It is the first window mask (June 8, 2020 then July 17, 2020) to have received the results of tests carried out by the DGA (Directorate General of Armament of France) in accordance with the interministerial information note of March 29, 2020, revised on April 26, 2020 for non-sanitary use of category 1, filtration at 98% tested on a new face mask and after 20 washes!

This is a mask intended for professionals who have to meet a large number of people during their activities (law enforcement officers, cashier, etc.).

Air permeability must be greater than 96 L.m².S-1 according to the DGA.
Air permeability of our new protective mask: 449 L.m².S-1.
Air permeability of our protective mask after 20 washes: 573 L.m².S-1.

Protection efficiency against aerosols (3 micron particles) when new: 98%. Protection efficiency against aerosols (3 micron particles) after 20 washes: 98% (!!)

REMINDER :
- This device is neither a medical device within the meaning of regulation EU / 2017/745 (surgical masks), nor personal protective equipment within the meaning of regulation EU / 2016/425 (filtering masks of the FFP2 type). It is not intended for use by healthcare personnel in contact with patients.

The interministerial information note of March 29, 2020, revised on April 26, 2020 relating to the new categories of masks reserved for non-sanitary uses imposes a filtration efficiency of particles with a diameter of 3 μm emitted from:

- Category 1 (individual mask for use by professionals in contact with the public): Efficiency> 90%

- Category 2 (protective mask for collective purposes to protect an entire group wearing these masks): Efficiency> 70%.

A new window mask protocol is in progress. Our tests were carried out on the basis of the new protocol.
