    1.The material may change color due to storage or temperature conditions. This is normal.

    2.If the mask irritates the skin or there is a bad odor, stop using immediately and consult a doctor if necessary.

    5.Change the insert weekly to ensure antimicrobial effectiveness.

    6.Avoid use where sulfur is around (such as hot spring areas) as the silver may react with the sulfur and make the mask less effective.
