Quality check recommendations

  • Visually inspect the mask for holes and separated layers by folding the mask in several places and looking for splits.
  • Place the mask on your face and block the filter support with one hand whilst maintaining a good seal to the face with the other. You should not be able to breath or blow through the mask.
  • Check the elastic supports by pulling them with thumb and forefinger to ensure the layers are firmly stuck.
  • Place filter material in place and fit the cover to check for tightness. If loose Teflon tape or similar can be wrapped round the outside of the mask nose to make a tighter fit.
