Seriously though, I'd rather not be in a place where the water is contaminated with heavy metals, chemicals, and pesticides where I must collect it and use a water filter. It'd be fine for a survival/bugout situation like living through a natural disaster. I mean I've hiked 20-30 miles into places to camp and always brought enough water for a week (3gal@25lbs). Though, no longer since it is normally boring as fuck after a week anyway. It seems like the advertising reasons on their website are sound.
