When quality matters most

This is a legitimate question, especially when recalling the conclusions of the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) in 2018, which stated that the anti-pollution masks sold at the time were largely ineffective against fine particles due to a lack of airtightness and filtration.

But since then, things have changed. In just a few years, anti-pollution mask technology has evolved considerably.

At R-PUR, our anti-pollution masks use filtration technology superior to the FFP3 standard, as we filter very fine particles down to 50 nanometers (PM 0.05).

In terms of airtightness, depending on your face shape, our anti-pollution mask is capable of filtering 99.86% to 99.98% of outside air, thus attesting to the effectiveness of our anti-pollution mask.

FFP3 is the highest European standard for respiratory masks. It filters at least 99% of airborne particles — including ultrafine pollution, toxic dust, and harmful pathogens.

This makes it comparable to the N100 standard in the US, offering exceptional protection against air pollution and fine particles.

R-PUR masks are built to this level of performance and go even further, thanks to our patented nanofiltration technology.

Yes — and even beyond. While N100 masks filter out at least 99% of particles down to 0.3 microns (PM0.3), R-PUR’s mask with filter uses patented nanofiltration technology to capture particles as small as 50 nanometers (PM 0.05).

It protects you from gas, diesel fumes, fine particles, pollen, and other invisible pollutants in the air.

Maximum protection — without compromise.

Absolutely. Our mask with filter was specifically designed to protect against ultrafine particles, including PM2.5, diesel particles, and toxic pollution found in urban environments.

Thanks to its 8-layer nanofiltration system, it captures particles as small as 50 nanometers — far smaller than PM2.5 or even PM0.1.

It’s one of the most advanced filtration masks available today — and it’s built for real-world pollution.

Yes — our mask with filter is highly effective against pollen, dust, and other airborne allergens.

Its nanofiltration system blocks even the smallest particles that trigger allergic reactions, including seasonal pollen and fine pollution.

It’s an ideal choice for people suffering from hay fever or environmental allergies, especially in spring and summer.

Yes, the R-PUR mask was designed for daily use in real urban conditions.

Its adjustable shape, flexible materials, and internal airflow system allow for smooth breathing, even in hot weather.

It also helps to regulate humidity and temperature inside the mask — unlike many basic masks.

The R-PUR filter typically lasts 6 to 12 weeks, depending on your environment and how often you use it.

You should replace it if you notice increased breathing resistance or visible signs of wear.

In highly polluted areas or with intensive use, earlier replacement may be necessary.
