FAQ for the C50

Avon can provide you with a sizing tool which helps to assign the right size of mask. Also, as a rule of thumb, your eyes should be at, or just above, the centre line of the eye lens.

Wearers must always conduct a negative pressure fit check prior to use to make sure the mask will seal to the face. Also wearers are advised to conduct a quantitative fit test, at least annually, to confirm the correct face mask size has been selected. Only use a mask if a fit check is satisfactorily completed.
