Perhaps this is more for a legal group? Someone in Oldham is selling a
colloidal silver spray device in a gateway that is supposed to 'sterilise'
customers. The rationale on the website is largely nonsense, and carefully
fails to directly address the problem of customers exhaling virus, which is of
course the main problem.

Meanwhile there is evidence that a colloidal solver mist may be toxic to the
lungs.

The makers may of course get round the toxicity problem by only using
homeopathic quantities of silver. Since it is unlikely to do any good however
much you use this may be the best compromise.

It will be interesting to see where this goes, assuming anyone at all buys
their device.
