>>915144The Sawyer is great. I used it on the PCT to hike 2,600 miles of desert, forest, alpine terrain. I like the regular size because of the faster flow rate. Used it with an Evernew bottle and a Platypus drinking bladder. Two containers is good so that you can add electrolytes to the clean bottle. If you have just one container, you’ll have to add them to the dirty water and possibly end up filtering them out plus getting sugar into your filter.
> b) a water filter connected directly so that you can stick e.g. a hose in water source and pump it through the filter straight into the reservoirIf you're looking for a pump, then a Sawyer won't work. You could get the MSR Guardian.
