“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.
