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


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.


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.

Water repellant layer

The first water-repellent layer of your filter will filter out coarse dusts as well as liquids.


Nano Filtration®️ technology

The two nanofiltration layers with electrostatic filtration filter out particles up to a size of 50 nanometers.


Activated carbon layer

This activated carbon layer blocks harmful gases and odors so that you can breathe perfectly pure air.


Easy-to-breathe memory fiber inner layer

Thanks to this technical anti-humidity layer, you can stay dry in your mask.


Soft and airtight face seal

The R-PUR Nano® mask is the most effective solution in the world at the moment.

With its 5 filter layers, it filters out gases, odors, pollen, bacteria, viruses, fine/very fine particles, diesel particles and toxic particulate matter (PM) linked to air pollution.

R-PUR Nano® is the first truly effective nanofiltration solution against harmful particles that are extremely fine.

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.
