The Katydyn water filters are indeed fabulous. Absolutely – and quite literally – life support.
And it is crucial for each individual – and potential group – to assess their own potential water needs and to carry sufficient filtering capacity on the road.
In that light, and because
every single survival website says the same thing: i. e. You cannot have “too much” potable water...! I have taken their warning to heart and purchased the slightly-larger but still very lightweight Gravidyn model from Katadyn that uses state-of-the-art ceramic filters (note to self : buy backup filters!) -
http://www.katadyn.com/usen/katadyn-products/products/katadynshopconnect/katadyn-water-filters-endurance-series-products/katadyn-drip-gravidyn/ This one is a bit larger than the personal size knapsack model you’ve already got – whose survival value cannot be disputed – but still lightweight and if I ever
really, really needed potable water for myself and others .... fabulous. I know I will not be alone in my need for potable water.
Also important/ must see: the seriously major
Katdyn "Expedition”
http://www.katadyn.com/usen/katadyn-products/products/katadynshopconnect/katadyn-water-filters-endurance-series-products/katadyn-expedition/ model. A hand-operated large-capacity model worth considering as something that
your local government should be stashing in quantity against real shutdown, flood or other water scarcity. It would not be stupid to urge your local government to buy a dozen, twenty or so of these – at minimum - to be kept under lock-and-key in dispersed locations (in police stations?) against almost-certain need at some point. So cheap now; so priceless later....
Worth considering also:
the Big Berkey water filters:

What – I ask you – is the downside here? Think!
