Face mask sealer

Improve comfort and protection of your mask by the use of a face mask sealer

Face mask fitter / sealer – create the perfect fit

Face masks are usually “one-size-fits-all” and do not guarantee a perfect, protective sealing. The face mask sealer is a 3D printed frame, helping to improve the sealing of masks and reduce air flow.

Product features:

  • 3D printed in TPU
  • Use on top of surgical mask or home made textile mask to reduce air gaps and improve safety
  • Mask seal follows contour of your head to ensure a good fit
  • Adjustable strap for optimal wearing comfort
  • Eliminates foggy eyeglasses or face shields
  • Different sizes available – see chart
  • Reusable and washable at up to 90°C
  • Certified and lab tested FFP2 level op protection  


DISCLAIMER! The mask sealer can be used in combination with a medical face mask. The mask sealer itself is not a medical device and therefore does not need to comply with the medical device regulation.
