FITTING INSTRUCTIONS:

2.     Place the mask against your face holding it with one hand with its lower part on your chin, the nose clip on your nose and the elastic straps between your hand and the mask. Pass the lower strap over your head and place it down your ears, on your nape.
3.     Hold the mask with one hand on your face with a soft and firm pressure and with the other hand, fit the upper strap over your ears.
4.     Using both hands at once adjust the whole extension of the nose clip to your nose's shape, place the elastic straps in a good position to get a proper face adjustment and , finally, make sure that all the edges of the mask are in direct contact with your face.
5.     Fit test. It helps to verify if the mask is properly fitted. For that, cup both hands over the mask and exhale vigorously. If air leaks through the edges, you should modify the position of the mask on your face, adjust again the nose clip and/or modify the tension or position of the elastic straps. Repeat this process until no leakage is detected.
