Why is this better than a dust mask?

Many reasons to choose FDNS Nose Filters than a traditional dust musk:

  • More effective filtration  than most masks(up to 99.9% of Airborne Matter)
  • Much longer usage time before replacing (up to 24 hours per pair VS only 3-4 for traditional masks)
  • Much more discreet (barely visible from a short distance)
  • More easy to carry and store, especially during travel
  • Much more affordable for continuous  / long-term use
  • USA Made , Tested and Patented
