    My only concern with this and don't get me wrong it is a brilliant and very scalable idea. But once the filters expire as all filters do generally after a few months what's to stop those with them not drinking from contaminated water and thinking that they are safe? I am sure there is a simple explanation but ideas like this seem great from the outset but the continued life sometimes is overlooked.
