To ensure adequate functioning of your Stef Mouchie mask, make sure the filter is inserted correctly along the inside of the mask. *Filter sold separately.

After washing your hands, hold the mask and place loops around each ear stretching the mask to fit comfortably over your nose and mouth. Hold both of the ear loops and lift gently to remove the mask.

It is advised to wash the mask after every use. Remove filter before washing. We recommend using regular detergent in a delicate cycle.
