The etrëma mask protects us and the Planet:  

In addition to its eco-responsible design, a donation of $1 per mask will be given to Earth Day Canada to support its environmental mission.

We love etrëma masks. They are light, breathable and cover the face well.

I have been wearing only PRO masks for almost 2 years. Since I work so much with patients than with specialized equipment, I have to have 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.
-Alexandre Wickham, podologue, osthéopathe


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 finally found a quality, comfortable, safe mask that limits the impact of daily use on the environment! Thank you Frett!
