PRECIMASK® protects the wearer : it is equipped with 2 filter capsules 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 inspiration. To improve breathability, exhalation is facilitated by two exhalation valves located in front of the chin and directed downward. These valves are not equipped with filters in the current version of the mask. However, our teams are working on a version without valves or with filtered valves.

PRECIMASK® is currently undergoing filtration tests to demonstrate its equivalence to the standards in force on surgical masks (EN 14683) and FFP (EN 149). The filtration level is already equivalent to that of a surgical mask (filtration of more than 99% of particles larger than 3µm). Development is underway to obtain the filtration level of an FFP1, FFP2 and FFP3 mask.

The cleaning protocol is being validated. Cleaning of the capsules will be done simply with boiling demineralized water. The mask (transparent and silicone part) can be disinfected with conventional means. Everything will be indicated in the cleaning instructions.

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. They will be for sale on this website.

PRECIMASK® has received an anti-fog treatment inside the mask to prevent it from forming when you speak. If you wear glasses, no mist will form on your glasses because the mask is airtight. You don’t have to put any product on the mask to protect it from fogging.

No, the visor is provided with the purchase of your PRECIMASK®. You have the choice to clip it or not on the mask according to your use. It has received an anti-scratch treatment, just like the transparent face of the mask, to protect it.

How the mask works

The CE certification process is long and is done on the finished product. So, until the first masks are produced, we cannot initiate this process. However, we have carried out tests by approved laboratories, to comply with the requirements of the standards and thus be able to claim them. The technical notice will indicate all these data.

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. Our mask cannot pass the classic DGA tests because it is not made a cloth mask. In addition, since the end of June, the DGA no longer performs this type of test. That’s why we are looking to other organizations.

Certification and homologation

We are finalizing the development of the mask and the unit price has not been stopped. If you are registered on our site, you will receive information by email when the price will be available.

The commercial offer is being written. It will be available at the end of September and the site will be updated accordingly. Very large volumes will be processed directly, please contact us directly at this time.

PRECIMASK® will be available for individuals. Points of sale are currently under study.

Marketing channels are being explored and we will be working with distributors of PPE and medical equipment. The list will be defined when PRECIMASK® goes on sale.

Price and order

PRECIMASK ® is currently available in one adult size. We will initiate the development of child size in early 2021.

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 sealing of the mask. Tightening more firmly with the adjustable strap minimizes this loss.

The silicone seal that allows the mask to stick to the face, is flexible enough to fit all face shapes. In addition, the silicone fastening strap is adjustable and allows the mask to be adjusted to his face. The dimensions of the mask will be available on the website soon.

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 it was designed. It’s a bit like buying a ski goggles or a motorcycle helmet: if you take care of them, they are durable products.
