Frequently Asked Questions

Quel masque est fait pour moi ?

Depuis 2016 et le développement de notre premier modèle, trois modèles ont vu le jour chez R-PUR.

Chaque modèle nous rapproche un peu plus de notre mission principale qui est de protéger toutes les personnes de la pollution de l'air.

Il peut être parfois difficile de choisir quel masque sera le plus adapté pour vous protéger au quotidien. Aucune inquiétude, nous sommes là pour vous accompagner dans votre choix.

En mobilité ou en effort : la gamme Nano est celle qu'il vous faut

La gamme R-PUR Nano a été spécialement développé pour les personnes en mobilité ou en effort sportif.

Nano Light : adapté avec un casque, renforcé pour les fortes vitesses - Il sera parfait pour un usage en moto et en hiver.

Nano S : système d'achat dédié au mouvement, ultra respirant - Il sera parfait pour un usage en vélo, trottinette, course à pied et en effort.

À pied, en métro, en avion ou en intérieur : la gamme FiiT est pour vous.

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.

Does our mask protect against viruses?

We filter particles up to 20 nanometers in size, so we will filter out most existing viruses.

In the current case of Covid-19, the R-PUR mask will be able to protect you effectively and also protect your close ones thanks to our stop-valve system.

In addition to the protection capacity, we must also take into account the hermeticity factor.

Indeed, depending on different face shapes, your mask will be able to filter 99.98% of the ambient air, which will make it your most effective ally against the spread: we know for example that sputters are carriers of the virus.
