You can buy flasks that filter water, maintained to be 100% efficient in

taken from a foul ditch, filtered and then drank. *Not by me I hasten to

Wasn't it Ray Mears who drank his own pee after using a cleaning
filter gizmo? I feel using chemicals, tablets and whatnots is so
contradictory after recycling water. Same with the Brita filter jugs -
we have one in the office and I can't remember the last time we've
changed the filter. I've never drank from it - even using electric
kettle took me years and even now it taste like plastic. I would boil
water from a saucepan. Now I use a kettle straight onto the gaz ring.
