Interesting idea for water sanitation

Scientists at McGill University have developed a water filter paper impregnated with silver particles.  The silver acts as a bactericidal agent while the filter obviously takes care of the larger floaties.  It's primary intent is to be used in disaster areas where clean drinking water isn't readily available.  However, if it proves efficacious, then perhaps it migrates into the outdoor recreation industry. While the article doesn't mention viruses or spores, it will be interesting to see if this evolves from idea to product.

Love this idea.  Have you heard of using 1L bottles to purify water, too?

This is actually not a new idea. A number of public water treatment plants here in the US have been using silver for decades to treat water. Expense has kept it from going mainstream though.

I have a colloidal silver generator in my backpack. I only use it for extended stay. Silver is at a high right now. These filters will only add to the demand for silver.

Yeah, I would imagine that filters like that would be cost-prohibitive, unless the could be reused (I think they would be reusable, as the silver would stay impregnated in the filter).
