[0035] Such as figure 1 and figure 2 Schematically shown in , the mask 1 of the invention has an overall shell shape and it is intended to be positioned on the face of a user 20 to cover the user's nose, mouth and chin along with parts of the cheeks while being held by the back of the head via the strap 8.

[0036] The mask is made of filter device carrier 2 and detachable filter device 11, such as Figure 4 and Figure 5 can be seen in.

[0037] The filter device carrier 2 comprises a central part 3 surrounded by a peripheral part 4 . In the described embodiment of the invention, the central portion conceals and protects the filter device 11 while allowing air to pass easily to and from the mouth and nose of the user 20 . To this end, the central part may be in the form of a porous material, a material made of woven or non-woven fibers. It can also be used as a pre-filter, eg for filtering dust present in the air.

[0038] In this embodiment, the peripheral part 4 of t...

The filter (11) is positioned to be abutted against the inner concave face of the filter holder (2), preferably matching the shape of the concave face of the filter holder. The mask is characterized in that the straps (8) for holding the filter holder (2) cooperate with the filter, so that the filter is positioned to be abutted against the concave face of the filter holder.

Description

technical field [0001] The present invention relates to the field of protective masks (masks), and more particularly to anti-pollution masks (masks). Background technique [0002] Anti-pollution masks such as those used by cyclists, motorcyclists or walkers and currently on sale can be divided into two main categories. [0003] The first category has a general shell shape and consists of a body made entirely of filter material together with a retention strap that goes around the ear or around the back of the user's head. Due to its simple design, the filter is lightweight, but it cannot be pressed against the user's face. Furthermore, it requires periodic replacement: either the filter device together with its retaining band if it is fixed to it, or only the body of the filter device if the retaining band is detachable. In this case, there is a risk that the hold strap will not be found or lost. [0004] In order to keep the filter in place and press more forcefully again...
