The strips are used to create an airtight seal on any face mask to help keep masks in position, optimize filtration, and reduce eyeglass fogging. 

Practicon now carries ADDaSEAL Adhesive Face Mask Strips. 

An airtight seal is created by peeling and sticking ADDaSEAL onto the nose bridge of any face mask. The 3M medical-grad, hypoallergenic adhesive adheres to the skin to keep face masks in position, optimize filtration, and reduce eyeglass fogging. 

The strip can be disposed of along with the mask or reapplied on reusable face masks.
