*The differential pressure (ΔP) is used to assess breathability: it is the difference in pressure measured between the inside and the outside of the mask when a fixed volume of air passes vertically through a fixed surface of its multilayer textile per unit time (this volume is called air permeability, from which breathability is derived).
The lower the differential pressure, the greater the air permeability of the textile multilayer, therefore the greater (better) the breathability of the mask.

Patented ëncore® Filtration Technology

  • Structural OPTIMIZATION of fibers for medical performance in filtration and breathability without unstable or toxic treatments (electrostatic, additives, nanomaterials, etc.).
  • Mutual PROTECTION of the layers for day after day durability and control of the loss of fine fibers by friction, wash after wash and during handling.
  • RETENTION of fibers in superimposed textiles for maximum safety, without dispersion outside the multilayer and without contamination of users and the environment
  • RESISTANCE TO LIQUIDS such as the projection of synthetic blood at 160 mm of mercury pressure (mmHg).
  • ZERO WASTE and CIRCULAR,  all features are recyclable or recovered to become polypropylene pellets or fibers

Medical certifications meeting the requirements of the

CNESST and Health Canada.

  • Tested in ISO 17025 laboratories
  • Complies with North American ASTM F3502-21 standards and requirements

“As soon as I put on the Frëtt mask, I felt protected on all sides. The usual blue disposable masks let the air pass through the sides and are not adjusted. With the Frëtt mask, it’s just the opposite. Very comfortable mask. I liked having the option of leaving it around my neck with the removable cord.”

Isabelle Noël – Montreal



So much better for the environment than disposable and without compromising the protection. I have been using them for over a year with great satisfaction.

I have been wearing only PRO masks for almost 2 years. Since I work with patients as well as with specialized equipment, I need a versatile mask. In addition to being able to wear it for a long time, it doesn’t prevent me from talking to people or on the phone without having to remove it.
