Our mobile app

The R-PUR mobile app is available exclusively with your R-PUR Nano® mask.

It allows you to track the wear of your filter to know exactly when to replace it.

The R-PUR application also provides additional information on the weather and the level of pollution around you in real time.

Real-time air pollution

R-PUR app is the first mobile application to use all the big data of air pollution collected from many national and international organizations to provide you the most accurate information.

For air pollution, we are talking about the AQI index, which includes NO2, PM10 and PM2.5 concentrations. R-PUR mask not only filters them completely but also goes even further by filtering particles that are 50 times smaller than PM2.5: PM0.05

Calculate

Monitor your
interchangeable filter

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

It calculates a precise date for filter replacement to ensure optimal protection.

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

Certificate

Authenticity
verification process

Each filter has a unique individual certificate to ensure its authenticity.

When installing your new filter, a verification process will be enabled by scanning a unique QR Code on your mobile app.

This way, you can be sure that your filter is authentic and certified by R-PUR that it incorporates all our technology.

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.
