Frequently Asked Questions
How are our masks used?
For the Sirocco: The Sirocco uses a moulding to adapt to the morphology. Heat the inner lip with a hair dryer, between 3 to 5 cm of the foam and for 10 seconds. Insist at the level of the nose. Put on your glasses then the mask. Press around the nose for 10 seconds. Repeat the operation until the desired comfort is achieved. Put the filter inside once the mask is ready. Several possible attachments: behind the ears and the nape of the neck. The French Mask has a metal bar to take the shape of the nose. Place the mask with the fasteners behind the ears and place it so as to protect your nose and up to 1cm below the chin. Adjust its position with the nose clip.
What is the care of the Mask?
Our masks are machine washable up to 60 degrees. Only the Sirocco can be washed by hand. We can also advise a leather care and maintenance with creams available on the market.
Is the filter washable?
No, our filters are not washable. Our filters are disposable after a few days depending on your use.
How long does it take to change the filter?
A filter, depending on your use, can last up to two weeks. In periods of pollution peaks or viruses etc, we recommend changing it every week (3 days for people in daily contact with sick people, people at risk or in contact with a lot of dust etc). Our estimate is an average. This duration varies from one person to another depending on the type of use (work, travel, outdoor activities, etc.), the environment (urban, rural), the daily duration of use, etc. Regular washing of the Mask is recommended to limit the spread of germs.
Since our tests were conducted under conditions of extreme exposure to ultra-fine particles (conditions not encountered in everyday life), the results of these tests indicated a validated filtration capacity for 8 hours. We confirm that our filters can be used for a period of 10 days in the context of corporate use, or in the context of daily life activities.
A feeling of fraying is a marker for changing the filter.
Is the Mask adapted to protect itself efficiently from Covid-19?
Our masks are adapted to protect against Covid-19. The virus is filtered with ultrafine particles (up to 0.3 micron). Indeed, the diameter of the microdroplets emitted by the respiratory tract varies from 5 to 150 microns.
Optimum filtration against fine and ultrafine particles, well beyond the standards required for coronavirus. Tests carried out in a laboratory specialized in the medical field: Nelson Labs.
1-Filtration always effective from 3 microns to 0.3 microns.
2-Filtration higher than 99%.
3-Materials also designed for protection against viruses.
Is the mask suitable for wearing glasses?
Our masks are adapted to the wearing of glasses. They are also anti-fogging for enhanced comfort. Our advice: make a moulding of the nose bridge around your pinkie so that it takes the shape, then put and adjust the mask and its bridge on the nose.
