How long does a filter last ?

Our Zephyr algorithm aggregates the average number of kilometres travelled with air pollution data on each route.

It calculates a precise date for the filter replacement in order to guarantee optimal protection.

On average, the filter is replaced after 5 to 15 weeks of daily use, depending on your personal usage and the level of exposure to air pollution.

Combien me protéger au quotidien va-t-il me coûter ?

Votre masque est garanti pendant cinq années, vous n'aurez donc pas de souci à vous faire s'il rencontre un souci.

Are our masks suitable for sports?

During our two years of research and development, we sought to obtain the most protective and breathable solution.

This has been possible thanks to a careful selection of breathable technical materials, the development of a dedicated valve and tests on numerous sportsmen and women.

Our special attachments allow the mask to stay in place even during movements, and the shape memory foam ensures that the mask remains perfectly airtight during your sports sessions.
