choose the nano filter size that corresponds with the size of your mask skin. For example, medium nano filters insert into a medium NanoFit Mask.
  • Child nano filters insert into NanoFit Masks sizes Child and Child XS.
  • Filters come in a resealable bag, storing them securely until they are ready for use.
  • Recommended use for up to 15 days per filter.
