PRECIMASK® protect the wearer and his environment: it is equipped with 2 filter cartridges positioned on the cheeks, which clip onto the mask. These sealed capsules contain a ceramic material developed by St Gobain which filters the outside air on inhalation and exhalation.

The PRECIMASK® have passed filtration tests to demonstrate their equivalence to the standards in force on surgical masks (NF EN 14683 AC). The level of filtration measured is equivalent to that of a surgical mask: filtration of more than 95% of aerosols of 3 µm and more. The mask also has a enhanced air tightness with a very low leak rate and lower than FFP2 masks. This feature considerably improves its level of protection. Development is underway to obtain the filtration level of an FFP2 mask.

You will also find in our web page “ Why PRECIMASK ? ”, the details of the different standards and the reasons why our mask is particularly suitable for your protection.

The size of the pollens is generally between 7µm for the smallest and 150µm for the largest. The pollens will therefore be filtered through our filter cartridges which retain more than 95% of particles of 3µm and larger.

The daily cleaning of the filter capsules is done in the oven at 90°C (200°F) for 10 minutes. The rest of the mask should be washed off with hot soapy water, or with a virucidal cleaning solution. This cleaning is recommended after a day of wearing the mask to ensure viral activation and to properly dry the cartridges, especially if the mask is used in a humid environment.

Contraindications: do not expose masks and cartridges to high heat, to a flame, to liquids other than those recommended.

No, once you have purchased your PRECIMASK®, there is no more consumable to buy. You can purchase new capsules if you need an additional set or want to change colors !

PRECIMASK® is very airtight. As a result, the moisture given off by the skin and by breathing will remain inside the masks, which can form fogging or even condensation on contact with the masks, especially if the outside temperatures are cold. It is an inescapable natural phenomenon. This condensation on the walls of the masks results in small droplets of water, collected in the silicone chute. You just need to wipe the inside of the masks regularly. If you wear glasses, no mist will form on your glasses because the mask is waterproof at the nose.

How the mask works

CE certification applies to surgical masks and FFP or FMP. In its current configuration, PRECIMASK® do not fall into one of these two categories : it has the architecture, and therefore the tightness, of an FMP type mask and the filtration level of a surgical mask.

PRECIMASK® meets the requirements defined for “general public” or “UNS (non sanitary use)” type 1 masks. You can find the UNS certification of PRECIMASK® by clicking here

During containment, the DGA implemented an approval for tissue masks, disposable or washable, so that a large number of masks can be put on the market quickly. PRECIMASK® is not a cloth mask and therefore cannot be approved by the DGA.

Certification and approuval

Considering the following data :

  • Electricity price France 2020 = 0.15 € / kWh
  • equivalence France, 1 kWh = 0.1kg CO2 (source: greenIT.fr)
  • equivalence Europe, 1kWh = 0.45kg CO2 (source: greenIT.fr)
  • Tree CO2 absorption 5 m3 = 5000kg / year CO2 (source: office national des forêts)

We have calculated that if you clean your filter cartridges every day (in the oven at 90 ° for 10 min) the annual cost of this cleaning is 5.1 €. For monthly cleaning (30min boiling – excluding the cost of water – and drying the cartridges in the oven), the annual cost is 3.2 € more. So cleaning your filter cartridges according to the indicated protocol will costs you only 8.3 € per year.

This is also equivalent to a carbon footprint of 5.6Kg / year. This figure is compared to the 5000kg / year that a tree absorbs. In other words, a single tree can absorb the equivalent of the carbon footprint of cleaning 900 masks 😊

Price and order

Absolutely because the mask is waterproof, airtight and has no cloth part. Its use in the rain therefore allows you not to have the lower part of your face wet.

PRECIMASK® Air is available in three different sizes :

  • Size S ideal for women and children (from around 10 years old depending on the child)
  • Size M ideal for men
  • Size L ideal for those with a rounded face or with a full beard

More info here : precimask.fr/en/features-and-technical-data

The silicone seal that allows the mask to stick to the face, is flexible enough to fit all face shapes. However, a beard can decrease the seal of the mask and thus cause leaks. Tightening more firmly with the adjustable strap helps to minimize this leakage.

The silicone seal that allows the mask to stick to the face, is flexible enough to fit all face shapes. In addition, the silicone attachment strap is adjustable and allows the mask to be adjusted to his face.

PRECIMASK®  is a very technical product without perishable material or to replace. If you use and maintain it correctly, just like any other technical product, it will continue to perform the functions for which they were designed.

The shelf life can be more than 40 years for masks and filter cartridges under suitable storage conditions. Please refer to the different user manuals available here : precimask.fr/en/maintenance-and-cleaning
