Frequently Asked Questions

Are anti-pollution masks effective?

In July 2018, the ANSES wrote a negative report on the effectiveness of anti-pollution masks.
This report was based on mask tests carried out in previous years, which is the reason why we created our mask at the time: no anti-pollution mask was effective.

We hope that our mask can be included in the next ANSES report with the associated tests.

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.

What is the difference between the Nano One and the Nano Light model?

The Nano Light® mask has the same filtration technology as the Nano One®.

We have come to modify the outside part of the mask in order to adapt it to the safety constraints of a cyclist. For instance, to be more visible on the road: this is why we made it reflective.

It is also more breathable when cycling or running.

The R-PUR Nano One® mask, for example, is much more resistant to cold temperatures: this is a specific constraint for motorcyclists when they ride at high speeds in winter.

In the end, the two models are the same in terms of technology and filtration. We have chosen to widen the range to be able to offer effective solutions that meet the specific needs of each use.
