Madison Element & 3d Disposable Face Mask Inserts Pack Of 10

Designed to be used with our Element & 3D reusable face coverings.
This 5-layer filter adds additional protection to our face covering
Non-woven inner and outer layers prevent larger dust particles from passing through and provide structure and support for the finer filtration layers
Polypropylene melt-blown layers prevent smaller particles from passing through the filter down to a size of approximately 3 microns
The activated carbon is a highly microporous filtration layer which absorbs smaller gaseous impurities via chemical adsorption
Filter should be replaced after 12 hours of use
