This is a Filter that can be inserted into the pocketed style facemasks we sell. The card enclosed will show you which side should be next to your face.
 
Is the face mask material washable?
It has been recognized by “Advanced Filtration Manufacturers Association (AFMA)” that advanced materials used in face mask filtration should not be washed due to the material damage and decrease in filtration quality.
 
If you have a UV light you can use it on the filter to kill off the germs to re-use it without harming the physical structure of the filter.
 
Tip: Your facemask should be washed as a UV light only kills germs but does not remove odors or makeup.
