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