Nanotechnology Antibacterial 5 Layer Filter for Facial Masks

Patented nanotechnology.
Five layers filtering for high breathing protection.
The nano silver antibacterial filters are effectively improve the antibacterial efficiency of masks.
The nano silver particles in the filter offer strong antibacterial protection and bacteriostatic function, as they are not dissolve in water or body humidity but actually increase their effectiveness by producing silver ions through slow release for a long time.

The nanotechnology filter offers five layers of advanced filtering:
The first layer (surface layer) is 25-30g/m2 PP non-woven fabric,
The second layer is 25g/m2 melted spray fabric for filtration,
The third layer is 38g/m2 nano silver antibacterial non-woven fabric,
The fourth layer is 20g/m2 melted spray non-woven filtering fabric
The fifth layer (inner layer) is 20g/m2 water-wet PP non-woven fabric.

Dimensions: 8 x 12 cm.
