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.

ëTECH masks are comfortable, have an excellent seal and are
splash resistant. Also, during the treatment, they stay in place, so I don’t touch them all the time.
-Dr. Jonathan Berdugo, dental surgeon


I’m in the taxi back to New York, with your mask on. I appreciate them very much in situations where I want maximum protection. I am delighted. Thank you very much for all your efforts for the planet.
-Sylvie Erb, Ostheopath
