Hermeticity

Optimal protection would have no impact if the air enters the inside of your mask.

Our solution has passed hermeticity tests on a wide range of faces. These tests were carried out by an independent European certification laboratory.

You can access all the tests we've done.

This is made possible by the technical-shaped memory foam on our filters. It will perfectly match the shape of your face, and the tether system will adjust the facial seal of your R-PUR filter.

Breathability

The R-PUR mask will be perfectly personalized for your daily use. When travelling by foot, two motorized wheels or electric mobility, you will be able to breathe normally after three uses maximum.

Your mask will also allow you to breathe perfectly when jogging or cycling. This is made possible by our hot air extraction valve, which allows air to evacuate 60 times faster than with a conventional valve.

We have developed the most effective and protective solution on the market with our 5-layered filter.
