The Magabi protective mask is very soft and silky, made with a hypoallergenic fabric produced in Poland with an extremely dense weave. It is shaped and adheres well both on the face and on the nose, as well as laterally and under the chin. It closes with two elastic bands that can be tied independently to decide the length. It has 99.9% filtering capabilities on both inlet and outlet for anything larger than 0.1 microns. It is washable up to 90 degrees in the washing machine (it should not be ironed and it is recommended not to exceed 60 degrees in order not to damage the elastic bands: tie them before washing). It is available in 3 sizes: XS for children, S for children and small adults and L for adults. Internally on the nose there is a slot in which to insert a rigid core (not included) to shape it even better and make it more adherent. If used continuously it would be good practice to change it every 4 hours because the vapors of the breath, by moistening it, make it a breeding ground for the germs and bacteria expelled from the body. The 2-layer version is externally covered in colored cotton jersey (the elastic bands supplied can be surgical or soft ones).
