Hi Alex,

Thanks for the link. Just be really careful with the nano-silver.
Check the supplier and see if they have done independent testing.

Probably 90% of the nano-silver products lose some of their silver with every wash. This causes two problems #1 it doesn't work as well with each wash. #2 Nano-silver (while safe for humans) is absolutely deadly in lakes/river ecosystems.

Since all of my water goes back into lakes I wish to be very careful in the products I use/buy.
