HICI Pure Copper Mesh Blocker Copper Screen Mesh Distilling (5"X20 FT)

Hundreds of years ago the Romans lined their water tanks with copper. I am using this copper with my air filter and hope that it helps kill virus in my home. It is known that copper kills some virus and germs on contact. Withe Corona it takes several hours to kill the virus. Hope it works.

This stuff works great. I just tucked it into the cracks of my storage garage and voila! No pesky rodents to worry about.
