Silver ions target 1 bacteria-specific and 2 general metabolic mechanisms of living cells. Since viruses do not replicate outside of a host cell, the efficacy of even the last mechanism, the interference with DNA replication, is likely
very limited. With other words, I would not rely on it.

Short answer--haven't used these.
So I read through a brochure (the one from the ABSA query) and your link. No EPA registration #, no mention of the product being effective against viruses, particularly not coronaviruses.
If it doesn't state on the label that it is effective against a particular biological agent or class of interest, I'm not sure what it has going for it. The EPA registration number basically allows a manufacturer to make the claim the
disinfectant is effective against whatever agents it has been tested on and has shown a certain level of efficacy. Not all disinfectants work on all biological agents--for example, greater than 60% ethanol is effective against COVID-19 but not against Hepatitis
A.
Hope this is helpful-unfortunately, probably not the answer you were hoping for...

Are you referring to "Microban" type products?
Thank you,

Hi Everyone,
Copying a question I saw in another group, does anyone have used antimicrobial-type tapes for highly touched areas?
Can you share your thoughts?
Thank you,
Alessandra
